Why Choose Mount Sinai?

Mount Sinai Heart is recognized worldwide for its surgical treatment of aneurysms – a leading cause of death and disability. The Department of Cardiovascular Surgery at The Mount Sinai Health System has had a longstanding interest in the disease and surgery of the thoracic (chest) and thoracoabdominal aorta, as the first series of aortic arch operations was published in 1975 by Randall B. Griepp, MD. Our distinguished team, led by Allan Stewart, MD, continues this tradition of research and advanced care, focusing on all aspects and stages of aortic aneurysms. This has translated to significant benefits for patients, as the outcomes of aortic surgery at Mount Sinai Heart have consistently been the benchmark for other programs worldwide.

Aortic Aneurysm Surveillance Program

One of the first of its kind, the Aortic Aneurysm Surveillance Program at Mount Sinai Heart upholds a stringent monitoring program for patients with thoracic aortic aneurysms. This innovative Program includes imaging (i.e. CT scans) performed at regular intervals, three-dimensional reconstructions of the aorta developed from the images to compare growth in diameter and volume, and analysis to assess changes in the aortic aneurysm and treatment.

Throughout the Department's history, our teams of cardiac surgeons, anesthesiologists, and research scientists have reported their findings on all aspects of our Program, with a focus on efforts to better understand spinal cord and brain physiology as it relates to aortic treatment and surgery. These research efforts and our multidisciplinary approach have optimized clinical outcomes, as we bridge together our expertise in preoperative surveillance, surgery, and advanced critical care in the preoperative period, followed by comprehensive postoperative care.
