Remote Magnetic Versus Manual Navigation-guided Ablation for Non-outflow Tract Premature Ventricular Contractions: a Prospective, Randomized, Controlled Trial

Department of Cardiology, Shanghai Ruijin Hospital, Shanghai Jiao Tong University School of Medicine

This prospective, randomized, controlled trial is designed to compare the safety and efficacy of remote magnetic navigation-guided ablation for ventricular premature complexes arising from non-outflow tracts with manual control navigation.

Inclusion Criteria:

1. non-outflow tract PVCs
2. Holter>10,000/24h or PVCs load>10%
3. the first ablation procedure
4. failure of at least one AAD to treat PVCs before ablation

Exclusion Criteria:

1. PVC ablation history
2. HF with NYHA IV
3. 3 months prior to AMI or PCI
4. Cardiac thrombosi
5. Hyperthyroidism
6. Pregnancy
