Biography

Dr. Marshall is a patient-focused paediatric cardiologist who pursues diagnoses and treatments through interventional catheterization.  Her extensive training and experience have led to her recognition as a leader in the field of invasive cardiology for congenital heart disease, and fetal cardiac intervention.   

Born and raised in the American Midwest, she pursued her education and medical training at institutions including Yale, the University of Pennsylvania, and the Harvard-affiliated Boston Children’s Hospital.  At Boston Children’s, she led the cardiac catheterization laboratory, providing interventional consultation both locally and nationally, and performing 300 procedures a year.  In practice for over 20 years, she has provided cardiac care to some children and their families throughout the course of childhood. She is a mother of three, and an advocate for children with complex healthcare needs.

Research

Dr. Marshall’s current clinical research interests focus on the areas of:

  1. Outcomes and complications of interventional catheterization procedures in congenital heart disease (CHD)
  2. New technologies and devices used in management of CHD
  3. Diagnosis and intervention for prenatally-diagnosed CHD

Dr. Marshall hopes to collaborate with the very active fetal diagnostic and interventional group within the heart centre at SickKids. Also, with her team's participation in a North American registry of paediatric interventional catheterization procedures, she intends to work with colleagues at other centers reporting multi-center outcomes of the procedures included. With regard to new devices/technologies, Dr. Marshall aims to resume investigation of an implantable hemodynamic monitoring system which would allow real-time availability of invasive circulatory measurements in the management of patients with CHD. This is a device that has won regulatory approval for use in heart failure management but has not yet been adopted for use in paediatric patients.
