Ralph S. Mosca, MD, a pioneering pediatric cardiac surgeon who serves as chief of the Division of Pediatric and Adult Congenital Cardiac Surgery and director of the Congenital Heart Center at NYU Langone, has been appointed chair of the Department of Cardiothoracic Surgery at NYU Grossman School of Medicine. Dr. Mosca took the reins on January 1, 2022, from Aubrey C. Galloway, MD, the Seymour Cohn Professor of Cardiothoracic Surgery, who led the department for 15 years. Dr. Galloway will remain on the faculty and continue his clinical practice and research in complex valve repair and replacement surgery, as well as continue as the director of the Mitral Valve Repair Program.
Dr. Mosca, the Henry H. Arnhold Chair of Cardiothoracic Surgery, who has appointments in both the Departments of Cardiothoracic Surgery and Pediatrics, joined the faculty of NYU Grossman School of Medicine in 2009 from NewYork-Presbyterian Hospital. While there, he was as the first director of the Pediatric Cardiac Surgery Program at the Morgan Stanley Children’s Hospital.
A renowned congenital heart surgeon, Dr. Mosca has performed more than 6,000 open heart surgeries and helped define the modern-day surgical standard of care for hypoplastic left heart syndrome. He specializes in the surgical treatment of the most complex congenital heart defects in patients ranging in age from neonates through adulthood.
Under his leadership, the Pediatric Congenital Heart Program at Hassenfeld Children’s Hospital at NYU Langone became a national leader in pediatric and congenital cardiac surgery. Nearly 250 operations are performed annually, and the program has the highest risk-adjusted survival rate of any hospital program in New York State for pediatric patients, according to statistics from the most recently validated Society of Thoracic Surgeons database, which covers the 4-year period from July 2015 to June 2019.
“Dr. Mosca is a remarkable surgeon who works with patients and families at one of the most challenging moments in their lives,” says Robert I. Grossman, MD, dean and CEO of NYU Langone. “Under his leadership, the Department of Cardiothoracic Surgery will continue to provide specialized, world-class care for the most complex conditions.”
“We thank Dr. Galloway for his contributions and leadership of the department. During his time as chair, the department recruited national leaders in every subspecialty of cardiac and thoracic surgery, developed numerous new programs, and tripled the clinical volume,” says Dr. Grossman. “His commitment to patients, his faculty, and trainees embodies the exceptionalism that is required to be a remarkable physician and outstanding leader.”
