Three-dimensional-mapping-guided permanent conduction system pacing in paediatric patients with congenitally corrected transposition of the great arteries
Authors' conclusion
Three-dimensional-EAM-guided LVCSP preserved RV systolic function in paediatric patients with CCTGA and AVB after short-term follow-up.
Study context
- Population
- Paediatric congenitally corrected transposition of the great arteries (CCTGA) patients with complete/advanced atrioventricular block (AVB)4 with prior epicardial pacing
- Participants
- 7 patients
- Outcome
- Preservation of systemic RV systolic function (3D EF, FAC, RV GLS)
- Follow-up
- 1-year follow-up
Methodological detailsAge 15 (9-17) years, median (25th-75th centiles), 5 DDD, 2 VVIR
- Age 15 (9-17) years, median (25th-75th centiles)
- 5 DDD, 2 VVIR
Main finding
As reported in the abstract
Systemic RV function
All patients had normal right ventricle (RV) ejection fraction (EF)
>45%
Observational data: associations, not effects.
Further findings
QRS duration · 1-year follow-up
- No significant change vs baseline; shortened vs prior epicardial pacing
Lead parameters · 1-year follow-up
- Remained acceptable despite increased ventricular threshold
Ventricular pacing
- Ventricular pacing
- >90%
Safety
- No acute/chronic complications occurred
