ABSTRACT
The mitral subvalvular ventricular aneurysm is a rare cardiac condition with an origin not yet well defined. Since the first report by Corvisart in 1812, several reports have coincided with pointing out the significant incidence among Africans, which has been the scene of several discussions until today. There are several controversies around this issue; the current consensus is several interrelated factors such as the weakness of the posterior fibrous ring of the mitral valve is at the basis of its occurrence, which can be based on a sustained basis, congenital aneurysm, infectious, inflammatory or degenerative processes involving the endocardium. The diagnosis of certainty is made by echocardiogram, and the treatment is eminently surgical. 28-year-old Angolan patient with a mitral subvalvular aneurysm is described as the cause of severe mitral regurgitation and heart failure, which was successfully corrected surgically.
