Uno studio sul catetere VARIPULSE in partecipanti con fibrillazione atriale persistente sottoposti a isolamento della vena polmonare e della vena cava superiore (SPAA PFA)

2 novembre 2026 aggiornato da: Biosense Webster, Inc.

Valutazione della Sicurezza ed Efficacia del Sistema di Catetere VARIPULSE™ nel Trattamento di Partecipanti con Fibrillazione Atriale Persistente Sottoposti a Isolamento delle Vene Polmonari (con o senza Isolamento della Parete Posteriore) e Isolamento della Vena Cava Superiore: Uno Studio Randomizzato Controllato

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.

Sperimentale: VARIPULSE Catheter System: PVI and SVCI

Participants with persistent atrial fibrillation (PsAF) undergoing catheter ablation for the first-time with the VARIPULSE Catheter System will undergo the ablation procedure for PVI and SVCI.

Additionally, a subset of participants will undergo a concomitant left atrial appendage occlusion (LAAO) procedure. All participants will be followed for up to 36 months post procedure.

Lasso di tempo: Up to approximately 7 days post-procedure

PAEs include early onset AEs such as esophageal perforating complications, phrenic nerve paralysis (PNP; permanent), cardiac tamponade/perforation, pulmonary vein stenosis (PVS), death (device or procedure related), stroke/ cerebrovascular accident (CVA), major vascular access, complication/bleeding, thromboembolism, myocardial Infarction (MI), transient ischemic attack (TIA), pericarditis, pulmonary edema (respiratory insufficiency), heart block, and vagal nerve injury/ gastroparesis.

Up to approximately 7 days post-procedure
Freedom from Documented (Symptomatic and Asymptomatic) Atrial Tachyarrhythmia Episodes
Lasso di tempo: Day 61 up to Day 180

Number of participants reporting freedom from documented (symptomatic and asymptomatic) atrial tachyarrhythmia (that is, atrial fibrillation or atrial tachycardia or atrial flutter [AF, AT or AFL] of unknown origin) episodes based on electrocardiographic data and freedom from acute procedural failure, repeat ablation failure, surgical treatment for AF/AT/AFL, non-study catheter (NSC) failure, antiarrhythmic drug (AAD) failure and any direct current (DC) cardioversion procedure.

Day 61 up to Day 180

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Freedom from Documented (Symptomatic and Asymptomatic) Atrial Tachyarrhythmia Episodes
Lasso di tempo: 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.

Day 61 up to Day 365
Change From Baseline in Quality of life, As Measured by the Total Atrial Fibrillation Effect on Quality-of-Life (AFEQT) Score
Lasso di tempo: 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
