He has been involved in numerous clinical trials to advance the transcatheter treatment of congenital heart disease. His interests include non-surgical treatments of PDA in premature infants, ASD, VSD, fistulas, AV malformations, and valve disease, as well as treatment of various vascular obstructions and recanalization of occluded vessels. This has segued over the last few decades to include caring for patients with Adult Congenital Heart Disease (ACHD). He enjoys tackling challenging scenarios with innovative approaches. More recently, he has helped achieve more appropriate recognition of the work congenital interventional cardiologists do by becoming deeply involved in the national CPT and Relative Value Update process. He is currently focusing on ACHD interventions at IU Methodist Hospital.
