Een onderzoek naar de VARIPULSE-katheter bij deelnemers met persisterend atriumfibrilleren die pulmonale vene- en vena cava superior-isolatie ondergaan (SPAA PFA)

2 november 2026 bijgewerkt door: Biosense Webster, Inc.

Beoordeling van de veiligheid en effectiviteit van het VARIPULSE™ kathetersysteem bij de behandeling van deelnemers met persisterend atriumfibrilleren die pulmonale veneïsole (met of zonder isolatie van de achterwand) en superieure vena cava-isolatie ondergaan: een gerandomiseerde gecontroleerde studie

The purpose of this study is to assess how safe VARIPULSE catheter system is for treatment of a heart rhythm disease called persistent atrial fibrillation (PsAF) in participants who are having a catheter ablation procedure (treat heart rhythm disease). This includes isolation of pulmonary vein and superior vena cava (heart veins; pulmonary vein isolation [PVI] and superior vena cava isolation [SVCI]), with or without another technique called posterior wall isolation (PWI). Also, to assess how safe it is for participants who are having a catheter ablation procedure and at the same time receiving another procedure called left atrial appendage occlusion (LAAO; to reduce stroke risk). Additionally, to assess how well VARIPULSE catheter system works over a long period of time for treatment of PsAF in participants undergoing catheter ablation for PVI, SVCI and SVCI+PWI.

Tijdsspanne
Freedom from Documented (Symptomatic and Asymptomatic) Atrial Tachyarrhythmia Episodes
Tijdsspanne: Day 61 up to Day 365

Number of participants reporting freedom from documented (symptomatic and asymptomatic) atrial tachyarrhythmia (that is, AF, AT or AFL of unknown origin) episodes based on electrocardiographic and freedom from acute procedural failure, repeat ablation failure, surgical treatment for AF/AT/AFL, NSC failure, AAD failure and any DC cardioversion (DCCV) procedure.

Change From Baseline in Quality of life, As Measured by the Total Atrial Fibrillation Effect on Quality-of-Life (AFEQT) Score
Tijdsspanne: Baseline, at 12 months post-procedure

The AFEQT uses a questionnaire to evaluate symptoms, daily activities and treatment concerns participants have related to atrial fibrillation. An overall AFEQT score ranges from 0 to 100. A score of 0 corresponds to complete disability (or responding "extremely" difficult to all questions answered), while a score of 100 corresponds to no disability (or responding "not at all" limited, difficult or bothersome to all questions answered). A positive change in score corresponds to improvement in AF symptoms.
Baseline, at 12 months post-procedure
