Lloyd McPherson Felmly, MD

Dr. Lloyd M. Felmly is a pediatric cardiac surgeon specializing in repairing congenital heart defects. He was born in New York City, NY, and grew up in Columbia, SC. He graduated from medical school at the Medical University of South Carolina (MUSC) in 2015. He then completed post-graduate training in cardiothoracic surgery, also at MUSC. Following this, he completed two years of pediatric cardiac surgery subspecialty fellowship at Stanford University under Dr. Frank Hanley. There he learned to care for some of the most complicated congenital defects in the world and developed a strong interest in pulmonary artery reconstruction and complex biventricular repair.

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.

Dr. Felmly is a member of the Society of Thoracic Surgeons and has given numerous presentations at national and regional meetings. 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.
