Summary
Radiofrequency catheter ablation (RFCA) effectively treats ventricular arrhythmias (VA) and premature ventricular contractions (PVC). This study shows a high success rate of 93% for RFCA in curing symptomatic VA.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Devices
Background:
- Radiofrequency catheter ablation (RFCA) is a recognized treatment for supraventricular and ventricular arrhythmias (VA).
- Assessing RFCA efficacy in VA is crucial for managing complex cardiac rhythm disorders.
Purpose of the Study:
- To evaluate the outcomes of RFCA for ventricular arrhythmias (VA) at Siriraj Hospital.
- To determine the success rate and safety of RFCA in a clinical setting.
Main Methods:
- Electrophysiologic study, including earliest endocardial activation and pace mapping, was performed.
- Radiofrequency catheter ablation (RFCA) was utilized to treat diagnosed ventricular arrhythmias (VA).
Main Results:
- Thirty patients with symptomatic VA underwent RFCA, with 33 out of 36 morphologies successfully ablated.
- The final success rate after re-ablation was 93%, with only minor complications reported.
- Procedure times were longer for left ventricular tachycardia (VT) compared to right VT.
Conclusions:
- Radiofrequency catheter ablation (RFCA) is an effective therapeutic option for ventricular tachycardia (VT) and refractory premature ventricular contractions (PVC).
- RFCA should be considered a viable alternative treatment for patients with these cardiac arrhythmias.
