NCT03258112

Brief Summary

Ventricular arrhythmias arising from cardiac outflow tract affect quality of life and can cause decrease in left ventricular ejection fraction. Drugs used for treating those arrhytmias may be ineffective or may have side effects. Radiofrequency catheter ablation can be used safely for treatment of outflow tract arrhythmias. There are different sites where those ventricular arrhythmias may originates, each site has different electrocardiographic characteristics, different procedural success rates and challenges in localization and ablation.

Secondary Outcomes (1)

  • Recurrence of ventricular arrhythmia after three months

    Three months

Study Arms (1)

catheter ablation

OTHER

all patients indicated for catheter ablation of RVOT or LVOT ventricular arrhythmia are included in one arm for electrophysiological diagnosis of the origin of arrhythmia then for radiofrequency catheter ablation

Procedure: Radiofrequency cardiac catheter ablation

Interventions

Radiofrequency cardiac catheter ablationPROCEDURE

procedure used for ablation of ventricular arrhythmia using catheters introduced to target sites percutaneously through venous or arterial systems using radiofrequency power
