- 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. (Korean J Med 78:104-108, 2010)
