The Division of Cardiology at SickKids was established in 1938, as one of the first dedicated units treating children with congenital heart disease. Over 80 years later, the Division remains one of the most prestigious and productive in the world.

As an integral partner in the Labatt Family Heart Centre, it forms an important part of a multi-disciplinary and “expert model of care” team, with dedicated cardiac intensive care facilities, world-leading imaging teams, internationally renowned interventional cardiology and electrophysiology services, and one of the largest heart function and transplant groups. 

Our vision is to be the global leader in transformational congenital cardiac care.

Programs and Services

Expand the sections below to learn about programs and services offered at SickKids Cardiology.

What is Cardiac Catheterization?

The Cardiac Diagnostic and Interventional Unit (CDIU) unit consists of highly specialized doctors, nurses and other health professionals who diagnose and treat a variety of heart conditions.  

Using a specialized catheter, which is a long thin tube, and other small flexible tools, doctors can seal holes or open holes of the heart, widen narrowed passages, repair valves and obtain a sample or biopsy of the heart. Doctors can also gather information about the structure of your child’s heart and its valves; the pressure in the chambers of the heart and its blood vessels; the amount of oxygen in the chambers of the heart and its blood vessels; the amount of blood your child’s heart pumps to the body and the rhythm of the heart. The health-care team will use this as important information to create a clinical plan for your child. 

Additionally, the unit has an interventional Magnetic Resonance Imaging (MRI) suite, which helps doctors view what they are doing in real time without using radiation. 

Learn more about heart catheterization.

CDIU Staff Cardiologists

The Cardiac Imaging team of specialists at the Hospital for Sick Children work in the CDIU to provide expert non-invasive diagnostic evaluation in the modalities of cardiac chest x-ray, magnetic resonance imaging (MRI), and computed tomography (CT). State-of-the-art imaging techniques are specifically tailored for each patient to provide detailed individualized information about cardiovascular anatomy, function, and hemodynamics. This information contributes to treatment decision making, surgical planning, and best patient outcomes.

Our service is comprised of three core foundations:

Excellence in patient-centered clinical care

Our team is highly subspecialized and experienced. We work in close seamless collaboration with our surgical and medical colleagues in the Labatt Family Heart Centre. Each cardiac MRI or CT is directly supervised in-person by a subspecialist cardiac imaging physician expert. We are committed to always providing the highest quality patient-centered care.

Global education and training

The Cardiac Imaging team at the Hospital for Sick Children has a strong legacy of global education and outreach. We offer a one- to two-year dedicated subspecialty fellowship in cardiovascular MRI. In addition, a two-year research fellowship in cardiovascular imaging is also available.

Transformative cardiac imaging research

The Cardiac Imaging physicians partner with imaging scientists in the SickKids Research Institute to constantly advance our imaging techniques and knowledge of disease to best care for patients.

Notable areas of academic focus include:

The Cardiac Imaging team’s top priority is to always provide exemplary individualized patient- and family centered care to achieve the best outcomes.

Fetal MRI

Medical imaging plays a vital role in the diagnosis and management of fetal cardiac abnormalities during pregnancy. While ultrasound is the current standard for fetal imaging, there is growing interest in the use of magnetic resonance imaging (MRI) to evaluate the fetal heart in cases where ultrasound cannot provide a complete diagnosis.

Fetal MRI is challenging due to the size of fetal heart structures, relatively high fetal heart rates, and multiple sources of motion that occur during the scan. The Fetal MRI group focuses on novel approaches that address the technical challenges of imaging the fetus and explore new ways to assess and manage diseases that affect the fetal heart and placenta.

The cardiac clinic specializes in the diagnosis and follow-up of children with congenital or acquired cardiac disease from birth to 18 years of age. We see approximately 10,000 patient visits per year, including those who require surgery, have genetic or metabolic disorders with cardiac complications or have cardiac defects that require ongoing medical management. For further information on specific cardiac defects, please visit AboutKidsHealth.

The Cardiomyopathy & Heart Function (CHF) program was founded in 2005 and since then has been an integral section to the Division of Cardiology. The CHF program provides expertise in delivering both inpatient and outpatient care for children with heart muscle diseases like cardiomyopathies and for children with poor heart function due to a “weakheart muscle”.

