CTICasesRight Atrial Pacemaker Lead Perforation
Imaging findings
Chest radiographs and subsequent chest CT scans show the right atrial pacemaker lead extending significantly outside the expected confines of the right atrium, perforating the atrial wall and entering the adjacent middle lobe parenchyma of the right lung.
Key takeaways
Chronic cardiac implantable electronic device lead perforation through the thin-walled right atrium is a rare but well-documented complication. Despite the extracardiac and intrapulmonary location of the lead, transvenous lead extraction can sometimes be performed successfully with gentle traction under appropriate surgical backup.
