Trial Outcomes & Findings for Advisor HD Grid Observational Study (NCT NCT03733392)

NCT ID: NCT03733392

Last Updated: 2024-04-16

Results Overview

The rate of acute success is defined as the percent of subjects who received HD Grid mapping and RF energy delivery according to label resulting in acute termination of clinical arrhythmia, defined by termination to sinus rhythm (SR) (or AT if being treated for PersAF) or non-inducibility of clinical arrhythmia after ablation (cardioversion allowed prior to inducibility attempt).

Participant Flow

372 of the 379 enrolled subjects started and completed the ablation procedure. The remaining 7 subjects (5 PersAF, 2 VT) were withdrawn prior to procedure due to presence of thrombus, mapping system incompatible with the HD Grid, subject withdrawal of consent, and/or early enrollment closure.

PRIMARY outcome

Timeframe: PersAF (12 months), VT (6-months)

VT: Subjects indicated for ablation to treat VT in which the HD grid catheter was inserted, and RF energy was applied according to label who completed their 6-month follow-up visit.

For PersAF, the rate of long-term success rate is defined as the percent of subjects who receive HD Grid mapping and RF energy delivery according to label and have had freedom from all atrial arrhythmias (AF/AFL/AT) greater than 30 seconds (as documented by 48-hr Holter at 12-month follow-up) and a new or increased dose in class I/III antiarrhythmic drug (AAD). For VT, the percent of subjects who receive HD Grid mapping and RF energy delivery according to label and have had freedom from recurrence of sustained monomorphic VT and a new or increase dose in class I/III AAD at 6-month follow-up. The percent of subjects who are free from the pre-defined endpoints on or off class I/III AADs is also reported.

Quality of life (QOL) validated by EQ-5D-5L and Atrial Fibrillation Effect on Quality-of-Life (AFEQT) in PersAF subjects at Baseline, 6 and 12 months after receiving HD Grid mapping and RF ablation. The visual analogue score (VAS) component of the EQ-5D-5L questionnaire indicate how good or bad a subject's health was on the day the questionnaire was administered. 100 means the best health you can imagine and 0 means the worst health you can imagine. There are 4 subscales that contribute to the Overall AFEQT Score (Symptoms, Daily Activities, Treatment Concern, and Treatment Satisfaction). The overall AFEQT score is calculated using the first 3 domains and ranges from 0 = worst to 100 = best QoL. Patient satisfaction with treatment is not considered to be a part of a patient's health status and is not included in the summary score calculation.
