Research Interests

Through the years, a distinct line in Dr. Coceani's research has focused on perinatal physiology and medicine, with specific interest on vascular shunts (i.e., ductus arteriosus and ductus venosus) and the pulmonary circulation. The approach constantly had a translational underpinning, with a special reward deriving from the study of vasoregulatory mechanisms in the ductus arteriosus. This research has led to the use of prostaglandin as a life-saving tool for neonates with congenital heart malformations and, more generally, to the pharmacological manipulation of the duct for therapeutic purposes.

Current interests deal with myocardial cell manipulation as adjuvant to antenatal corrective cardiac surgery. Collaborative work is also in progress with colleagues at SickKids on the role of the ductus venosus in the compensatory adjustments to intrauterine growth restriction and hypoxic insult.
