title: Pseudoaneurysm of the mitral-aortic intervalvular fibrosa on a native aortic valve following infective endocarditis.
abstract: Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (MAIVF) rarely forms on native aortic valve after infective endocarditis (IE). It is often fatal because of its rapid progress, high rates of rupture and recurrence, and worsening effects on the systemic condition. Echocardiography, especially transesophageal echocardiography, plays an important role in the diagnosis and assessment of this condition. We experienced a rare case of a patient with an unfortunate course following native aortic valve IE. After the patient had undergone surgical evacuation of a blood clot due to the rupturing of an embolomycotic cerebral aneurysm, a pseudoaneurysm of the MAIVF was found. Aortic valve replacement and pseudoaneurysm repair were performed 3 months after the neurosurgery. Echocardiographic still images were obtained during these two operations.
