Single coronary artery: a familial clustering.
A 59 year old man undergoing investigation for chest pain was found at elective coronary angiography to have a single coronary artery; the left coronary had a normal distribution, with the right coronary originating as a continuation of the atrioventricular circumflex. His 30 year old daughter was admitted for elective coronary angiography for further investigation of a dilated cardiomyopathy. She was also found to have a single coronary artery. However, in her case, the right and left coronary arteries arose from the right sinus of Valsalva; the right coronary had a normal distribution, the left coronary passed anterior to the pulmonary trunk and aorta.
