Subacute Right Ventricular Perforation by Pacemaker Lead Causing Left-Sided Hemothorax and Epicardial Hematoma

Abstract EN

We report a case of right ventricular wall perforation by a pacemaker lead in a 78-year-old female 18 days after a permanent pacemaker insertion.

This injury necessitated explant of the perforating lead and implantation of a new one with surgical backup.

We review the literature and discuss the possible risk and protective factors including lead models that were associated with higher incidence of perforation.

We review the traditional pacing parameters and their lack of reliability to diagnose perforation and the need for low threshold to utilize imaging in appropriate clinical scenarios.

The authors believe this case is of educational value to all health care professionals, especially emergency medicine and internal medicine residents, who routinely see patients with pacemakers complaining of chest pain, shortness of breath, or dizziness.
