Pseudoaneurysm in the mitral-aortic intervalvular fibrosa. A cause of mitral regurgitation

Left ventricular outflow tract pseudoaneurysm is an uncommon but potentiall y catastrophic complication of aortic Valve surgery, aortic valve endocardi tis or chest trauma. We describe a case of a left ventricular outflow tract pseudoaneurysm I month after an aortic valve replacement that caused a sys tolic compression of mitral valve and a severe regurgitation. The diagnosis was confirmed using transoesophageal echocardiography, magnetic resonance image and intraoperative endoscopy. Surgical repair of the pseudoaneurysm c orrected the mitral regurgitation.
