Get to know Cardiothoracic Surgeon Dr. Allan Stewart, who serves patients in Miami, Florida.

Dr. Allan Stewart is a highly accomplished cardiothoracic surgeon specializing in minimally invasive cardiac surgery. With extensive experience in performing TAVR procedures, he was one of the first to perform this procedure in the United States. He also specializes in valve-sparing aortic root procedures, a procedure he has performed throughout the world. 

His journey towards becoming a renowned cardiac surgeon began at a young age. Inspired by an episode of NOVA on public television, he made a life-changing decision to dedicate himself to surgery on people’s hearts when he was just eleven years old. Driven by his passion, he embarked on a rigorous training path that would shape his illustrious career.

After graduating with his medical degree from Rutgers University School of Medicine, Dr. Stewart started as an intern in general surgery at the Hospital of the University of Pennsylvania, where he underwent seven years of training, including two years studying human gene therapy. His unwavering commitment and exceptional aptitude led him to specialize in cardiac surgery at Columbia University Medical Center. He not only completed his specialization but also continued his journey as a faculty member, delving into advanced training in heart transplant and artificial heart surgery. In recognition of his expertise, he was appointed as an Assistant Professor, where he served from January 2005 until November 2013.

During his tenure at Columbia University, his talents were recognized, and he was entrusted to lead the Center for Aortic Disease at Mt. Sinai Hospital in New York. He was promoted to the rank of Associate Professor of Cardiovascular Surgery and additionally served as the Medical Director for Mount Sinai International.

Seeking to make a more significant global impact, Dr. Stewart made a bold move to Miami, where he assumed the role of Medical Director and Chief of Cardiac Surgery at HCA Healthcare East Florida Division in 2019. Committed to creating a destination for cardiovascular disease in Miami that would impact Latin America and the Caribbean, he wasted no time in establishing structural heart programs in three Dade County Hospitals and the Dade County Aortic Emergency Reference Center.

On a professional level, he is an active member of the American Association of Thoracic Surgeons, the Society of Thoracic Surgeons, the American College of Surgeons, and the American College of Cardiology. His sub-specialty in aortic surgery and transcatheter valves has propelled him to produce a substantial body of work. He has authored over 50 manuscripts and book chapters, firmly establishing himself as a respected authority in his field.

Notably, Dr. Stewart has been involved as a principal investigator in numerous clinical trials, including pivotal ones like PARTNER I, II, SURTAVI, SENTINAL, Bolton RELAY, and THORAFLEX HYBRID. Driven by his thirst for knowledge, he enrolled in and graduated from the inaugural class of the Surgical Leadership Program at Harvard Medical School in 2019, ensuring he stays at the forefront of surgical innovation and leadership.

Defining himself primarily as a teacher, he takes pride in training numerous physicians in aortic surgery, many of whom hold prestigious positions worldwide. Eleven of his trainees currently hold the esteemed title of Director of Aortic Surgery in various departments throughout the United States, Japan, and Israel.

Dr. Stewart’s remarkable achievements have not gone unnoticed by the media. He has been featured as a surgeon in the medical documentary “NY MED” and has made appearances on several prominent shows, including the Rachael Maddow show, Fox News, Good Day NY, and the Today show. His expertise and contributions have been documented in publications like the New York Times and the New York Daily News. Furthermore, his inspiring journey and remarkable career have been captured in the book “Barefoot in New York.”

Cardiothoracic surgery is the field of medicine involved in the surgical treatment of organs inside the thorax. Cardiothoracic surgeons are medical doctors who specialize in surgical procedures inside the thorax, which may involve the heart, lungs, esophagus, and other organs in the chest. Alongside performing surgery, they also diagnose and treat diseases of these organs.

Having performed surgeries on six continents, spanning 21 countries, Dr. Stewart has been honored in Castle Connolly’s Best Doctors in America and New York Magazine’s Best Thoracic Surgeons. For the past eleven consecutive years, he has been included in the Most Honored Doctors list.
