Three-dimensional mapping–guided permanent His bundle pacing in a patient with corrected transposition of great arteries

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...
