Abstract

The subject of this disclosure includes systems, devices and methods to treat a predetermined patient population for paroxysmal atrial fibrillation, the method including ablating tissue of one or more targeted pulmonary veins with one or more of a plurality of the electrodes of an independently controlled multi-electrode radiofrequency balloon catheter, the balloon catheter comprising the plurality of electrodes for radiofrequency ablation that are independently controllable; determining a predictor, based on ablation parameters of the balloon catheter, of single shot pulmonary vein isolation (PVI) success rate; and achieving, based on the predictor and step of ablating tissue, a single shot isolation PVI success rate in the isolation of all targeted pulmonary veins for the predetermined patient population.