For further information regarding pediatric heart failure and other pediatric cardiac conditions please see the Heart Learning Hub.

The CHF program runs a regular interdisciplinary clinic each week as well as additional specialty clinics for Hypertrophic Cardiomyopathy, Friedreich’s Ataxia, and a regular cardiomyopathy screening clinic for children with affected family members. We also provide cardiac care for children with neuromuscular diseases, such as Duchenne muscular dystrophy, and for children who have undergone chemotherapy for childhood cancers. In addition, the program runs a robust home inotrope program and is responsible for the care of children requiring ventricular assist devices (Treatment of heart failure in children).

The CHF team is comprised of pediatric cardiologists and nurse practitioners, dietitians, social workers, child life, occupational and physical therapists, pharmacists, and genetic counselors.

From a research standpoint, the CHF program is in the forefront of innovation with ongoing participation in a number of research activities that include novel drug trials, multi-centre registry participation, advanced genomics and stem cell research, Cardiac Precision Medicine, digital technology, and quality improvement efforts.

The Echocardiography Laboratory in The Labatt Family Heart Centre provides diagnostic cardiac ultrasound for children with suspected or known heart disease. We evaluate patients ranging from the fetus to childhood to adolescence. Using state-of-the-art equipment, ultrasounds are performed by highly skilled paediatric sonographers and interpreted by a world-class team of diagnostic physicians.

What to expect when you visit the Echo Lab

Follow Shaun's journey through the Echo Lab to discover what you can expect if you are coming to SickKids for one of these tests: an echocardiogram (or 'echo'), a vascular ultrasound or a bicycle stress echo!

Clinical Echocardiography

The clinical echocardiography service specializes in the recognition and assessment of structural heart defects and the evaluation of cardiac function. Studies are performed according to well-defined imaging protocols with the highest quality control. We introduced the innovative concept of functional paediatric echocardiography which uses the most advanced equipment for the analysis of cardiac function and includes three-dimensional echocardiography, tissue Doppler and myocardial strain imaging. We also provide stress echocardiography, using either dobutamine or supine bicycle, which allows ultrasound imaging of children during exercise.

The Echocardiography Laboratory provides diagnostic cardiac ultrasound for children with suspected or known heart disease. The left panel shows an echocardiographic four-chamber view of a normal heart demonstrating the right atrium (RA), the right ventricle (RV), the left atrium (LA), and the left ventricle (LV). The right panel shows a four-chamber view of a heart with hypoplastic left heart syndrome, note the small left ventricle and dilated right ventricle.

Fetal Cardiology

Our Fetal Cardiac Program (explained later on this page) performs fetal echocardiography to diagnose heart problems in developing babies during pregnancy. After the echocardiogram is performed, multidisciplinary counseling is provided by members of the team who work closely with other prenatal care providers. This program also provides fetal treatment and intervention for certain abnormalities or diseases.


We have an integrated Cardiovascular Ultrasound Research Program which develops and explores the clinical utility of newer echocardiographic techniques for the diagnosis and management of paediatric cardiovascular disease. Established in 2005, we offer a unique environment for cardiovascular imaging research where researchers, engineers, and research sonographers collaborate to study vascular and cardiac function in children.

This image, using blood speckle image technology, shows blood flow swirling inside the left ventricle of a neonate.


Our laboratory is dedicated to educating and training both physicians and sonographers. Using a structured hands-on training program, we aim to teach our imaging protocols as well as our approach to image optimization. We also offer the opportunity for observers from all over the world to see our laboratory in action. We host the Echocardiography Course on Congenital Heart Disease, which features an international faculty of experts and aims to improve the knowledge of those who perform and/or interpret paediatric echocardiograms.

The Echocardiography Course on Congenital Heart Disease held at SickKids features echo-morphology correlation lectures, live scanning demonstrations and an international faculty of experts.

Being active and playing with family and friends is an important part of childhood, and it contributes to children and adolescents’ physical and mental well-being. Understanding the best types and levels of exercise and best choices for sport or recreational activity can be challenging for children living with a heart or chronic medical condition.

The Exercise Medicine Program, created within the Labatt Family Heart Centre at The Hospital for Sick Children, is the first program in Canada to promote physical activity by providing individualized exercise programs for our patients based on a comprehensive medical and functional evaluation.


