Dr. Puskas specializes in adult cardiac surgery and is internationally recognized for his expertise in off-pump coronary artery bypass surgery. He began performing off-pump coronary bypass surgeries in 1996, and in 1997 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.
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 that will now move with him to Mount Sinai.
