Pseudoaneurysm of the Mitral-Aortic Intervalvular Fibrosa (MAIVF): A Comprehensive Review

Pseudoaneurysm of Mitral-Aortic Intervalvular Fibrosa Following Regurgitation of Congenital Bicuspid Aortic Valve in a 63-year-Old Patient: A Case Report

“…Since the MAIVF is relatively avascular, it becomes more prone to infection, trauma or pseudoaneurysm formation [5,6] . P-MAIVF is a rare but potentially life-threatening entity [1,7,8] . It commonly occurs in patients with infective endocarditis, aortic valve surgery, or chest trauma [1,5,6] .…”

Transapical Closure of a Pseudoaneurysm of the Mitral-Aortic Intervalvular Fibrosa

“…The left circumflex coronary artery is most often involved, but the other arteries can be in volved to varying degrees. 1 The pseudoaneurysm can rupture into the aorta, the left atrium, 2 or the peri cardium (this last resulting in cardiac tamponade). 3,4 These lifethreatening sequelae suggest that early treat ment is advisable.…”

“…This condition most likely arises from fibrotic damage caused by infection or by sutures rooted in the MAIVF during valve replacement. 1 Although rare, PMAIVF can produce lifethreatening sequelae. Certainly it warrants early definitive treatment.…”

Pseudoaneurysms of the Heart

“…The most common cardiac pseudoaneurysm is of the left ventricular myocardium after a myocardial infarction. Other cardiac sites include the mitral-aortic intervalvular fibrosa, 6 the right ventricular outflow tract 7 , native and grafted coronary arteries, 4 and the atria. 8 Although myocardial infarction is the most common cause of left ventricular pseudoaneurysms, 3 prior aortic valvular surgery and endocarditis most often precede pseudoaneurysms at the mitral-aortic intervalvular fibrosa.…”
