Submitral Aneurysm of the Left Ventricle

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.

Ruptured submitral aneurysm

Submitral aneurysm is a rare entity, with around few hundred cases reported till date. Presentation can be varied. We describe here a case of submitral aneurysm in a young male with rupture into the left atrium cavity.

Submitral aneurysm of the left ventricle

Submitral aneurysm is a rare cardiac pathology of uncertain origin with varied clinical manifestations. Recent studies have revealed a congenital basis of this pathology, although genetic link has been suspected because of the racial predilection. The other suggested aetiologies are infection and inflammation. The case reported here is that of a young female with a large submitral aneurysm presenting in a state of cardiogenic shock. In addition, the presence of raised inflammatory parameters indicates that the cause of origin of this aneurysm is related to inflammation.
