Mitral-aortic intervalvular fibrosa aneurysms and pseudoaneurysms are rare entities but can lead to different, unpredictable and sometime dramatic complications. We report the case of a young woman presenting a congenital form of this aneurysm. Given the clinical and symptomatological progression, surgical treatment is mandatory. After a transverse aortotomy, we resected the aneurysm. Performing a pulmonary arteriotomy allows adequate control of the left main coronary artery, adjacent to the lesion. We repaired the remaining cavity, not far from the left coronary aortic cusp, with a double patch of bovine pericardium.
