Cardiothoracic Surgery

Open-heart Surgery in the Hudson Valley 

Garnet Health is your home for comprehensive cardiac care - and the first heart surgery program in Orange County, New York - from diagnosis, to medical and surgical treatment, and to recovery and rehabilitation.

Garnet Health Medical Center's open-heart surgery program is led by Medical Director Michael Argenziano, MD, FACS, recognized as one of New York Magazine's Top Doctors. Dr. Argenziano also serves as associate chief of the Division of Cardiac, Thoracic, and Vascular Surgery at NewYork-Presbyterian/Columbia University Irving Medical Center.

In addition to Dr. Argenziano, our team boasts the expertise of cardiothoracic surgeon Mariano Brizzio, MD, who serves as our Site Director, and cardiothoracic surgeon Saqib Saeed, MD. Together, these three surgeons form the core of our leading open-heart surgery team, performing a multitude of invasive and non-invasive heart procedures. Collectively, this team of highly skilled and talented cardiothoracic surgeons embodies over 50 years of experience, having successfully performed more than 11,000 cardiothoracic surgeries.

Through our partnership with NewYork-Presbyterian/Columbia University Irving Medical Center, our specialized and advanced care teams, and our new state-of-the-art operating rooms, we give our local community access to advanced cardiothoracic surgery procedures that don't require patients to travel to New York City. This partnership allows local residents to receive the same expert heart surgery procedures as those performed in New York City, while staying close to home.

In October 2023, we cut the ribbon for our new hybrid surgical suite located at Garnet Health Medical Center. This new hybrid OR is state-of-the-art and equipped with the most advanced medical imaging technology including MRI and CT allowing surgeons to perform open and minimally invasive procedures. Its infrastructure includes a control room and is designed for performance, flexibility and reliability. The opening of a second operating room for cardiothoracic procedures offers more life-saving capacity to care for our patients experiencing cardiac related issues.
