Aortic valve replacement and coronary bypass in patients with severe stenosis of the left main coronary artery

Adequate myocardial protection is difficult to achieve during operations for combined aortic valve disease and severe stenosis of the left main coronary artery. A double cross-clamp technique, which facilitates the delivery of cardioplegic solution to the myocardium, is described here. We reviewed the experiences of 11 patients, 6 of whom underwent operation using the new technique.
