A mitral-aortic intervalvular fibrosa false aneurysm in a patient without overt heart disease.

False aneurysms originating from mitral-aortic intervalvular fibrosa are clinically very rare. A 22-year-old male patient without overt heart disease was admitted to the cardiology department of the Gulhane Military Academy of Medicine, Ankara, Turkey, with a false aneurysm located between the left ventricular outflow tract and the anterior left atrium. The false aneurysm was repaired at the Department of Cardiovascular Surgery, and the patient was discharged 10 days after the surgery.
