After experiencing chest pressure while exercising, a 72-year-old patient tested positive in both a stress test and nuclear medicine study, triggering a left heart catheterization that revealed a high grade lesion of the proximal left anterior descending coronary artery. His cardiologist determined the lesion would not be amenable to angioplasty or stenting, so Dr. Marco Zenati performs a minimally invasive coronary artery bypass (MIDCAB).

In this long and complicated case, Dr. Marco Zenati performs a full, biatrial Cox-MAZE IV procedure with coronary artery bypass grafting (CABG) and a mitral valve replacement (MVR), moving between the three procedures as necessary to minimize time on the ischemic heart. The patient suffers from congestive heart failure that recently escalated from class II to class III.
