STrategies for Catheter Ablation of peRsistent Atrial Fibrlllation
NCT04428944 · View on ClinicalTrials.gov ↗
Study Summary
The objective of this study is to compare the efficacy of three different ablation strategies in patients with persistent AF: 1. PV antral isolation alone (PVAI) 2. PV antral isolation plus ablation of drivers (PVAI+drivers) 3. PV antral isolation plus isolation of posterior wall (PVAI+box) All three strategies will employ contemporary catheter ablation technology using more efficient open irrigated tip cooling and contact force sensing.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04428944
The ClinicalTrials.gov registry entry for NCT04428944 describes a study currently listed as active not recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 617 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is McGill University Health Centre/Research Institute of the McGill University Health Centre, which has 36 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Atrial Fibrillation appearing as the primary indexed condition, and to 3 interventions — of which Wide Circumferential Pulmonary Vein Antrum Isolation (PVAI) is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04428944 reports 20 study locations spanning 8 distinct geographic areas — top geographies include Other, British Colombia, Quebec. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
