Abstract:
A 60 year-old female underwent mitral valve replacement with a Duromedics valve. She was in good condition during weaning from cardiopulumonary bypass. However, rupture of the left ventricle was manifested by massive bleeding just after dis-contination of cardiopulmonary bypass. A large hematoma accompanied by bleeding was observed in the posterior atrio-ventricular groove. The patient was quickly put back on total cardiopulmonary bypass. A slight laceration was suspected in the membranous portion of the ventricular septum just below the mitral annulus. Re-valve replacement was performed by reinforcing the mitral annulus with a Dacron patch. This patient was removed from cardiopulmonary bypass, but died of multiple organ failure in 7 days after operation. At autopsy, the left ventricular rapture was identified just below annuls in the area of the atrioventricular groove. Furthermore, extensive hematoma was noted in the posterior atrioventricular groove.
