A mitral-aortic intervalvular fibrosa pseudoaneurysm is a rare complication after aortic and mitral valve replacement and aortic root replacement. A left ventricular pseudoaneurysm after mitral valve replacement is also a rare complication. Here, we describe a 48-year-old woman with a history of a Bentall operation and mitral valve replacement 6 years before, presenting with double pseudoaneurysms in the left ventricle and mitral-aortic intervalvular fibrosa, detected via transesophageal echocardiography.
