Anomalies of aortal origin of the coronary vascular system are found in approximately one percent of the population and can be exactly documented by coronary angiography. Although such variants of origin and in the coronary vascular course are not associated with an increased incidence in coronary sclerosis, it is important that they be known for several reasons: 1. in order to avoid false interpretations of the coronarogram that can be of grave consequence, 2. for the selection of the correct incision at heart surgery, 3. a very rare anomaly, the origin of the trunk of the left coronary artery in the right Valsalva's sinus, is clearly related to sudden cardiac death in children and youths. A correct diagnosis can be life-saving.
Two patients with chest pain had angiographically-demonstrated communications between the three coronary arteries and the left ventricular chamber. Communications between coronary arteries and the left ventricle are unusual and communications between all three coronary arteries and the left ventricle are rare. These anomalies are, however, commonly associated with symptoms of chest pain. The presence of left ventricular hypertrophy and a widened pulse pressure may suggest a greater hemodynamic effect of the shunt flow than often suspected angiographically.
