Multimodality Imaging of Submitral Left Ventricular Aneurysm

Submitral left ventricular aneurysms are a rare nonischemic aneurysm thought to be developmental in origin. These aneurysms invariably occur at the site of posterior mitral annulus and lead to mitral valve incompetence. We hereby describe a case of a 30-year-old adult with a rare form of submitral left ventricular aneurysm involving whole of the posterior mitral annulus. Multimodality imaging with two-dimensional echocardiography, three-dimensional echocardiography, computed tomography and invasive left ventriculography helped the patient to undergo successful resection of the aneurysm along with mitral valve replacement.
