Pseudoaneurysm of the mitral-aortic intervalvular fibrosa as a complication after minimally invasive mitral valve repair.

Pseudoaneurysm of the mitral-aortic intervalvular body is a rare condition, which has been reported as a result of endocarditis, chest trauma or cardiac surgery. We describe here the first case after minimally invasive mitral valve repair. Such a complication may be overlooked in the early postoperative echocardiographic study and may lead to fistula formation, compression of adjacent structures, infection, or rupture. Both computed tomography and echocardiography provide a detailed anatomy of the pseudoaneurysm and its communication with the left ventricular outflow tract.
