Lindsey Saint, MD, is a Fellow of the American College of Cardiology who specializes in complex conditions that prevent the heart and vascular system from circulating blood normally. She is a board-certified general and cardiothoracic surgeon, and performs transcatheter, minimally-invasive and surgical heart valve repair and replacements; aorta and aortic root reconstruction; coronary artery bypass grafting and more.

Dr. Saint was influenced to become a doctor after her father was in a car accident, and his spine surgeon helped her dad relieve his pain and returned his ability to play with his children. Heart conditions can be scary, and she wants every patient and their family to feel comfortable during an otherwise highly stressful and anxiety-provoking time in their lives by answering their questions and empowering patients as a partner to create a plan that best fits with their overall health, lifestyle and goals of treatment.

In her free time, Dr. Saint has a busy life with her husband, four kids, two energetic dogs and two apathetic cats. When it’s warm out the Saint family is at the pool or enjoying live music, while in winter they watch movies by the fire or ski.
