Brief Summary

Our observational study aim to to evaluate the incidence of Tachyarrhythmia in patients with congenital heart diseases (corrected/non corrected) and the effectiveness of catheter ablation.RF catheter ablation was performed to all patients and follow up for recurrence was done for one year.

Conditions

Congenital Heart Disease; Arrhythmia; Ablation of Arrhythmias

Keywords

Congenital heart disease, Catheter ablation, arrhythmia, Radiofrequency, 3D Mapping, tachycardia.; Outcome

Outcome Measures

Primary Outcomes (2)

• the rate of acute success of catheter ablation

  defined as termination of the clinical arrhythmia with non-inducibility of this clinical arrhythmia during Catheter ablation

  From timing of catheter ablation till about one hour

• rate of recurrence of tachyarrhythmias after catheter ablation

  one year

Secondary Outcomes (1)

• The types of Tachyarrhythmia in patients with congenital heart diseases

  One year
