Abstract:
Cardiac perforation by a pacemaker lead that causes left hemothorax without pericardial effusion is rare and life threatening. So, we report a surgically salvaged case. A 55-year-old man underwent insertion of adevice for cardiac resynchronization therapy and defibrillation. On the second postoperative day, the patient fell into shock state after defecation. Electrocardiogram showed pacing failure and computed tomography (CT) showed left hemothorax without pericardial effusion. A drainage tube was placed in the left pleural cavity, and bleeding was massive and continuous. We then performed emergency surgery for suspected cardiac perforation by the pacemaker lead. The right ventricular lead had penetrated the ventricle, which was surgically repaired.
