Popis: BackgroundExtended right coronary arteries are not uncommon in coronary surgery. They can be revascularized optionally either by conventional single or complete multiple bypassing. However, there are still no objective data showing the superiority or appropriateness of one of these methods over the other.MethodsExtended right coronary arteries were identified by preoperative angiographic scoring and randomized to multiple-bypassing (group A; n = 32) or single-bypassing (group B; n = 32) groups. Four parameters that show the completeness of right coronary territory revascularization were evaluated and compared between the 2 groups.ResultsAlthough overall perioperative ischemic events seemed to increase in the single-bypass group (P = .0059), half of them were reversible, and there were no statistical differences between the definitive perioperative ischemic event rates, namely, infarction rates, and the remaining 3 parameters of the groups. Logistic regression analysis showed that preoperative left ventricular dysfunction (ejection fraction
