Key result
Biatrial electroanatomic and entrainment mapping delineated IART circuits in Mustard patients, identifying the tricuspid annulus as the main barrier and enabling successful ablation in 86% of IARTs.

Does biatrial electroanatomic mapping and entrainment mapping facilitate delineation and ablation of IART circuits in patients with atrial tachyarrhythmias after Mustard operation?
Biatrial electroanatomic mapping combined with entrainment mapping facilitates delineation of IART circuits and enables successful individualized ablation strategies in patients after Mustard operation.
Zrenner et al. (2003) conducted an observational in Intra-atrial reentrant tachycardia after Mustard operation (n=12). Biatrial electroanatomic mapping and entrainment mapping was evaluated on Successful ablation of IARTs. Biatrial electroanatomic and entrainment mapping delineated IART circuits in Mustard patients, identifying the tricuspid annulus as the main barrier and enabling successful ablation in 86% of IARTs.
