Left atrial myxoma, ruptured chordae tendinae causing mitral regurgitation and coronary artery disease.

ABSTRACT

Mitral regurgitation is uncommon with left atrial myxoma. The echocardiographic assessment of presence of mitral regurgitation and its severity are impaired by the presence of left atrial myxoma. We describe an uncommon association of left atrial myxoma with coronary artery disease and mitral regurgitation. MR was reported as mild on pre‑operative transthoracic echocardiography but found to be severe due to ruptured chordae tendinae during intra‑operative transesophageal echocardiography, which lead to change in the surgical plan to mitral valve replacement in addition to excision of myxoma.
