Delayed post-operative perforation of the interventricular septum is a rare complication of left bundle branch area pacing, with an estimated incidence of 0.08-0.33%.
Delayed post-operative perforation of the interventricular septum is a rare complication of LBBAP (incidence 0.08-0.33%) that can cause pacing issues or ventricular tachycardia.
Delayed post-operative perforation of the interventricular septum is a rare complication of left bundle branch area pacing (LBBAP), with an incidence of 0.08-0.33%.1-4 It usually occurs within days or weeks of implantation, and can result in a rise in capture threshold and/or ventricular undersensing. Overt perforation into the left ventricular cavity may theoretically also result in thrombo-embolic events, although this complication has yet not been reported. In this issue, Hsieh et al.5 present a case of delayed (post-operative) LBBAP septal perforation on the night following implantation, which resulted in sustained ventricular tachycardia (most probably induced mechanically).

Haran Burri (2024) conducted an editorial in Interventricular septum perforation. Left bundle branch area pacing (LBBAP) was evaluated. Delayed post-operative perforation of the interventricular septum is a rare complication of left bundle branch area pacing, with an estimated incidence of 0.08-0.33%.
