[Mitral subvalvular aneurysm of the left ventricle]

A 21-year-old white man presented with cardiogenic shock and refractory pulmonary congestion. At the transthoracic echocardiogram a subvalvar left ventricular aneurysm of the inferior wall with severe mitral regurgitation was observed. The outcome was favorable after surgical correction of the mitral regurgitation and of the subvalvar aneurysm. We emphasize that, whenever possible, valvar repair is better than mitral replacement, since annulus tissue fragility causes suturing of the mitral prosthesis to be difficult.