The Exercise Medicine Program at SickKids is the first program in Canada integrating Rehabilitation and Preventive Medicine into the care of children and teenagers living with congenital heart disease and chronic disease. Meet the Exercise Medicine Program team and learn about Alex's and his family's experience in the prgoram. 

What are the goals of the Exercise Medicine Program?

Our goal is to help children and adolescents improve their health by reaching a level of physical activity/exercise they didn’t realize they could achieve. We want to empower them to participate in exercise and become more active and confident about their physical abilities.

During the program we help our patients to find the right motivation, confidence, physical competence, and knowledge they need to include physical activity, sport or exercise into their daily routine for life. We want to help our patients to discover strengths and abilities they may not have known they possessed and to find joy in moving their bodies. 

Who can benefit from the Exercise Medicine Program? 

We accept referrals for any child age 8 and older with a heart or chronic medical condition that might benefit from exercise and lifestyle counseling. We provide family-based lifestyle counseling, and we deliver individualized lifestyle programs that include recommendations for physical activity, sedentary behavior, nutritional habits and sleep hygiene.

What to expect in the Exercise Medicine Program? 

Each patient undergoes a comprehensive medical evaluation including:

  • Biometric Assessment - We record height, weight, body mass index (BMI) and body composition analysis result at the beginning and end of the program.
  • Cardiac Fitness Evaluation - We use either a bike test or walk test to evaluate patients' cardiac fitness. The results of the test are used to personalize our exercise plans.
  • Quality of Movement and Muscle Strength Evaluation 
    • Our movement and strength assessment involves the performance of 5 basic exercises
    • By observing patients performing these simple movements the program's kinesiologist is able to evaluate the quality of their movement and their level of strength
    • The results of this evaluation are used to personalize our exercise plans
  • Questionnaires - Patients and their parents will be asked to complete quality of life and activity questionnaires

The Fetal Cardiac Program of the Labatt Family Heart Centre at The Hospital for Sick Children (SickKids) is made up of a multidisciplinary team that provides detailed evaluation, counseling and treatment for heart problems in the developing baby during pregnancy. We work closely with family doctors, midwivescommunity and high-risk obstetricians throughout Ontario, as well as geneticists and other pediatric subspecialistsWe partner with Mount Sinai Hospital to provide a range of fetal therapy through the Ontario Fetal Centre.  The Fetal Cardiac Program is a teaching program in affiliation with the University of Toronto. 

Heart problems in the developing baby may result from abnormal development of the heart (congenital heart disease), heart rhythm disturbances, complications from twin pregnancies, genetic conditions and health problems in the mother that affect the baby, including illness, medications and other exposures. 

The goals of the Fetal Cardiac Program are to ensure that families receive the highest quality of care for potential heart problems during pregnancy; to advance our understanding of the evolution of heart disease in the developing baby; and to provide ongoing educational support to families and providers alike.  We proudly serve as a local, national and international referral center for fetal cardiac care, research, and teaching.    

Learn about the Fetal Cardiac Program, including how to make a referral, clinic details, what to expect during a visit and more on our Clinic Directory.


Research is one of the foundations of the Fetal Cardiac Program. Many of the advances in imaging and care for babies with heart problems during pregnancy have come from research and particularly from the internationally renowned research team at SickKids. 

During your visit, you may be approached regarding participation in a research project. Participation in any research is voluntary and will not affect the care you and your baby receive at SickKids. 

Examples of current projects include: 

  • FAST and SLOW trial/registry to understand fast and slow fetal rhythm problems 
  • Maternal Hyperoxygenation and MATCH studies to assess the effects of acute and chronic oxygen delivery on heart and brain development 


The Fetal Cardiac Program provides on-going education to sonographers, fellows, cardiologists, obstetricians, radiologists, geneticists, nurses, midwives and other allied health practitioners involved in the prenatal diagnosis and management of pregnancies affected with or at risk of fetal cardiac conditions. 

Courses and Symposiums

We offer both a one-day basic course and a 3-days advanced symposium. Both courses are submitted for review to the Canadian Paediatric Society for CME/MOC credits and Sonography Canada for CPD/CME/ARDMS credits. 

