Skilled Heart Surgeons

Leading the heart surgery team at Affinity Health System is Zenoun Abouzelam, MD. Dr. Abouzelam has been practicing all aspects of cardiovascular and thoracic surgery for Affinity Health System since 1989 and became medical director of Cardiothoracic Surgery in 2004. He has a special interest in minimally invasive cardiac surgery (MICS) for valvular heart disease, mitral valve repair, thoracic aortic surgery, and carotid endarterectomy. Dr. Abouzelam is a diplomate of the American Board of Surgery and American Board of Thoracic Surgery. He trained at Yale University and the Medical College of Wisconsin.

Dr. Abouzelam was the first in Northeast Wisconsin to perform minimally invasive aortic and mitral valve surgery to facilitate faster patient recovery.  For the year 2011-2012 he is the single busiest heart surgeon in the state of Wisconsin.

Subhasis Chatterjee, MD, has been in practice since 2009. He provides personalized care to adults with valvular heart disease, coronary artery disease, atrial fibrillation and aneurysms of the thoracic aorta. Dr. Chatterjee is certified to perform minimally-invasive valve surgery. Dr. Chatterjee is also a diplomate of the American Board of Surgery and American Board of Thoracic Surgery. He trained at the University of Pennsylvania, Cornell University, Memorial Sloan-Kettering Cancer Center, and the Vanderbilt Heart Institute.

Dr. Chatterjee was on the faculty at the University of Chicago and was actively involved in the landmark transcatheter aortic valve replacement trial. He looks to develop advanced valve therapy programs.

Minimally Invasive Valve Replacement

Dr. Abouzelam at St. Elizabeth Heart Hospital was the first in Northeast Wisconsin to offer minimally invasive valve surgery as an alternative to traditional heart surgery. This technique uses a smaller three-inch incision resulting in less blood transfusions,  shorter hospital stay and faster recovery than the standard six- to-nine-inch incision, which completely divides the breastbone. Patients can be back to normal activities just two to four weeks after surgery, compared to six or eight weeks. 

Valve Repair

"It’s well-established that mitral valve repair when feasible leads to improved long-term survival compared to replacement," says Dr. Chatterjee. 

Dr. Abouzelam adds, "The national rates of valve repair are about 58 percent. At Affinity we repair almost 70 percent of all mitral valves, which puts us amongst the leaders in the state."

Excellent Results

Over the last two years, compared to the national results for coronary bypass grafting of 2 percent mortality and 1.2 percent stroke rate, our results at Affinity demonstrate a 1.5 percent mortality and a 0 percent stroke rate. This is further reinforced by the number of high-risk patients seen each year who were turned down for surgery at other regional programs.

Cardiac Rehabilitation

After your heart surgery, you’ll receive inpatient rehabilitation as soon as your physical condition allows. Cardiac rehabilitation specialists will teach you a variety of heart strengthening exercises. They also provide emotional and educational support to you and your family, and suggest possible lifestyle changes including nutrition, exercise and weight control.
