Structured PICO

Does percutaneous catheter ablation effectively and safely treat various supraventricular and ventricular tachyarrhythmias?

P
Population
187 consecutive patients with various supraventricular and ventricular tachyarrhythmias (including WPW syndrome, AVNRT, atrial flutter, atrial tachycardia, medically refractory atrial fibrillation, idiopathic VT, and sustained VT associated with structural heart disease)
I
Intervention
Closed-chest transcatheter electrical ablation (catheter ablation)
O
Outcome
Overall final success rate of the ablation procedure

Catheter ablation is a highly effective and safe curative therapy for a wide range of supraventricular and ventricular tachyarrhythmias, achieving an overall success rate of nearly 90%.

Limitations

  • Single center experience
  • Early learning curve affected initial success rates
  • Lack of a control group
