Reduction of myocardial necrosis using "CLOSE" protocol during pulmonary vein isolation-Preliminary results from ACTIVE-AF trial.

ABSTRACT:

Background

New protocols of pulmonary veins isolation (PVI) result in easier and more efficient procedure performance. Ablation index (AI) is the novel tool which helps to achieve transmural lesions during catheter ablation. However, benefit of this protocol in the reduction of myocardial injury is still not known.

Purpose

The aim of the study was to compare myocardial injury during catheter ablation using standard and AI protocol.

Methods

To the analysis we included 24 patients with paroxysmal atrial fibrillation, who underwent radiofrequency catheter PVI using CARTO system (Biosense Webster, Inc). In all patients cardiac troponin I (cTnI) levels were assessed before and 24 hours after the procedure. In 12 patients PVI was performed using continuous applications (dra
