Interventricular Septal Hematoma Complicating Left Bundle Branch Area Pacing: A Case Report-The Devil Is Not So Black as He Is Painted.

ABSTRACT

BACKGROUND: This case report outlines the presentation of an emerging complication arising from left bundle branch area pacing (LBBAP). CASE SUMMARY: A 43-year-old male with no history of cardiac problems experienced recurrent episodes of syncope with no prodromal symptoms. During monitoring in the emergency department, the patient underwent an episode of asystole, leading to LBBAP implantation. The procedure encountered technical challenges, resulting in an interventricular septal hematoma and subsequent ventricular arrhythmias. Despite initial concerns, conservative management led to resolution, demonstrated through echocardiographic follow-ups. DISCUSSION: This report underscores the significance of ventricular arrhythmias as indicators of interventricular septal hematoma, providing insights into its diagnosis, management, and implications for LBBAP procedures.
