Aneurysm of the mitral-aortic intervalvular fibrosa as a rare cause of angina pectoris: Angiographic demonstration

Aneurysms of the mitral‐aortic interventricular fibrosa (MAIF) are exceptionally rare complications, commonly following aortic valve endocarditis. This report describes the angiographic findings of such an aneurysm, in a patient who developed an uncommon symptomatology of unstable angina pectoris, caused by the aneurysm's expansion against the coronary arteries. Surgical treatment is also discussed. Cathet. Cardiovasc. Diagn. 42:423–426, 1997. © 1997 Wiley‐Liss, Inc.
