Key result
Skirted conduit technique successfully repairs ruptured LV pseudoaneurysm and acquired Gerbode defect while preserving bioprosthesis.
Why the study?
Left ventricular pseudoaneurysm with acquired Gerbode-type defect after mitral bioprosthetic valve replacement is an uncommon but life-threatening complication requiring detailed diagnostic and surgical management.
Case Report (n=1)
This case highlights the critical role of multimodality imaging in diagnosing an acquired Gerbode-type defect after mitral valve replacement and demonstrates successful repair using a skirted conduit technique.
Raises awareness of rare post-MVR LV pseudoaneurysm with Gerbode shunt; leaves open incidence, prevention, and optimal repair strategies.
We present a 61-year-old woman with progressive dyspnea 20 days after mitral bioprosthetic valve replacement. Multimodality imaging revealed a left ventricular pseudoaneurysm rupturing into the right atrium-an acquired Gerbode-type defect with significant left-to-right shunt-most likely caused by perioperative atrioventricular annular injury. Emergency surgery using a skirted conduit technique successfully repaired the rupture while preserving the functioning bioprosthesis. This case highlights the critical role of multimodality imaging in diagnosing and surgically managing this uncommon but life-threatening complication.

Wei et al. (2026) conducted a case report in Left ventricular pseudoaneurysm with acquired Gerbode-type defect (n=1). Emergency surgery using a skirted conduit technique was evaluated. Emergency surgery using a skirted conduit technique successfully repaired a ruptured left ventricular pseudoaneurysm with an acquired Gerbode-type defect while preserving the bioprosthesis.
