Khanh H. Nguyen, MD, Professor and Chief of Pediatric Cardiothoracic Surgery, was featured in Inside Mount Sinai for his recent visit to The Hue Central Hospital in Hue, Vietnam, his birthplace.  Dr. Nguyen is building a partnership with The Hue Central Hospital, helping young patients receive advanced care and training local surgeons on cutting edge surgical procedures.  Accompanying Dr. Nguyen on his trip was David H. Adams, MD, the Marie-Josee and Henry R. Kravis Professor and Chairman of the Department of Cardiothoracic Surgery. Find out more in Inside Mount Sinai.

As Chief of the Division of Pediatric Cardiac Surgery, Dr. Nguyen is intimately involved with and oversees all aspects of the program which is one of only a few in the tri state area capable of performing the complete spectrum of pediatric cardiovascular surgical operations including heart transplantation from the premature neonate to the adult with congenital heart disease.  Working in conjunction with the ICU staff, he implements new protocols for care of patients in the Pediatric Cardiac Intensive Care Unit and has been instrumental in reducing the length of stay in the unit.

Dr. Nguyen has established himself as one of the premier pediatric cardiovascular surgeons in the United States performing the most complex of pediatric cases with one of the lowest mortality rates in the United States.   He performed the first implantation of a cardiac assist device in a child in the tri state area. As a surgeon, he has performed more than 2,500 operations.  He is also treats adult patients with congenital cardiac disorders, whose open heart operations require expertise in both adult and pediatric cardiac diseases.  The pediatric cardiac program at Mount Sinai   is the first and only one in the country in using invisible axillary incisions in minimally invasive surgery to repair congenital cardiac disease. This approach has also been used in adult male and female patients with great cosmetic success.

Dr. Nguyen has published several peer review articles which have appeared in the Journal of Thoracic and Cardiovascular Surgery, Pediatric Cardiology and The Annals of Thoracic Surgery.  He has also been invited to speak at numerous forums. He is the Primary Investigator on several research projects including the use of the pulmonary valve in replacing the mitral valve, the use of an extracellular matrix patch to reconstruct the aortic valve to obtain a long term outcome in growing patients and also the use of the Berlin Heart for refractory heart failure in children.  This protocol provides the framework for the compassionate use of a non-approved FDA device used as a bridge to transplant.

Dr. Nguyen has led many surgical missions to other countries including Romania, China, Honduras and Vietnam.  In 2009 he returned to Vietnam and performed 15 open heart procedures in infants and children.  Some of the procedures were highly complex, including an Arterial Switch operation and repair of an Epstein's anomaly.

Dr. Nguyen received his medical degree from the University of California College of Medicine at Irvine. He completed his residency in cardiothoracic surgery at The Mount Sinai Medical Center and followed that with pediatric cardiac surgical training at The Great Ormond Street Hospital for Children in London.
