Three-dimensional mapping can assist in targeting the distal His bundle for permanent pacing in patients with CCTGA, potentially preventing pacing-induced cardiomyopathy.
Key Teaching Points•Congenitally corrected transposition of great arteries (CCTGA) is associated with increased risk for complete atrioventricular block.•Ventricular pacing is associated with increased risk for heart failure in patients with CCTGA.•Permanent His bundle pacing prevents pacing-induced cardiomyopathy.•Three-dimensional mapping along with cardiac imaging can be helpful in targeting the distal His bundle for pacing. •Congenitally corrected transposition of great arteries (CCTGA) is associated with increased risk for complete atrioventricular block.•Ventricular pacing is associated with increased risk for heart failure in patients with CCTGA.•Permanent His bundle pacing prevents pacing-induced cardiomyopathy.•Three-dimensional mapping along with cardiac imaging can be helpful in targeting the distal His bundle for pacing.
