Heart Center of Greater Waterbury In the Greater Waterbury area, residents benefit from having advanced cardiac care available at not just one but two local hospitals they know and trust - Saint Mary's Hospital and Waterbury Hospital. Saint Mary's Hospital and Waterbury Hospital have partnered to offer the full complement of cardiac services, including angioplasty and open heart surgery at each of their facilities - the two campuses of the Heart Center. Cardiac services are provided at both campuses by the same clinical team of local, experienced, caring cardiologists and cardiothoracic surgeons. Our physicians work closely with specially trained nurses, technicians and hospital staff to provide individualized care to each patient and support for the patient's family. For prevention of cardiac disease, diagnosis, treatment and rehabilitation after cardiac procedures, the Heart Center of Greater Waterbury provides quality advanced cardiac care services close to home, the way it should be.
