Key result
Closure of a late-phase left ventricular pseudoaneurysm with mitral valve replacement was successfully performed in a 40-year-old man with a history of three prior mitral valve surgeries.
Why the study?
Rupture of the left ventricular posterior wall rarely occurs in the late phase after mitral valve replacement, presenting as left ventricular pseudoaneurysms, which remain challenging to repair.
Case Report (n=1)
Late-phase left ventricular pseudoaneurysm after multiple mitral valve surgeries can be successfully treated with surgical closure and mitral valve replacement.
May guide rare reoperative LV pseudoaneurysm cases; hypothesis-generating and should not yet change practice.
Rupture of the left ventricular posterior wall is a fatal complication during mitral valve replacement (MVR), and rupture mainly occurs intraoperatively and up to several days after MVR, but it rarely occurs in the late phase, such as several years postoperatively. Late rupture occasionally presents as left ventricular pseudoaneurysms (LVPAs). A 40-year-old man who had a three-time history of mitral valve surgery for infectious endocarditis was incidentally found to have a left ventricular aneurysm with no symptoms. He underwent closure of a LVPA with MVR. Although there are various surgical techniques to close LVPAs after mitral valve repair, it is still a challenging problem. Here, we report the case of a patient who successfully underwent LVPA repair with MVR and describe the technique.

Ishida et al. (2021) conducted a case report in Left ventricular pseudoaneurysm (n=1). Closure of left ventricular pseudoaneurysm with mitral valve replacement was evaluated on Surgical success. Closure of a late-phase left ventricular pseudoaneurysm with mitral valve replacement was successfully performed in a 40-year-old man with a history of three prior mitral valve surgeries.
