Long-Term Freedom From Ventricular Arrhythmias in Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) With Endocardial Only Ablation: Predictors of Success
Authors' conclusion
Long-term VT-free survival can be achieved in over half of ARVC patients following ENDO-only VT ablation, increasing to over 75% if VT noninducibility is achieved.
Study context
- Population

- Participants
- 74 patients
- Outcome
- Freedom from any recurrent sustained VT after the last endocardial (ENDO)-only ablation
Methodological detailsconsecutive patients
- Consecutive patients
