subvalvar mitral aneurysm, an update of what we know, at the disease's diamond jubilee.Abstract
The SMA is part of an entity related to an innate weakness of the ventricular wall, specifically in the area of implantation of the posterior mitral cusp, resulting in loss of valve architecture and, consequently, regurgitation and ventricular aneurysmal dilatation. To complete its diagnosis, the presence of the aneurysm is not enough, it is necessary to exclude that its aetiology is ischemic. The main hypothesis is that of congenital origin added, sometimes, to the presence of inflammatory processes that function as triggers, in predisposed patients. Imaging methods play a fundamental role in diagnosis and anatomical definition, to decide the best form of surgical approach. With improved techniques for aneurysm exclusion, plasty, and mitral valve replacement, patients have a favorable prognosis. Today it is a documented disease in America, Europe and Asia, predominantly in the young, African or Afro-descendant population, however with documented cases in young individuals of all races and it is due to this geographical expansion that it should be considered as a cause of mitral regurgitation in young patients.
