Clinical Application of Electroanatomical Mapping in the Characterization of “Incisional” Atrial Tachycardias
Key result
Electroanatomical mapping-guided radiofrequency ablation successfully abolished inducible incisional atrial tachycardias in 90% (9 of 10) of patients with prior congenital heart disease surgery.
Why the study?
Does electroanatomical mapping-guided radiofrequency ablation successfully treat incisional atrial tachycardias in patients with prior congenital heart disease surgery?
Population
10 patients with 21 atrial tachycardias after surgical corrections of congenital heart disease.

Type
Observational (n=10)
Structured PICO
Does electroanatomical mapping-guided radiofrequency ablation successfully treat incisional atrial tachycardias in patients with prior congenital heart disease surgery?
P
Population
10 patients (6 men, 4 women, mean age 45 +/- 13.7 years) with 21 atrial tachycardias after surgical corrections of congenital heart disease (atrial septal defects n=6, tetralogy of Fallot n=4).
I
Intervention
Electroanatomical mapping to draw activation maps and guide radiofrequency (RF) ablation of the critical isthmus of reentrant circuits.
O
Outcome
Successful radiofrequency ablation of inducible tachycardias
Electroanatomical mapping is an effective tool for characterizing macroreentrant circuits and guiding successful radiofrequency ablation in patients with incisional atrial tachycardias following congenital heart surgery.
Cite This Study
Peichl et al. (2003) conducted an observational in Incisional atrial tachycardias post-congenital heart disease surgery (n=10). Electroanatomical mapping and radiofrequency ablation was evaluated on Successful radiofrequency ablation. Electroanatomical mapping-guided radiofrequency ablation successfully abolished inducible incisional atrial tachycardias in 90% (9 of 10) of patients with prior congenital heart disease surgery.
