Pseudoaneurysm of the Mitral-Aortic Intervalvular Fibrosa with Fistulous
Flow into the Left Atrium Masquerading as Severe Mitral Regurgitation
AbstractPseudoaneurysms of the mitral-aortic intervalvular fibrosa are a
well-described complication of aortic valve prosthetic endocarditis.
Pseudoaneurysms in this location may be complicated by formation of
fistulous tracts with adjacent structures. Herein we describe a case in
which fistulous flow into the left atrium produced an eccentric jet on
color flow Doppler imaging which masqueraded as severe mitral
