Submitral Aneurysm Secondary to Infective Endocarditis: Review of Literature and Case Report

Chaudappa Shakapur, Mahesh Honnalli and Sagar Mali*

Submitral aneurysm is seldom reported worldwide. It is thought to be caused by weakness in the cardiac musculature due to abnormal embryogenesis. Mostly these aneurysms were reported from Africa in black African population. Apart from congenital cause, many other causes have been put forth as its etiology. Among these endocarditis is a known infective etiology. Submitral aneurysm secondary to left sided infective endocarditis is rare. The definitive diagnostic modality and treatment of submitral aneurysm remains echocardiography and surgical correction of aneurysm respectively. The submitral aneurysms as well as infective endocarditis both are known independent risk factors for thromboembolic events and subsequent stroke increasing both morbidity and mortality. The management of submitral aneurysm includes surgical correction by repair of the aneurysm but it requires careful consideration of surgical resection of diseased paravalvular tissue or diseased mitral valve and correction of mitral regurgitation by preforming mitral valve replacement. The surgical approach reduces the risk of recurrent endocarditis and thromboembolic events, thus reducing the risk of stroke. Prior to surgery, patient should receive prophylactic antibiotics for one to two weeks to control any active infective endocarditis. For us successful treatment of a patient suffering from submitral aneurysm due to infective endocarditis was challenging. We are reporting a case of submitral aneurysm secondary to infective endocarditis along with review of literature on infective endocarditis and submitral aneurysma.
