Minimally invasive direct coronary artery bypass (MIDCAB) utilizes a small (4–5 cm) left anterior thoracotomy incision for direct visualization of the diseased coronary artery on the anterior wall of the left ventricle without the use of cardiopulmonary bypass (CPB).

This article describes the basics of the MIDCAB surgery, emphasizing both the left anterior thoracotomy for the harvest of LIMA and direct anastomosis on a beating heart without CPB. This procedure is done on a 72-year-old patient who had significant long LAD stenosis and presented with effort angina. Following a multidisciplinary “heart team” conference, he underwent a successful MIDCAB and was discharged home on postoperative day 4.

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).
