A colossal atrial myxoma

Abstract

Atrial myxomas are the most common benign primary tumor of the heart. These cardiac growths can masquerade as mitral stenosis and infective endocarditis. A 35-year-old man presented with complaints of nonspecifi c symptoms. Echocardiogram revealed a large atrial myxoma occupying the left atrium. Excision revealed a 14 × 8 × 6 cm3 tumor attached to a 4 × 3 × 2 cm3 stalk of septal tissue. We describe a giant left atrial myxoma. We were not able to fi nd another myxoma as big as this one in the literature, so we are reporting it.
