title: Selective right ventricular dysfunction after coronary artery bypass grafting.
abstract: Preoperative and postoperative right (RVEF) and left ventricular ejection fractions (LVEF) were studied by means of radionuclide techniques in 15 patients undergoing coronary bypass operations. Three of them, all with right coronary artery lesions, had postoperative depression of RVEF without concomitant decrease in LVEF. In contrast to those with left ventricular dysfunction, the patients with selective RVEF depression did not have significant elevation of myocardial injury index calculated from creatine kinase isoenzyme (CK-MB) curves.
