Pseudo-aneurysm of the fibrous continuity zone between the aortic and mitral valves, the so-called "mitral-aortic intervalvular fibrosa" is a rare complication of acute infective endocarditis, rarely after an aortic valve replacement. We report the case of a large pseudo-aneurysm occurred in a 70-year-old man, who had a history of surgical aortic valve replacement 3 years before. There were no biological or clinical evidence for infective acute endocarditis. The originality of this observation can be summarized in three points: the late onset after surgery, the absence of any infectious context and the chronic nature of pseudo-aneurysm, without any complication during a follow-up of 12 months. Transesophageal echocardiography remains the best diagnostic tool.
