Stormy Course of a Huge Submitral Aneurysm Causing Low Cardiac Output State

Congenital Sub-Mitral Aneurysm: Anesthetics and Surgical Management

ABSTRACT

A sub-mitral left ventricular aneurysm is a rare condition. It is a congenital outpouching of the left ventricular wall, invariably occurring adjacent to the posterior mitral leaflet. Sub-mitral aneurysm (SMA) has usually been reported as a consequence of myocardial ischemia (MI), rheumatic heart disease, tuberculosis, and infective endocarditis. Nevertheless, there have been few case reports of congenital SMA in India. It usually presents with symptoms of heart failure. We report a rare case of congenital SMA in a 27-year-old young Indian and its successful management through a trans-aneurysmal approach.

Multimodality cardiac imaging of submitral left ventricular aneurysm with concurrent descending aorta mycotic aneurysm

We present a case of a 20-year-old Malay man with underlying tuberculous (TB) lymphadenitis who presented with shortness of breath and found to have submitral left ventricular aneurysm (SLVA). SLVA is well recognised but rare. Incidence of SLVA in Malay has never been documented. This is the first reported case of SLVA in Malays with concomitant thoracic aorta mycotic aneurysm. TB has been reported to be associated with SLVA. Treatment is either surgical or conservative. Imaging is required for diagnosis and preoperative assessment. Multimodality imaging include echocardiography (ECHO), cardiac CTangiography and the robust multiparametric cardiac MR (CMR). ECHO is the first line imaging and useful for initial detection of the aneurysm. CMR including the late gadolinium enhancement allows excellent visualisation of the LV aneurysm, tissue characterisation, cardiac function and detection of associated pathology as shown in this case.
