RESUMO
Forty-nine patients have undergone combined aortic valve replacement and aortocoronary saphenous vein bypass graft surgery using a technique of distal coronary perfusion. Vein grafts are placed before replacement of the aortic valve, and continuously perfused by siting the proximal anastomoses high on the aortic root or individually perfusing the grafts before proximal anastomosis. Continuous coronary ostial perfusion is used as well during aortic valve replacement. There were 3 (6.1%) operative deaths and 1 (2%) perioperative myocardial infarction. A comparison of this technique with other reported results suggests that attention to myocardial perfusion distal to significant coronary artery stenosis may decrease the incidence of perioperative myocardial infarction in patients requiring both aortic valve replacement and coronary bypass graft operation.
