The Department of Surgery is pleased to announce that pediatric cardiothoracic surgeon Lloyd “Mac” Felmly, M.D. has joined the Division of Pediatric Cardiothoracic Surgery, where his expertise will help enhance the division’s clinical programs, and he will help develop and lead the pediatric lung transplant program. Dr. Felmly has experience in all areas of pediatric and congenital heart surgery, including neonatal and infant heart surgery, aortic and mitral valve repair, the treatment of coronary anomalies, double switch operations for patients with congenitally corrected transposition of the great arteries and other complex disorders, and heart and lung transplantation.

Dr. Felmly attended both medical school and surgical residency at the Medical University of South Carolina. During his I-6 cardiothoracic surgery residency, he was recognized for excellence, receiving both the William H.

Following his MUSC surgical training, he completed a prestigious 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. This fellowship featured an additional focus on Tetralogy of Fallot and pulmonary atresia. With this experience Dr. Felmly specializes in procedures to create new pulmonary arteries in patients with major aortopulmonary collaterals and to relieve blockages in pulmonary arteries due to peripheral pulmonary stenosis.

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 numerous peer-reviewed journal articles and book chapters. His research interests include studying the clinical outcomes of patients undergoing operations for complex pulmonary artery abnormalities.
