| pubmed-article:6824409 | pubmed:abstractText | After undergoing a ligation of the anomalous left coronary artery from the pulmonary artery and a saphenous vein bypass graft surgery, a 53-year-old woman has had improvement in exercise tolerance and congestive heart failure for up to two years of follow-up. Comparison of the preoperative and postoperative noninvasive studies disclose that surgery improved the left ventricular volume overload and perfusion. However, there was no change in the resting or exercise ejection fraction as assessed by stress multiple-gated acquisition isotope scan. | lld:pubmed |
