초록
우 관상동맥의 선천성 기형은 매우 드문 질환으로, 젊은 사람에서 운동 중에 실신, 협심증, 급성 심근경색증, 심실 세동, 돌연사 등을 일으킬 수 있다. 우 관상동맥의 기형이 이러한 임상양상을 나타내는 데는 관상 동맥의 우세양상, 대동맥에서 기형 혈관 입구의 위치와 모양 및 그 주행 경로가 중요한 역할을 하는 것으로 알려져 있기에 관상동맥 기형의 유무와 종류를 진단하기 위한 적극적인 검사와 치료가 필요하다. 최근에는 이러한 관상동맥의 기형의 진단에 다중열검출기 전산화 단층촬영술이 이용되어 비침습적인 방법으로 정확하게 관상동맥 기형에 대한 선명한 영상을 얻을 수 있다.
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.(Korean J Med 72:231-236, 2007)
