Initial experience of a novel method for electrical isolation of the superior vena cava using cryoballoon in patients with atrial fibrillation.

ABSTRACT:

Background

Damage to the sinus node (SN) has been described as a potential complication of superior vena cava (SVC) isolation. There have been reports of permanent SN injury requiring pacemaker implantation during isolation of the SVC.

Hypothesis

It is safe and effective to isolate SVC with the second-generation 28-mm cryoballoon by using a novel method.

Methods

Forty-three patients (including six redo cases) with SVC-related atrial fibrillation (AF) from a consecutive series of 650 patients who underwent cryoballoon ablation were included. After pulmonary vein isolation was achieved, if the SVC trigger was identified, the SVC was electrically isolated using the cryoballoon. First, the cryoballoon was inflated in the right atrium (RA) and advanced towards the SVC-RA j
