Biography

    About Allan S. Stewart, MD
    Allan S. Stewart, MD is Director of Aortic Surgery and Co-Director of the Valve Center in the Department of Cardiothoracic Surgery at The Mount Sinai Hospital, and also serves as Associate Professor in the Department of Cardiothoracic Surgery at Icahn School of Medicine at Mount Sinai. Dr. Stewart joined Mount Sinai in 2013.
     
    As an experienced cardiac surgeon, Dr. Stewart has performed more than 2,000 combined elective and emergency procedures in his career, including 1,000 heart valve operations. He specializes in the treatment of aortic valve disease through surgical aortic valve repair, aortic reconstruction, aortic valve-sparing surgery, aortic root replacement, aortic aneurysm repair, aortic dissection, transcatheter aortic valve replacement, and mechanical aortic valve replacement. Additionally, his clinical research focuses on creating and testing novel treatments and technologies for aortic valve repair and patient mechanical circulatory management during complex aortic surgery. He has published approximately 30 peer-reviewed research publications.
     
    As a heart surgeon, Dr. Stewart's goal is always to develop new ways to treat structural heart disease more minimally invasively, while increasing patient survival, improving patient outcomes, delivering more long-lasting, durable surgical results, while decreasing overall costs. Dr. Stewart pioneered a novel technique in stentless biological aortic root replacement. Also, Dr. Stewart developed a novel hybrid endovascular procedure for minimally invasively performing aortic repair, aortic replacement, and treating complex aortic aneurysms.
     
    Dr. Stewart is a member of American Association for Thoracic Surgery, Alpha Omega Alpha Honor Medical Society, American Heart Association, New York Society of Thoracic Surgery, Society of Thoracic Surgeons, American College of Surgeons, and National Marfan's Foundation.
