Overview
The goal of this clinical trial is to compare the rhythm control effect in hypertrophic non-obstructive patients with non-paroxysmal atrial fibrillation by either concomitant catheter endocardial and thoracoscopic epicardial ablation or catheter ablation alone. The study aims to see if concomitant hybrid ablation can more effectively achieve rhythm control effect than catheter ablation alone in non-paroxysmal atrial fibrillation patients with hypertrophic cardiomyopathy.
Description
After informed consent, 66 eligible admissions will be recruited in 2 centers. Eligible participants will be randomly divided (1:1) into either hybrid or catheter ablation arms, looking for a primary outcome of 1-year freedom from atrial arrhythmias.
Eligibility
Inclusion Criteria:
1. Patients' age is ≥18 y
2. Clinically diagnosed hypertrophic cardiomyopathy (any left ventricular wall segment thickness ≥15 mm in genetical negative (or unknown genetical status) patients or ≥13mm in genetical positive ones-as measured by any imaging technique (echocardiography, cardiac magnetic resonance imaging or computed tomography)-that is not explained solely by loading conditions)
3. Non-obstructed left ventricular outflow obstruction with peak gradients \<30mmHg
4. Concomitant with persistent atrial fibrillation (7 days\
