Three cases of right coronary anomaly confirmed by multi-detector computed tomography / 대한내과학회지

ABSTRACT

Congenital anomaly of the right coronary artery is a very rare disease. It can cause syncope, angina pectoris, acute myocardial infarction, ventricular fibrillation and sudden cardiac death during exercise in the young population. The dominancy of the coronary artery, and the site, shape and pathway of the right coronary artery seems to play a key role in developing those above mentioned events. Especially, it has been known that the right coronary artery that courses between the aorta and pulmonary trunk increases the risk of sudden death. Therefore, precise evaluation is needed to diagnose the presence and type of coronary artery anomaly. Nowadays, multi-detector computed tomography is used to diagnose coronary anomalies and this provides clear images of coronary anomaly in a safe and noninvasive way. We report here on three cases of right coronary anomaly that coursed between the aorta and pulmonic trunk, and this was confirmed by multi-detector computed tomography.
