High Radiofrequency Power for Faster & Safer Pulmonary Vein Ablation Trial

Status Completed

Clinical Trial Summary

Multicenter 1:1 randomized study. Two atrial fibrillation ablation strategies are compared: 1) conventional ablation using point-by-point radiofrequency applications with power 40 W guided by LSI > 6 or AI > 500 on the anterior aspect of pulmonary veins and power 25 W guided by LSI >5 or AI >350 on the posterior wall near the esophagus; 2) point-by-point RF applications with power set at 70 W and duration 9-10 s. The main objective of the trial is the incidence of esophageal lesions evaluated with systematic endoscopy and clinical efficacy evaluated with daily ECG transtelephonic transmissions during 1-year follow-up. Secondary objectives include total RF time and parameters of acute PV isolation efficacy (first-pass isolation, acute reconnections and dormant conduction).

Clinical Trial Description

Multicenter 1:1 randomized study: Hospital Universitario La Paz, Madrid; Hospital Clínico Universitario San Carlos, Madrid; Hospital Clínico y Provincial de Barcelona, Barcelona; Complejo Hospitalario de Navarra, Pamplona; Hospital Clínico Universitario de Valladolid; Hospital Clínico Universitario de Albacete; Hospital Clínico Universitario de Alicante; Hospital Universitario Virgen de las Nieves, Granada; Hospital La Fe, Valencia; Hospital Clínico de Valencia; Hospital Universitario Juan Ramón Jiménez, Huelva; Hospital de la Ribera, Alzira, Valencia. España. Spain. Two atrial fibrillation ablation strategies are compared: 1) conventional ablation using point-by-point radiofrequency applications with power 40 W guided by LSI > 6 or AI > 500 on the anterior aspect of pulmonary veins and power 25-40 W guided by LSI >5 or AI >350 on the posterior wall near the esophagus; 2) point-by-point RF applications with power set at 70 W and duration 9-10 s. The main objective of the trial is the incidence of esophageal lesions evaluated with systematic endoscopy and clinical efficacy evaluated with daily ECG transtelephonic transmissions during 1-year follow-up. Secondary objectives include total RF time and parameters of acute PV isolation efficacy (first-pass isolation, acute reconnections and dormant conduction). Subestudy: asymptomatic cerebral lesions detected by 1,5 T MRI <72 h after ablation. Not all centers participate in the subestydy. However, if the center participates, all patients in both ablation groups will be included in the subestudy. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
