Left atrial aneurysm

Abstract

Aneurysms of the left atrium are rare abnormalities. They can be congenital or acquired. Whereas a true congenital aneurysm presents as isolated pathology, inflammatory or degenerative processes involving the endocardium are associated with the acquired type. The clinical records of 2 patients with the diagnosis of left atrial aneurysm were reviewed, along with the surgical strategies, current literature, and patient outcomes. Because of the risk of life-threatening complications, surgery is recommended even in asymptomatic cases. Resection and mitral valvuloplasty should be the treatment of choice.
