May support IABP-assisted off-pump LV rupture repair post-MVR; hypothesis-generating case report requiring prospective validation.
INTRODUCTION: Left ventricular (LV) rupture is a not as frequent, but potentially lethal complication of mitral valve replacement or repair. PRESENTATION OF CASE: We report a case of a 67-year-old man who underwent mitral valve replacement and Cox Maze IV procedure. A massive bleed from the LV rupture was noted postoperatively while the patient was extubated. The control of bleeding was impossible until an IntraAortic Balloon Pump (IABP) was inserted. A bovine pericardial patch was applied, overlapping an extensive epicardial area, perimetrically of the hematoma. Between the epicardium and the pericardial patch we applied an autologous fibrin sealant. DISCUSSION: The off-pump technique used to repair the LV rupture after a MVR, is more feasible when the patient is supported by an IABP that subsequently decreases the tension of the myocardial suture site. CONCLUSION: The IABP, is a necessary device, that decreases the tension along the suture site post a left ventricular rupture following a MVR.
