AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with hypertrophic cardiomyopathy without outflow blockage who also have persistent atrial fibrillation that medicines do not control.
- Age
- 18 years or older
- Sex
- All sexes
- Disease stage
- Hypertrophic cardiomyopathy with heart wall thickness of 15 mm or more (13 mm or more if the gene test is positive), peak outflow gradient under 30 mmHg, and persistent atrial fibrillation lasting more than 7 days and less than 3 years, with symptoms despite drugs.
- Earlier treatment
- Medicines for atrial fibrillation have not controlled symptoms. No earlier ablation.
Main reasons for not taking part
- Left atrium larger than 60 mm
- Left ventricular ejection fraction of 40% or less
- Cannot take blood-thinning medicine
- Ischaemic stroke within 2 months
- Earlier ablation, chest surgery or chest radiotherapy

- Original description
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.Read full original descriptionShow less
Concomitant Hybrid Versus Catheter Ablation for Reinforcing Therapeutic Effect of Atrial Fibrillation With Hypertrophic Cardiomyopathy
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.
Inclusion: Patients' age is ≥18 y; 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); Non-obstructed left ventricular outflow obstruction with peak gradients <30mmHg; Concomitant with persistent atrial fibrillation (7 days<sustained episode lasting<3 years) with drug-refractory symptoms; Be able to understand the contents of the trial, and provide written informed consent to participate in this investigation.
Exclusion: Concomitant with left atrium or left atrial appendage emboli; Concomitant with a coronary or valvular disease that indicates intervention; Previous ablation history; Concomitant with bacteremia or at an active phase of infection; Ischaemic stroke within 2 months; End-staged kidney failure; Anatomically not suitable for thoracoscopic surgery(history of chest surgery or radiotherapy, etc.); Left ventricular ejection fraction ≤40%; Pregnant or breastfeeding, or women of childbearing age not using a reliable contraceptive method; Patients with left atrial size >60 mm (2-dimensional echocardiography, parasternal long-axis view); Contraindicated to systemic anticoagulation; Uncontrolled hyper/hypothyroidism; Concomitantly involved in other trials; Unwilling or unable to comply with all peri-ablation and follow-up requirements.
