CTICasesPerforation of Right Atrial Pacemaker Lead into Lung
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
Post-placement radiographs initially showed an apparently well-positioned right atrial pacemaker lead. Subsequent CT demonstrates the right atrial lead perforating the right atrium and extending into the anterior segment of the right upper lobe. No significant scarring around the lead tip was noted.
Key takeaways
Pacemaker lead perforation, while more commonly seen with right ventricular leads, can also occur with right atrial leads. This case highlights a right atrial lead perforating into the lung parenchyma, which can be initially subtle on plain radiographs and may not always be associated with immediate complications like hemothorax or significant tissue damage from electrical pulse, though pneumothorax is a known risk.
