Surgical treatment for right ventricular perforation caused by transvenous pacing electrodes: A report of three cases

Abstract

We experienced three cases of right ventricular perforation that were induced by transvenous pacing electrodes. The patients were a 72-year-old man who underwent percutaneous transluminal coronary recanalization and angioplasty, an 80-year-old woman who had temporary transvenous pacing for a complete atrioventricular block induced by acute valvular heart failure, and a 44-year-old man who had received a permanent pacemaker. All three patients were treated surgically. The first and second patients demonstrated either cardiac tamponade or hemopericardium necessitating pericardial drainage. Spontaneous hemostasis did not occur in cases 1 and 2, due to either anticoagulant therapy or myocardial degeneration. Such patients require surgical closure of the perforation and pericardial drainage as soon as pericardial effusion is confirmed. In contrast, middle-aged individuals without myocardial damage, such as patient 3, need only a simple removal and repositioning of the electrode followed by serial echocardiography.