The 1-day course provides information on normal cardiac anatomy, the recommended views to screen for major heart defects and those lesions that may be detected on a routine ultrasound examination. It is presented in an interactive format that encourages audience participation, including case presentations that allow individuals to test their knowledge level. 

The 3-days advanced symposium provides more in-depth review and discussion of advances in fetal cardiology and care of the fetal cardiac patient and family. Lecturers and participants include local, national and international experts in Fetal Cardiology, High-Risk Maternal Fetal Medicine, Prenatal Diagnosis/Medical Genetics, and other allied health practitioners with interest and expertise in caring for this population.

The Core Paediatric Cardiology program at SickKids is designed as a three-year comprehensive training program in academic paediatric cardiology. Trainee wellness and a safe inclusive learning environment are at the core of our program. Our program is recognized by both the Royal College of Physicians and Surgeons of Canada and the American Board of Pediatrics. We have transitioned fully to Competency by Design since 2020. Rotations are typically one month in duration.

Program structure 

First year

The first year of the program is focused primarily on clinical cardiology. Rotations include:

  • Inpatient cardiology
  • Cardiology consultations
  • Echocardiography
  • Electrophysiology
  • MRI/CT
  • Outpatient clinic
Second year

The second year of training incorporates rotations in the cardiac ICU and cardiac catheterization laboratory as well as additional training in the core disciplines of cardiology. Significant time is spent in research during the second year. Rotations include:

  • Cardiac ICU
  • Cardiac catheterization
  • Echocardiography (including transesophageal and fetal)
  • Electrophysiology
  • Heart function and transplant
  • Longitudinal outpatient clinic
  • Research (3 months)
Third year

The third year of training solidifies training in the core disciplines as well as giving autonomy to the trainee in ‘senior trainee’ roles. Again, significant time is dedicated to elective and research time. Rotations include: 

  • Inpatient cardiology (as a senior trainee)
  • Cardiac ICU
  • Echocardiography (including TEE, fetal, review)
  • Electrophysiology
  • Cardiac catheterization
  • Longitudinal outpatient clinic
  • Adult Congenital Cardiology (located in Toronto General Hospital)
  • Research/Elective (4 months)

On call 

In-hospital on call is a requirement of the training program. We have a 24+2 hour on call rule (PARO guideline) meaning that you will have the day off following your on call. Third year trainees participate in echo back up on call to provide support for new first year trainees (home call). An on call stipend is provided.


We have a robust system of assessment within the program with Competency Based medical education at the heart of our program.

  • Our program has fully transitioned to Competency by Design (CBD) since 2020. Training is divided into four stages: Transition to discipline, Foundations of discipline, Core of discipline and, finally, Transition to practice. Trainees are evaluated based on Entrustable Professional Activities (EPAs) and In-Training Assessment Reports (ITARs). The competency committee meets regularly and reviews each trainee progress and determines their suitability to progress to the next stage of training. A faculty advisor provides feedback to the trainee following these meetings.
  • Trainees from each year of core training are required to write the In-Training Examination of the American Board of Pediatrics at the beginning of each academic year. This gives candidates the opportunity to compare their knowledge with other individuals at the same level of training.
  • Electronic In-Training Assessment Reports (ITARs) are automatically sent to the rotation supervisor at the end of each rotation. After the supervising cardiologist completes the electronic evaluation form, it is forwarded to the trainee who will review and sign it on-line. Faculty meet to discuss the evaluations with the trainees upon completion of the rotation.
  • Participation in Annual OSCE. Provides an opportunity to prepare for the Royal College certifying examination as well as receive feedback as to how they compare to their peers.

We believe that strong mentorship is key to a successful residency and/or fellowship and successful career. Each trainee is paired with both a personal/career mentor and a research advisor. Your mentors will remain with you during the duration of the training program. The program director also serves to provide mentorship during semi-annual reviews and on ad hoc basis throughout your training.

The Division of Cardiology has a long history of research excellence and the training program encourages our trainees to get involved in research projects throughout the duration of their training. Dedicated research rotations occur in each year. A formal research curriculum has been incorporated into our academic half day to provide you with the foundational principles of research. Each trainee is assigned a research advisor.

