Septal Artery Injury During Left Bundle Branch Area Pacing: Electrophysiological Warning and Coil Embolization.

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
backgroundLeft bundle branch area pacing (LBBAP) requires deep septal lead implantation and carries a risk of septal vascular injury. CASE SUMMARY: A 58-year-old man with binodal disease underwent dual-chamber pacemaker implantation using LBBAP. Initial high septal lead placement was associated with markedly elevated impedance and suboptimal pacing parameters. After repositioning, parameters normalized. However, the patient developed acute chest pain, ST-segment elevation, and ventricular tachycardia. Coronary angiography demonstrated septal branch perforation with contrast extravasation, and echocardiography confirmed an interventricular septal hematoma. Transcatheter coil embolization achieved complete hemostasis with favorable recovery. DISCUSSION: Abnormal pacing parameters and ventricular arrhythmias may represent early electrophysiological markers of septal vascular injury during LBBAP, providing important insights into its recognition, management, and procedural implications. TAKE-HOME MESSAGES: Septal branch injury is a rare but potentially serious complication of LBBAP. Early recognition and prompt imaging-guided intervention are essential to ensure procedural safety.
