Abstract

A new method of PVs disconnection for ablation of atrial fibrillation and some preliminary results are reported. The data have been collected at San Donato Hospital in Milan, with the collaboration of the NASPE-Heart Rhythm Society Fellow in Bologna, Chen Liying MD. From the present experience the AA. can conclude that, using a prospectively designed multi-step catheter approach, late conduction recurrence, across a disconnecting composite RF lesion, can be observed in about 80% of the targeted PVs. Furthermore, after re-ablation, a second recurrence can be observed in about 70% of targeted PVs. The AA. conclude that the high rate of late conduction recurrence may contribute significantly to clinical recurrences in patients with a Fib, undergoing catheter ablation, aiming at disconnection of multiple PVs.
