Trial Information

Near Zero Fluoroscopic Exposure During Catheter Ablation of Supraventricular Arrhythmias

Inclusion Criteria:

- male and female patients between 14 and 50 years of age who have received an
indication to radiofrequency catheter ablation of supraventricular arrhythmias
according to current guidelines.

Exclusion Criteria:

- atrial fibrillation or non isthmus-dependent atrial flutter

- pregnancy

- hematological contraindications to ionizing radiation exposure

- presence of complex congenital heart disease, and cardiac surgery within 1 month from

Type of Study:


Study Design:

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Outcome Measure:

reduction of ionizing radiation exposure

Outcome Description:

the NO-PARTY trial was designed to compare a non-fluoroscopic catheter ablation guided by the EnSite NavXTM mapping system with conventional catheter ablation for supraventricular tachyarrhythmias in terms of ionizing radiation exposure for both the patient and the operator

Outcome Time Frame:

1 day (radiation exposure will be evaluated at the end of procedure)
