91ɫƵ Pediatric Cardiology Fellowship
The pediatric cardiology fellowship within the Herma Heart Institute (HHI) provides superior training in one of the nation's largest pediatric cardiology, cardiac surgery and cardiovascular research centers.
Our objective is to prepare fellows for careers within academic or non-academic pediatric cardiology. Pediatric cardiology training will focus on excellence in clinical skills, understanding of hemodynamics and pathophysiology and an appreciation for natural history. It is a goal of the fellowship to give trainees exposure to all aspects of cardiology while providing an appropriate balance of autonomy and advanced learning with our clinicians. Three years of training is required for the sub-board of pediatric cardiology and a fourth year of advanced clinical/research training is available at our center.