A scholarship oversight committee provides additional guidance and mentorship around trainee's scholarly activity. The program provides funding for trainees to attend a scientific conference annually (because on occasion, they can attend more than one). There is an annual trainee research award awarded to a trainee who demonstrated excellence in scholarly work over the previous year. Dedicated research fellowships and innovation seed funding for research projects are available through a peer-reviewed process.

The training program has a strong history of providing excellent formal and informal educational opportunities. We offer a rich series of lectures in an academic half day setting, which is protected time from clinical duties. We routinely evaluate and update the content of our half day lecture series. Guest speakers from outside of the Division are regularly invited and examples of topics have included wellness strategies, feedback and coaching and teaching the teacher.

Outside of the academic half day setting, teaching occurs in multiple places that include:

  • Faculty delivered informal case-based discussions in cath, echo, CT/MRI
  • Professor rounds: Weekly in-depth discussions about challenging cases
  • Fetal teaching: Weekly multidisciplinary fetal teaching
  • Cardiovascular surgical teaching, offered in conjunction with Cardiovascular surgical trainees

We foster teaching excellence in our trainees and offer multiple opportunities for trainee led teaching. There is an annual teaching award given to both the core and subspecialty trainee who demonstrated commitment and excellence in education throughout the year.

Examples of trainee-led teaching include:

  • Core and subspecialty led daily teaching
  • Paediatric resident teaching
  • Annual cardiology PERLs sessions

Trainees attend weekly cardiovascular surgical rounds in which surgical or interventional strategies are made for patients with congenital or acquired heart disease. Weekly surgical performance rounds and monthly Mortality and Morbidity rounds are held for programmatic improvement.

This is our current teaching schedule.

The physical, psychological, and social wellbeing of our trainees is key to our success as a training program. We have a Wellness Committee made up of both faculty and trainees that strive to improve trainee wellness. Initiatives include:

  • Annual trainee retreat
  • Yoga and running clubs
  • Balint groups for debriefing after traumatic events
  • Strengthening our mentorship program
  • Establishing a wellness curriculum
  • Social events
  • Career evenings

Visit the Office of Postgraduate Wellness for additional wellness resources. 

What are equity, diversity, and inclusion?
  • Equity: equal access to treatment, opportunities, resources, and advancements
  • Diversity: acknowledging and embracing differences between people and ensuring fair representation
  • Inclusion: providing a safe and respectful space where all are welcomed and engaged
Why are they important?

Equity, diversity, and inclusion matter because the heart of this program are the people: residents, fellows, faculty, patients, and families. We strive to cultivate an environment where everyone feels comfortable being their true selves, where differences are respected and valued and where trainees are empowered to collaborate and share their ideas.

What is being done within the program to foster a culture of equity, diversity, and inclusion? 

As a training program that accepts trainees from all over the world, we welcome different perspectives as it is this diversity that drives innovation and growth. By recognizing, addressing, and minimizing bias and inequities, we are working to create a space that is open, supportive, and respectful.

A few examples of initiatives within our program:

  • Allyship Training
  • Hidden Curriculum Training
  • Implicit Bias Training

We offer a one-year subspecialty fellowship in advanced echocardiography. This fellowship is immersive in all aspects of clinical echocardiography. The echocardiography laboratory at SickKids performs 1,500 Transthoracic and 500 transesophageal echocardiograms each year.

Fellowship Highlights:

  • Gain expertise in transthoracic image acquisition, optimization, and interpretation for patients with both congenital and acquired heart disease
  • Develop skills in advanced imaging technologies such as strain imaging and 3D
  • Perform intraoperative transesophageal echocardiograms to assist in surgical decision making
  • Provide echo guidance for interventional catheterizations such as ASD device closure, VSD device closure, PDA device closure in preterm infants.
  • Present echo images at weekly cardiosurgical conference
  • Weekly echo staff physician delivered teaching
  • Participate in the teaching of core cardiology trainees and sonographers
  • Provide on call support for new core trainees
  • Learn and supervise exercise echo

The echocardiography lab at SickKids is a world leader in cardiovascular ultrasound research and our fellowship offers a unique opportunity for trainees to become involved in imaging research. We encourage our fellows to become involved in a research project during their clinical fellowship. Twice monthly echo research rounds are hosted and provide a forum for collaboration and learning. Opportunities to pursue a research fellowship following the clinical training exist.

