Key result
Dual atrioventricular approach successfully repairs massive postoperative LV pseudoaneurysm.
Why the study?
Left ventricular pseudoaneurysm is an uncommon but potentially fatal complication following atrioventricular groove rupture after mitral valve surgery.
Case Report (n=1)
No
Dual approach may enable repair of contained atrioventricular groove rupture; leaves open generalizability beyond this single case.
Background Left ventricular pseudoaneurysm (LVPA) is an uncommon but potentially fatal complication following atrioventricular groove rupture. Case Description We present a patient with a massive LVPA involving the lateral commissure and under the mitral P3 segment following coronary artery bypass grafting and mitral valve (MV) repair. MV replacement and arteriovenous pseudoaneurysm were repaired by dual approach via the left atrium with excision of the previously dehisced mitral ring to expose the defect and patch repair the atrioventricular defect through the pseudoaneurysm free wall. Conclusion This is a rare case of a large subacute postoperative LVPA repaired by dual atrial–ventricular approach to treat a contained atrioventricular groove rupture.

Fishberger et al. (2023) conducted a case report in Left ventricular pseudoaneurysm (LVPA) (n=1). Dual atrial-ventricular approach for LVPA repair was evaluated on Successful closure of LVPA and patient survival. A massive subacute postoperative left ventricular pseudoaneurysm was successfully repaired using a dual atrial-ventricular approach to treat a contained atrioventricular groove rupture.
