Translational Approach for Percutaneous Interventions for the Treatment of Cardiac Arrhythmias

Abstract

New translational concepts on cellular and tissue substrate of cardiac arrhythmias have been responsible for the development of non-pharmacological interventions, with important achievements compared to the conventional approach with antiarrhythmic drugs. In addition, the increasing knowledge of anatomical and electrophysiological studies, sophisticated mapping methods, special catheters, and controlled clinical trials have favored the progression of ablation of tachyarrhythmias, particularly of ventricular tachyarrhythmias and atrial fibrillation.

Balloon Cryoablation for the Treatment of Paroxysmal Atrial Fibrillation

Guilherme Fenelon et al. Frederico Scuotto Claudio Fischer Marco Antonio Perin … Marcia Makdisse Angelo Amato Vincenzo de Paola

Introduction

Radiofrequency ablation (RFA) aiming at the electrical isolation of the pulmonary vein (PV) is more effective in controlling the rhythm than drugs, especially in young individuals with symptomatic paroxysmal atrial fibrillation (AF) without structural heart disease.^– Electrical isolation is performed with point-by-point RFA around the PV, constituting a complex and lengthy procedure., Recently, technologies have been developed aiming to simplify PV isolation, among them the balloon cryoablation.^, In this approach, the cryoballoon is inflated in the PV ostium in order to completely occlude it. The release of cryoenergy cools the balloon surface, having the potential to isolate the vein with a single application. The efficacy and safety of cryoablation are similar to RFA, but the procedure is faster.^–

Although used worldwide,^– only recently cryoablation was made available in Brazil. The objective of this study was to report the first three cases performed in our country using this technology.
