title: The mystery of the lost and found right coronary artery.
abstract: Most coronary artery anomalies are discovered only incidentally during coronary angiography. Recognition and identification of these anomalies especially during coronary intervention procedures are of importance because of their occasional association with symptoms due to atherosclerotic coronary disease. Anomalous origin of the right coronary artery (RCA) from the left anterior descending coronary artery (LAD) is one of the most uncommon coronary anomalies. We report an extremely interesting case of anomalous RCA from the LAD presenting as acute inferior ST elevation MI, with ostial total block of the RCA, precluding its visualization during coronary angiography. Interventional Cardiologists need to be aware of such anatomical variations, as occasionally, this can lead to a diagnostic dilemma, as in our case.
