Late Manifestation of Coronary Sinus and Left Atrial Perforation of a Left Ventricular Pacemaker Lead at Extraction

摘要

A 56-year-old man presented for lead extraction of a left ventricular (LV) lead that had been deactivated due to hiccups and of a right ventricular (RV) lead with a high threshold. Pus was noted upon entering the pocket. The right atrial and RV leads were extracted, but traction on the LV lead caused ischemia and was not performed. An echocardiogram demonstrated the lead in the left atrium and a robotic-assisted thoracotomy was used to remove the lead that had unroofed the coronary sinus, gone into the left atrium, and perforated through the free wall into the pericardium.
