Aberrant origin of the left coronary artery from the proximal right coronary artery: diagnostic features and pre- and postoperative course.

In this report, we present the pre and late postoperative course of a patient with severe angina secondary to aberrant origin or the left coronary artery from the proximal righ coronary artery (Fig. 1). We illustrate the noninvasive diagnosis and evaluation of this patient by two-dimensional ultrasound and stress thallium imaging, and the pre and late postoperative angiographic and thallium perfusion findings.
