Repeat aortic valve replacement (AVR) for pseudoaneurysm of mitral-aortic intervalvular fibrosa (P-MAIVF) repair due to hemolytic anemia 6 years after AVR: a case report

Abstract

BackgroundPseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) after infective endocarditis and/or valve replacement is rarely reported, and transesophageal echocardiography and cardiac multidetector computed tomography are useful for diagnosis. Surgery is mostly recommended to prevent fatal complications.Case presentationA 61-year-old man underwent repeat aortic valve replacement (AVR) with repair of a P-MAIVF due to hemolytic anemia 6 years after AVR, and 4 months after treatment of sepsis and an infected abdominal aortic aneurysm. Two years after the surgery, the patient is alive and well with no recurrence.ConclusionsThe present case was considered to be a very rare case in which surgery was performed because the blood flow entering and leaving the P-MAIVF contacted the prosthetic valve ring, resulting in hemolysis, severe anemia, and heart failure.
