Left Ventricular Perforation during Catheter Ablation in a Patient with Idiopathic Thrombocytopenic Purpura

Preoperative gamma-globulin therapy was recently performed to prevent bleeding complications in a patient with concomitant idiopathic thrombocytopenic purpura undergoing cardiac surgery. Here we report the case of a 75-year-old male patient with idiopathic thrombocytopenic purpura, chronic aortic dissection, and funnel chest in whom a left ventricular perforation sustained during catheter ablation was repaired during emergent surgery. Despite preoperative gamma-globulin therapy not being performed, bleeding complications were prevented because platelets were preserved by avoidance of cardiopulmonary bypass use. Although the funnel chest made it difficult to secure the operative field, the deep pericardial sutures were effective in repairing the perforation without cardiopulmonary bypass.