Fetal Echocardiography Fellowship

The Fetal Cardiac Program in the Labatt Family Heart Centre offers a one-year comprehensive fetal fellowship for select candidates interested in a career in fetal cardiology. We are one of the largest fetal cardiac programs in the world with seven staff cardiologists and a team of dedicated nurses, sonographers, and administrative assistants. We perform more than 2,500 high-risk fetal echocardiograms per year and serve as a regional, national, and international referral centre.  

In addition to daily fetal clinics at SickKids, we have two daily clinics per week to perform first trimester fetal echocardiograms at Mount Sinai Hospital alongside our maternal-fetal medicine colleagues. Through the Ontario Fetal Centre, which is a collaboration between SickKids and Mount Sinai, we are the only program in Canada to offer percutaneous fetal cardiac intervention.  Additionally, we are one of few centres in the world to perform fetal cardiac MRI, both for clinical and research purposes. Our world-class Genetics team also provides unique opportunities for collaboration and teaching, as well as research avenues through the Cardiac Genome Clinic.

Fellows are exposed to all members of our multi-disciplinary team. There is an abundance of educational opportunities, including weekly case-based teaching; weekly provincial fetal cardiology rounds, which includes journal clubs, pathology rounds, and M&M conferences; and monthly multi-disciplinary perinatal rounds.  Beyond the clinical and educational offerings, fellows typically complete at least one research project during the year with our productive fetal cardiology staff.

The fetal fellowship is generously supported by the Policaro Family.

Electrophysiology Fellowship

The Pediatric Cardiac Electrophysiology program trains fellows to achieve excellence in all areas of pediatric arrhythmia management. Trainees develop expertise in the diagnosis and management of arrhythmias disorders in children with and without congenital heart disease. This will include invasive and noninvasive testing, as well as medical management, device implantation and management, and catheter ablation. 

PCEP fellows participate in both inpatient and outpatient settings learning to diagnose and manage the full breadth of electrophysiologic conditions. Fellows gain increasing responsibility while learning the management and natural history of a wide variety of cardiac arrhythmias. 

Fellows are involved in all EP procedures, and given increasing responsibility in the EP laboratory. Procedures include diagnostic EP studies and catheter ablation for supraventricular and ventricular tachycardias. They are involved in pacemaker, ICD, and cardiac resynchronization therapy device implantations both in the cath lab and in the operating room in conjunction with cardiac surgery for epicardial procedures. Fellows also participate in non-invasive procedures such as cardioversions and device tests. Fellows consult on patients with arrhythmias and implanted devices in the intensive care units and other inpatient units. 

In the outpatient arena, EP fellows spend a minimum of a half-day each week in one of the arrhythmia outpatient clinics, as well as covering the pacemaker clinic. The fellows rotate among each of the EP faculty clinics, thus affording trainees the opportunity to observe and manage patients longitudinally, and to gain experience with different management styles. They read ECG, exercise tests and Holter monitors under the guidance of the EP staff.

The fellowship is designed to provide trainees with a broad educational experience. In addition to the extensive direct clinical exposure, a variety of educational opportunities are provided during the fellowship. A weekly EP service meeting, attended by all EP faculty and fellows, is used for teaching, discussion of recent cases and complications, as well as upcoming cases in both the cath lab and the operating room. Outpatient consults and challenging cases are also brought to this forum for review and management planning. Fellows attend two monthly meetings on inherited arrhythmia, one reviewing internal cases and one reviewing shared families with our adult partners at Toronto General Hospital. Fellow also present teaching to core cardiology fellows and pediatric residents on a monthly basis.

Interventional Catheterization

Training in interventional cardiology at SickKids offers exposure to a full spectrum of interventional cases and complex patients. Working with a staff of four experienced interventionalists with somewhat unique areas of expertise, the trainee will gain fluency in technical skills and decision-making. Clinical responsibilities include pre- and post-cath care as well as procedural responsibilities. Research and teaching opportunities are available within the Division; the senior fellow typically takes on a leadership role for core trainees rotating through the lab. Adult congenital and structural exposure is available, if desired, through a collaborative experience at Toronto General Hospital.
