Dr. John D. Puskas is Chair of Cardiovascular Surgery at Mount Sinai Saint Luke's, Mount Sinai Beth Israel and Mount Sinai West and also serves as Director of Surgical Coronary Revascularization for the Mount Sinai Health System.

Dr. Puskas specializes in adult cardiac surgery, including aortic root surgery, and minimally invasive valve surgery. He is internationally recognized for his expertise in off-pump coronary artery bypass surgery and began performing off-pump coronary bypass surgeries in 1996. In 1997, he performed the world's first triple off-pump bypass surgery using minimally invasive coronary artery bypass grafting. In addition to his extensive leadership in less invasive coronary bypass surgery, he is recognized for his work in all arterial revascularization strategies, and robotic coronary revascularization. He has been a pioneer in the development of minimally invasive surgical techniques for the treatment of atrial fibrillation.

Prior to joining Mount Sinai, Dr. Puskas served at Emory University School of Medicine in Atlanta as Chief of Cardiothoracic Surgery at Emory University Hospital Midtown, founding Director of the Clinical Research Unit and as Professor and Associate Chief of the Division of Cardiothoracic Surgery.

At Mount Sinai, Dr. Puskas will continue his pioneering work investigating the benefits of off-pump cardiac surgery, developing new surgical techniques, and testing the latest technologies in advanced clinical trials. He is currently the national principal investigator for three ongoing U.S. Food and Drug Administration investigational device trials and national principal investigator for the NIH-sponsored Hybrid Revascularization Trial, exploring novel approaches to the treatment of coronary artery disease by combining both minimally invasive robotic coronary bypass surgery and catheter-based stent therapies.

Dr. Puskas is a past president of the International Society for Minimally Invasive Cardiothoracic Surgery and a member of the American Association for Thoracic Surgery, American College of Chest Physicians, American College of Surgeons, International Society for Minimally Invasive Cardiothoracic Surgery, and Society of Thoracic Surgeons.

A summa cum laude graduate of Princeton University, Dr. Puskas received his medical degree from Harvard Medical School. He completed his residency in general surgery at Massachusetts General Hospital and his cardiothoracic surgery residency training at Emory University School of Medicine.
