Intracardiac Echocardiography to Assist Anatomical Isthmus Ablation in Repaired Tetralogy of Fallot Patients With Ventricular Tachycardia: Technique and Outcomes
Authors' conclusion
ICE improves ablation of the anatomical isthmus for sustaining VT in patients with repaired TOF by demonstrating the individual anatomy but does not improve long-term outcomes.
Study context
- Population
- Adults with repaired tetralogy of Fallot undergoing ventricular tachycardia (VT) ablation, 2017–2022VT ablations in 23 patients
- Participants
- 27 adults
- Exposure
- Intracardiac echocardiography (ICE)-guided VT ablation vs electroanatomical mapping only
- ICEn = 16/27
- No ICEn = 11/27reference
- Outcome
- Localization and ablation of the anatomical isthmus
Main finding
As reported in the abstract
Ability to localize and ablate the anatomical isthmus

Observational data: associations, not effects.
Further findings
Long-term freedom from VT
P = 0.901
Procedural time
P = 0.399
Fluoroscopy time
P = 0.864
Safety
| Outcome | ICE | No ICE | P value |
|---|---|---|---|
| Major complications | 6% | 0/11 events | P = 1.000 |
