To explore the feasibility of left bundle branch pacing in anatomically repaired congenitally corrected transposition of great arteries (CCTGA).
Case report of a 12-year-old patient with CCTGA after double switch operation using Rastelli repair.
Utilized three-dimensional reconstructions from cardiac CT for anatomical understanding and procedure simulation.
Pacing lead was positioned at the mid-inferior interventricular septum of the right ventricle.
Non-selective left bundle branch (LBB) capture observed with paced QRS duration improvement from 219 ms to 138 ms.
Despite initial symptomatic improvement, ventricular function did not recover sufficiently; heart transplantation was performed two months later.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Case report demonstrates that left bundle branch pacing improves ventricular function in repaired CCTGA, highlighting virtual reality's role in procedure planning.
