Dr. Steve Xydas is Chief of the Columbia University Division of Cardiac Surgery at Mount Sinai Medical Center. He also serves as the co-director of South Florida’s only Aortic Center, at Mount Sinai, leading a multidisciplinary team cardiac and vascular surgeons specializing in complex aortic conditions.
Beyond his clinical work, Dr. Xydas has been involved with the Marfan Foundation, a non-profit organization that promotes the research and treatment of Marfan syndrome and other related disorders, since 2017. He has served as Medical Co-Chair for the Foundation’s South Florida Walk for Victory, raising awareness and funds of more than $1 million for genetic aortic and vascular conditions. In 2019, he initiated the MSMC Marfan Symposium as a vital platform for patients and families to access support and information. Dr. Xydas’ commitment to advancing patient care and community advocacy exemplifies his leadership in both medicine and in the community.
“Our partnership with the Marfan Foundation has been very fulfilling, seeing more and more Marfan patients and families seek out Mount Sinai for their family’s medical care needs,” Dr. Xydas explains. “It is very gratifying to see the difference you can make as a surgeon and physician when the magnitude of your impact is amplified across an entire family of affected individuals.”
