Percutaneous coronary intervention on a single coronary ostium

Anomalous origin of the left main coronary artery from the right sinus Valsalva is extremely rare when not associated with other congenital cardiac anomalies. It is reported to constitute just 0.019% of angiographic series. These patients are usually asymptomatic and prone to atherosclerotic disease, however, they also may have normal coronary arteries. We report here the unusual case of a patient with ST segment elevation myocardial infarction who was managed by percutaneous coronary intervention performed through single coronary ostium.
