Cardiac pseudoaneurysm as a complication of native mitral valve infective endocarditis

Abstract

Background The delayed development of a mitral valve annulus pseudoaneurysm is a rare and late complication of a native mitral abscess cavity. Case summary Currently, there are no documented cases of a pseudoaneurysm developing from an abscess cavity of the posterior annulus of the native mitral valve. We report a case of a patient who presented with worsening progressive shortness of breath that was found to be secondary to a pseudoaneurysm. This was detected by 2D echocardiogram and cardiac computed tomography angiography. Discussion In our case, the patient developed a late complication of a ventricular pseudoaneurysm originating from the mitral annular area of the abscess cavity. Per the surgical literature, one method to avoid the aforementioned complication is via cavity repair with a bovine patch.

Pseudoaneurysm of the left ventricular free wall occurring after cardiac surgery of endocarditis affecting mitral and aortic valves: a case report

“…However, a conservative approach may be recommended for asymptomatic patients and those with a higher risk of postoperative morbidity and mortality [ 10 ]. Recently, percutaneous closure has been reported as an alternative for high-risk surgical candidates [ 11 , 16 ].…”

“…The second hypothesis suggests that bacterial invasion of the annular region weakens the ventricular wall, predisposing it to dissection and, consequently, the formation of a pseudoaneurysm, as observed in our patient. [ 4 ]…”
