초록
심방 점액종은 심방 중격에서 발생하여 좌심방 혹은 우심방으로 천천히 점진적으로 커지며, 대부분은 좌회선 관상동맥에서 혈관 공급이 이루어지나 우관상동맥에서의 혈관공급은 드문 일차성 양성 종양이다. 본 증례에서 저자들은 경·중등도의 호흡곤란을 주소로 내원한 여자 환자에서 관상동맥조영술을 통해 진단된 우관상동맥에서 기시한 거대 심장 종양의 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
Abstract
A 55-year-old woman was referred to our hospital with a 6-month history of dyspnea (NYHA II-III). The physical examination revealed a grade 2/6 “tumor plop,” i.e., a low-pitched sound heard during early or mid-diastole. The chest X-ray showed mild cardiomegaly with lung congestion in both lower lung fields. Two-dimensional echocardiogram showed a large myocardial mass, prolapsing into the left ventricle during diastole. Chest computed tomography showed a multi-lobulated mass (6.8×4.1 cm) attached to the interatrial septum during systole and prolapsing into the left ventricle during diastole. Coronary angiography demonstrated large tumor vessels arising from and surrounding the posterior lateral branch of the right coronary artery. The mass was excised and the patient recovered uneventfully.
