    Dr. Puskas specializes in adult cardiac surgery, including aortic root surgery, and minimally invasive valve 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.
