title: Isolated congenital absence of coronary sinus.
abstract: A case is reported in which contrast angiography showed complete absence of the coronary sinus, the cardiac veins draining separately into left and right atria. Normal systemic venous drainage was demonstrated by contrast cross-sectional echocardiographic methods and later confirmed by conventional angiographic injections. In addition, angiography showed a stenosis in the anomalous cardiac vein draining into left atrium accounting for the presence of a continuous murmur for which the patient was initially referred.
