A 56-year-old woman suffering from mitral stenosis had underwent PTMC (percutaneous transvenous mitral commissurotomy) at age 46. After she developed congestive heart failure, mitral valve replacement (MVR) with Carbomedics 29M and tricuspid annuloplasty (TAP) was carried out. Four hours after admission to the ICU, massive bleeding was noticed. Cardiopulmonary bypass was restarted in the operating room. Laceration and hematoma were found at the posterolateral wall of the left ventricle. Under cardiac arrest with removal of the prosthetic valve, an internal tear was detected about 2cm below the anterolateral commissure (Miller Type III). The tear was covered with a horse pericardial patch (2×3cm) using 6-0 running sutures with reinforcement with gelatin-resorcine-formaline (GRF) glue between the laceration and the patch. MVR sutures in the annulus above the ventricular tear were first passed through the annulus, the pericardial patch and then the prosthetic cuff. Additionally, an epicardial tear was covered and reinforced with the fibrin sheet, GRF glue and pericardial patch in turn. Cardiopulmonary bypass was weaned easily without bleeding. The patient was intentionally on respiratory support with sedation for 3 days. The subsequent postoperative course was uneventful.
