Abstract
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.
