Imaging findings
Post-pacemaker placement chest radiograph, initially read as normal and without pneumothorax. Comparison with intra-procedural images reveals a change in the orientation and location of the atrial appendage lead. The lead is detached from the atrial wall and is seen hanging straight down within the atrium.
Key takeaways
This case demonstrates acute dislodgment of an atrial appendage pacemaker lead, a serious complication requiring reattachment. Careful comparison with previous or intra-procedural images is crucial for detecting such subtle but significant changes in device position.
