SIMULTANEOUS BIPLANE CORONARY AND PULMONARY ARTERIOGRAPHY - A NOVEL TECHNIQUE FOR DEFINING THE COURSE OF AN ANOMALOUS LEFT MAIN CORONARY-ARTERY ORIGINATING FROM THE RIGHT SINUS OF VALSALVA

We present a novel technique employing biplane cineangiography with si multaneous left coronary and pulmonary angiography to define the anoma lous course of the left main coronary artery when it originates from t he right sinus of Valsalva, These biplane cinearteriograms clearly def ine the relationship of the left main coronary artery to the great ves sels, allowing confident delineation of the interarterial Variant from the other, benign variants, We illustrate the advantages of this tech nique with two cases in which the course of the anomalous left main co ronary artery was incorrectly diagnosed using standard coronary arteri ography and magnetic resonance imaging.
