Dr. Felmly's clinical interests include neonatal and infant heart surgery, with an emphasis on Tetralogy of Fallot and pulmonary atresia. He specializes in procedures to create new pulmonary arteries in patients with major aortopulmonary collaterals (MAPCAs) and to relieve blockages in pulmonary arteries due to peripheral pulmonary stenoses (PPAS). He also has significant experience in aortic and mitral valve repair, heart and lung transplantation, the treatment of anomalous coronary arteries, and double switch operations for patients with congenitally corrected transposition of the great arteries (CCTGA), and other disorders such as heterotaxy.

Additionally, he has authored many peer-reviewed journal articles and book chapters. His research interests include studying the clinical outcomes of patients undergoing operations for complex pulmonary artery abnormalities.
