ABSTRACT

An adult with anomalous origin of the left coronary artery (originating from the pulmonary artery) had implantation of the anomalous vessel into the aorta. Exercise myocardial perfusion imaging with thallium-201, performed before and after the operation, disclosed a marked improvement in anterior-wall Tl-201 uptake. Postoperative isotope ventriculogram showed improved regional contraction in the revascularized anterolateral wall of the left ventricle. Thus, it has been demonstrated that implantation of an anomalous left coronary into the aorta improves regional myocardial perfusion and regional left-ventricular motion.
