Local immobilization of the left anterior descending artery for minimally invasive coronary bypass grafting.

We describe a device for coronary artery stabilization during minimally invasive coronary artery bypass grafting performed without cardiopulmonary bypass via a small (8 to 10 cm) left anterolateral thoracotomy. This device facilitates the anastomosis of the left internal mammary artery to the left anterior descending coronary artery on the beating heart. The device consists of a simple coronary stabilizer mounted on a wound spreader. We have used this device successfully in 35 primary minimally invasive coronary artery bypass grafting operations.
