Finding the LAD during MIDCAB operations

Minimally invasive direct coronary artery bypass (MIDCAB) is a new surgical procedure that revascularizes the left anterior descending coronary artery (LAD) without the need for a median sternotomy or cardiopulmonary bypass. This operation is performed through a small left anterior thoracotomy. With this exposure, it can be difficult to locate the left anterior descending coronary artery. We have identified anatomic features on the surface of the pericardium that can serve as a landmark for finding the left anterior descending coronary artery.
