Postpericardiotomy syndrome and cardiac tamponade following transvenous pacemaker placement

Abstract

This is the first reported case of cardiac tamponade presumed to be caused by postpericardiotomy syndrome (PPS) following endocardial pacemaker placement. An 84-year-old woman developed fever and dyspnea 3 weeks after pacemaker placement. Physical examination revealed hypotension, tachycardia, and pulsus paradoxus. Auscultation revealed clear lungs and diminished heart sounds. The sedimentation rate was 60 mm/h. Echocardiography revealed a large pericardial effusion with signs of cardiac tamponade. Surgical drainage of the pericardial space resulted in complete resolution of symptoms. The pericardial fluid was culture- and cytologically negative. PPS is a common complication of cardiothoracic surgery and chest trauma. It rarely occurs after percutaneous procedures such as percutaneous transluminal coronary angioplasty and transvenous pacemaker placement. While usually having a benign, self-limited course, PPS can cause a serious complication as illustrated in this case report.
