Advanced Expertise

Leading the heart surgery team 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.

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

"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." says Dr. Abouzelam.
