Giant Lambl's excrescences of papillary muscle and aortic valve: echocardiographic, angiographic, and pathologic findings.

A 54-year-old female with rheumatic heart disease was found to have a mass in the left ventricle by echocardiography and angiography. Subsequently, giant Lambl's excrescences of papillary muscle and aortic valve were confirmed by operation and pathologic examination. Possible complication from cardiac catheterization could be avoided by the utilization of echocardiography prior to catheterization.
