Pulmonary vein isolation implemented by second-generation cryoballoon for treating hypertrophic cardiomyopathy patients with symptomatic atrial fibrillation: a case-control study.

ABSTRACT:

Background

Atrial fibrillation (AF) is a generally acknowledged turning-point of the natural history of hypertrophic cardiomyopathy (HCM); however, data from the cryoballoon ablation (CBA) for AF in HCM patients are relatively scarce. The study aimed to evaluate the efficacy and safety of CBA in HCM patients with AF.

Methods

We retrospectively analyzed HCM patients among 1253 patients with symptomatic AF who underwent CBA for pulmonary vein isolation in a single center. The study analyzed the AF recurrence and assessed the CBA indexes, including nadir temperature, time-to-isolation, CBA failure, pulmonary vein potentials (PVPs), and redo procedure.

Results

A total of 108 patients were included (mean age: 59.0 ± 6.9 years), 27 patients (25%) had HCM, with the median fo
