A 37-year-old healthy woman presented to our emergency department because of episodes of palpitation and syncope. Her general physical examination was unremarkable. The x-ray of her chest was normal except for bulging near the left border of her heart (Figure 1). Her ECG exhibited sinus tachycardia and short runs of monomorphic ventricular tachycardia. Consequently, the patient was admitted to the cardiology intensive care unit for further investigation. Transthoracic echocardiogram and transesophageal echocardiogram showed a large, rounded, extracardiac hypoechogenic mass within the posterosuperior portion of the heart (Figure 2A). Further evaluation of the mass was performed by cardiac computed tomography angiography using 64-row multidetector computed tomography. Cardiac computed tomography angiography revealed a large, hypodense, epicardial solid mass (9x6x6 cm) with small central areas of enhancement. The mass was located posteriorly to the right ventricle outflow tract and ascending aorta, at the level of the left coronary sinus of Valsalva, causing compression and displacement of the left atrium and the left superior pulmonary vein. In addition, the left main coronary artery, the left anterior descending artery, the left circumflex artery, and the first diagonal artery were completely surrounded by the tumor and showed diffuse, slight narrowing (Figure 2B and 2C). On operating, the mass was unresectable because of its proximity to the coronary arteries. A histological examination revealed a cavernous-type hemangioma (Figure 2E). One week after the operation, cardiac magnetic resonance imaging was performed and showed a large, well-defined epicardial
