Abstract
An under tension graft to the right coronary artery may result in graft spasm, hypoperfusion and myocardial infarction. We suggest plication of the right atrium in order to confront the under tension graft (either arterial or venous), if tension is due to a shorter (up to 2 cm) graft than one needed. We present this technique applied to 10 of our patients. The radial artery was the under tension graft in two cases and a saphenous vein in eight. Perioperative and postoperative arrhythmias, myocardial infarction, hemorrhage and jugular or hepatic congestion were not observed. Central vein pressure remained normal. Tricuspid valve--estimated by postoperative echo--was undisturbed. Plication of the right atrium in case of an under tension graft is a quick, simple and safe technique.
