“…The patency of the main arterial segment is rather curious, as a blindending vessel would be expected to thrombose and obliterate. 16 We can offer no explanation for this, but we do not consider that this finding invalidates a congenital aetiology. Musiani and his colleagues 20 maintained that, in true congenital atresia of the left coronary artery, there is no coronary orifice and no left main trunk, with blind proximal ends to the anterior descending and the circumflex arteries.…”

“…Acquired stenosis of a coronary artery, or its orifice, is generally associated with more widespread arterial disease. [14][15][16] Congenital cases may rarely be associated with localised or widespread supravalvar aortic stenosing arteriopathy. [17][18][19] As there was no histological evidence of any such abnormality in our case, it was considered, on balance, to be a congenital malformation.…”

A 3-month-old infant developed signs of cardiac failure, which was initially attributed to cardiomyopathy. At 8 months, further investigations showed evidence of myocardial ischaemia with reversal of the flow of blood in the left coronary artery, which received no demonstrable inflow from the aorta. An anomalous connection of this artery with the pulmonary trunk was diagnosed but, at surgery, it was found that the arterial orifice was completely atretic, although the main stem was of normal size. A left internal thoracic arterial graft to the anterior descending coronary artery was performed, but he died on the third day after the operation. Postmortem examination showed a small dimple within the aorta at the site of the orificial atresia, extensive myocardial infarction, and two zones of myocardial bridging of the anterior descending coronary artery. We discuss the relationship of coronary orificial atresia with single coronary artery. Although they are related, they typically have different and contrasting clinical presentations. The possible role of the myocardial bridging is also considered.

A 13-year-old girl had recurrent syncope episodes and chest oppression during exercise caused by myocardial ischemia that was confirmed by stress myocardial scintigraphy. Echocardiography revealed mild aortic regurgitation (AR). Cineangiography revealed persistent opacification of the left coronary sinus. Freeing of the adherent left coronary cusp from the aortic wall increased antegrade left coronary flow and commissural resuspension restored AR. Postoperative recovery was uneventful and myocardial ischemia did not develop after surgery. Hence, although left coronary artery ostial isolation by aortic valve leaflet is rare, it can be successfully treated by aortic valve repair.
