Key result
3D mapping-guided right bundle branch pacing proves feasible with stable parameters in ccTGA.
Why the study?
The ideal pacing strategy for patients with congenitally corrected transposition of great arteries and bradycardia remains challenging and various pacing modalities have been documented without consensus.
Population
Three patients with ccTGA and symptomatic complete heart block
Comparison
Right bundle branch pacing with 3D mapping versus conduction system pacing with additional CS lead in selected patients
Design
Prospective case series with 3D electroanatomical mapping guidance
Follow-up
Short-term follow-up

May enable physiological pacing in ccTGA with heart block; leaves open long-term efficacy and safety in larger cohorts.

Namboodiri et al. (2022) conducted a case report in Congenitally corrected transposition of great arteries (ccTGA) with complete heart block (n=3). 3D electroanatomical mapping guided right bundle branch pacing was evaluated on Feasibility of permanent physiological pacing (stable lead positions and adequate thresholds). Three-dimensional electroanatomical mapping guided right bundle branch pacing is feasible in patients with congenitally corrected transposition of great arteries, achieving stable lead parameters.
