Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) can be a rare but life-threatening complication of infective endocarditis, cardiac surgery, or blunt chest trauma. Congenital heart diseases especially in young patients are reported as additionally predisposing factors. We present the case of an asymptomatic 52 years-old male with bicuspid aortic valve and gastrointestinal polyposis syndrome in whom a P-MAIVF was incidentally detected. The patient successfully underwent pseudoaneurysm surgical repair and aortic valve replacement and despite no evident causes were found we hypothesized addiotional underlying mechanism of P-MAIVF.
Keywords: bicuspid aortic valve; false aneurysm; mitral-aortic intervalvular fibrosa; perivalvular cavities; pseudoaneurysm.
