Figure 4 Final perioperative X-ray image with confirmed lead positions. The final fluoroscopic image after implantation of the implantable cardioverter defibrillator system with left bundle branch area pacemaker stimulation demonstrates stable positioning of the left bundle branch area pacemaker lead within the interventricular septum, consistent with effective conduction system capture. The implantable defibrillator lead remains optimally placed in the apical septum, and the right atrial lead shows appropriate fixation. This final radiograph confirms correct depth and orientation of the left bundle branch area pacemaker lead, ensuring reliable physiological pacing and anticipated resynchronization.
