ANGIOGRAPHIC DETERMINATION OF VENTRICULAR MORPHOLOGY - CORRELATION WITH PATHOLOGY IN 36 HEARTS WITH SINGLE FUNCTIONAL VENTRICLES

Among 36 patients with univentricular atrioventricular connections, 27 had left ventricular and 9 right ventricular morphology, None had a c ommon or indeterminate ventricle on autopsy review, Angiographic analy sis correctly determined ventricular morphology in 34 (94%) of 36 pati ents. All 9 patients with right ventricular morphology of the dominant ventricular chamber were correctly identified angiographically. Altog ether 25 of 27 patients (93%) with left ventricular morphology of the dominate ventricular chamber were correctly identified angiographicall y. Two patients with left ventricular morphology and severely dilated ventricles were incorrectly classified as having right ventricular mor phology by angiographic assessment, For patients with a single functio nal ventricle, we conclude that angiographic assessment is an excellen t method for determining ventricular morphology.
