Delayed perforation of an atrial pacemaker electrode: Lifelong risk for a rare but serious complication

Nonspecific symptoms such as pleuritic or pericardial chest pain in cardiovascular implantable electronic devices patients, even with unremarkable ECG or device parameters, should always raise suspicion of electrode perforation, regardless of how long ago the implantation was performed.

We report the successful percutaneous management of a 77-year-old woman who had a dual-chamber pacemaker implanted more than 1 year ago and presented with pericarditis pain and compensated pericardial hemorrhagic tamponade. The symptoms were due to very late acute perforation of the atrial lead. This report is intended to raise awareness of procedure-related complications in the large group of cardiovascular implantable electronic device patients. Pleuritic or pericardial pain in these patients should raise suspicion of electrode perforation, as the risk of perforation is not restricted to the period immediately after implantation and a lifelong risk cannot apparently be excluded.
