"Dr. Michael Argenziano"Garnet Health’s award-winning Peter Frommer, MD Heart Center proudly announces the opening of its new open-heart surgery program in partnership with New York-Presbyterian/Columbia University Irving Medical Center. The first program of its kind in Orange County, complex cardiothoracic procedures can now be performed locally, allowing patients to receive expert heart surgery care without the stress of traveling far from their loved ones.
The program is led by cardiothoracic lead surgeon and Medical Director Michael Argenziano, MD, FACS, who also serves as associate chief of the Division of Cardiac, Thoracic, and Vascular Surgery at New York-Presbyterian/Columbia University Irving Medical Center. “In my nearly 30 years of being a cardiothoracic surgeon in New York City, I have performed open-heart surgery on many residents living in Orange and Sullivan Counties who needed to travel simply because there were no better options nearby,” said Argenziano. “Now, the same exceptional care you expect and receive in New York City is available right here.”
“Heart disease is a leading cause of death in both Orange and Sullivan Counties,” explained Rose Baczewski, Vice President & Chief Operating  Officer at Garnet Health, and the executive sponsor for the cardiothoracic surgery program. “And, while Garnet Health is already an award-winning heart care organization and recognized for our experienced cardiologists, as well as our specialists and advanced technologies, we knew we could do more to help our community. Adding open-heart surgery services truly elevates our ability to provide comprehensive cardiac care. ”
"Rosemary Baczewski"The open-heart surgery program at Garnet Health boasts new, state-of the-art operating rooms and equipment, and an exceptional team of cardiac experts. “The launching of this program fills such a vital need in our community and would not have been possible were it not for the dedication and hard work of our clinical team,” said Baczewski.
