Successful Retrieval of a Drifting Dislodged Leadless Pacemaker From the Left Common Iliac Artery.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Leadless pacemakers (LPs) have become increasingly popular alternatives to conventional transvenous systems because they eliminate leads and generator pockets, reducing the risks of infection, lead fracture, and venous thrombosis. Large multicenter studies have shown lower overall complication rates and fewer reinterventions compared to traditional pacemakers. Despite these advantages, LPs are not free from risk. Migration or embolization of the device is an exceptionally rare but potentially life-threatening complication that requires prompt recognition and intervention. Most reported migrations involve the pulmonary vasculature; arterial migration is exceedingly uncommon. We report the case of a 79-year-old woman with a history of atrial fibrillation and sinus pauses who was found to have imaging evidence of a foreign body in the left common iliac artery. Seven weeks earlier, she had undergone LP implantation. She was asymptomatic and hemodynamically stable on presentation. Computed tomography of the abdomen and pelvis revealed a 3-cm metallic density in the distal left common iliac artery. The patient underwent open retroperitoneal exploration with retrieval of the migrated pacemaker and removal of an associated thrombus, followed by primary arterial repair. Her postoperative course was uneventful, and she was discharged home on postoperative day 4 with intact distal perfusion. Migration of an LP into the arterial circulation is exceptionally rare, with only isolated cases reported in the literature. Early identification and timely surgical intervention are essential to prevent ischemic complications. This case underscores the importance of maintaining vigilance after device implantation and demonstrates that open surgical retrieval with primary arterial repair can be performed safely and effectively. Multidisciplinary collaboration between cardiology, vascular surgery, and radiology is crucial in managing these rare complications.
