Assessment of a Left Ventricular Mass Using Three-Dimensional
Transesophageal Echocardiography
Abstract
A 47-year-old man with an asymptomatic left intraventricular mass was
referred to our hospital. Transthoracic echocardiography (TTE) revealed
a mass attached to the lateral wall of the left ventricle, with no other
structural changes. The true view mode of three-dimensional TEE was more
visual, and revealed a regular, very mobile, ball-like mass that was
attached to the anterolateral papillary muscle. The mass was then
surgical excised. Histopathological analysis indicated that the mass was
a myxoma. Cardiac myxomas are commonly seen in the left atrium. Left
ventricular myxomas are extremely rare, especially one attached to the
papillary muscles.
