Practical Approaches to Coronary Venous Ethanol Ablation for Refractory Ventricular Arrhythmias: Technique Selection and Clinical Outcomes
Authors' conclusion
In patients with VAs refractory to endocardial RFA, CVEA was associated with favorable acute and long-term outcomes, with no fatal complications. Technique selection should be tailored to the venous anatomy, with judicious ethanol volume adjustment.
Study context
- Population
- Patients with ventricular arrhythmias refractory to endocardial RFAunderwent coronary venous ethanol ablation (CVEA), of 204 consecutive patients undergoing VA ablation, 55 had ventricular arrhythmias (VAs) refractory to endocardial RFA · premature ventricular contraction (PVC) 33 · ventricular tachycardia (VT) 9
- Participants
- 42 patients
- Comparison
- PVC vs VT
- PVCn = 33
- VTn = 9
