Bilateral Pneumothorax Complicating Pacemaker Implantation, due to Puncture of the Left Subclavian Vein and Electrode Perforation of the Right Atrium

Pneumothorax occurs mostly due to needle injury of the pleura when trying to get access to the subclavian vein and rarely due to electrode perforation. The present case report is the first case presented about acute simultaneous iatrogenic bilateral pneumothorax due to puncture of the left subclavian vein and electrode perforation of the atrial wall, the pericardium, and the pleura. Risk factors, and how to avoid these complications, are highlighted, and symptoms, diagnostics, and management of pneumothorax and cardiac perforation are described.
