Key result
Percutaneous LV pseudoaneurysm closure successfully avoids redo surgery after patch dehiscence in a single patient.
Why the study?
Left ventricular pseudoaneurysm can occur as a late complication of surgical patch dehiscence following repair of post-infarct left ventricular free wall rupture.
Case Report (n=1)
Percutaneous closure of a left ventricular pseudoaneurysm after surgical patch dehiscence is feasible and may serve as an effective alternative to redo surgery.
BACKGROUND: Left ventricular free wall rupture is a life-threatening mechanical complication of ST-segment elevation myocardial infarction. In patients with a timely diagnosis, emergent surgical patch repair is the cornerstone of management; re-rupture, surgical patch dehiscence, and left ventricular pseudoaneurysm (LVPA) are potential late complications after surgery. CASE SUMMARY: A 72-year-old man presented with NYHA functional class III dyspnea 4 months after surgical patch repair. We report, to our knowledge, the first case of successful percutaneous closure of LVPA resulting from surgical patch dehiscence. DISCUSSION: LVPA after surgical repair is a serious late complication. Multimodality imaging and careful case planning allowed for successful device closure with excellent clinical outcome. TAKE-HOME MESSAGES: Multimodality cardiac imaging is essential for accurate diagnosis and management of acute left ventricular free wall rupture and LVPA resulting from surgical patch dehiscence. Percutaneous closure of LVPA after surgical patch dehiscence is an effective and safe alternative to redo surgery.

Traynor et al. (2025) conducted a case report in Left ventricular pseudoaneurysm after surgical patch dehiscence (n=1). Percutaneous closure of left ventricular pseudoaneurysm was evaluated on Successful device closure and clinical outcome. Percutaneous closure of a left ventricular pseudoaneurysm resulting from surgical patch dehiscence was successfully performed in a 72-year-old man, providing an effective alternative to redo surgery.
