Implication

May aid pre-transseptal focus localization in paroxysmal AF; hypothesis-generating pending prospective validation.

Structured PICO

Does an algorithm using endocardial atrial activation sequences predict the location of initiating foci of AF before transseptal procedure in patients with paroxysmal AF?

Population

75 patients (60 men and 15 women, age 68 +/- 12 years) with frequent episodes of paroxysmal atrial fibrillation referred for radiofrequency ablation.

Intervention

Algorithm using endocardial atrial activation sequences from right atrial, His-bundle, and coronary sinus catheters to predict the location of initiating foci of AF before transseptal procedure.

Comparator

Confirmed location of initiating foci by successful ablation.

Outcome

Accuracy of predicting the location of initiating foci of AF.surrogate

Endocardial atrial activation sequences from right atrial, His-bundle, and coronary sinus catheters can accurately predict the location of initiating foci of AF before transseptal procedure, potentially facilitating mapping and ablation.
