title: Surgical treatment for abnormal echoes in the left ventricular outflow tract caused by ruptured mitral chordae tendineae.
abstract: We performed surgical treatment for abnormal echoes in the left ventricular outflow tract caused by ruptured mitral chordae tendineae. An asymptomatic 68-year-old man had a chordal rupture exhibiting a tumor-like lesion in the left ventricular outflow tract on echocardiography. Considering a high level of mobility of the tumor as well as its texture, the risk of embolization was found to be significant. Therefore, it was decided on the surgical resection of the tumor-like lesion under extracorporeal circulation. We report a highly rare case of rupture in redundant mitral chordae tendineae without mitral regurgitation, revealed by uncommon echoes in the left ventricular outflow tract during systole.
