The vMap Study
vMap® ECG Analysis Accuracy Demonstrated in Blinded, Multicenter, Independently Adjudicated Study
This blinded, multi-center, independently adjudicated study evaluated 225 patients with atrial and ventricular arrhythmias, as well as pacing. The study assessed vMap’s ability to accurately identify arrhythmia and pacing locations, comparing its results to the gold standard - successful ablation or pacing sites during an EP study.
Findings: vMap’s forward-solution computational ECG mapping exceeded pre-specified accuracy goals, demonstrating clinically actionable spatial accuracy. The results highlight vMap’s potential to support catheter-based and noninvasive arrhythmia therapies through rapid, noninvasive mapping.
The vMap Time Study
Impact of artificial intelligence arrhythmia mapping on time to first ablation, procedure duration, and fluoroscopy use
This retrospective, case-controlled study assessed whether AI-powered ECG arrhythmia mapping with vMap improves procedural efficiency by reducing time to ablation, total procedure duration, and fluoroscopy use compared to traditional methods.
By analyzing 28 vMap cases matched against historical controls based on physician, institution, arrhythmia type, and case complexity, the study demonstrated vMap’s ability to streamline workflows and reduce procedural burden without compromising clinical outcomes.
Key findings
Impact for AF
Success rates of ECG mapping for PVI + Atrial Fibrillation Drivers
Recurrent AF is common, hypothesis that ECG mapping + PVI may identify AF drivers better than PVI alone
27 study patients and 54 control patients (PVI only) with median 6-month follow-up
Patients had persistent AF, recurrent AF after prior ablation, or AF associated with atrial flutter or focal atrial tachycardia.
Key finding
Impact for VT
Outcome improvements associated with vMap in Unstable VT
Multi-center study of consecutive patients undergoing ablation for unstable VT against historical control adjusted for age, EF % and ischemic cardiomyopathy
Out of 32 consecutive patients undergoing ECG mapping guided VT ablation, 26 had unstable VT
6-month follow-up
Key findings
Radio-Ablation Planning Study Utilizing vMap
Computational ECG mapping and respiratory gating to optimize stereotactic ablative radiotherapy workflow for refractory ventricular tachycardia.
This peer-reviewed, prospective, dual-site study evaluated a non-invasive workflow using vMap to facilitate radioablation planning and improve treatment efficacy for patients with advanced structural heart disease and refractory ventricular tachycardia.
The study concluded that vMap’s 12-lead ECG mapping, combined with protocol-based respiratory gating, may help optimize radioablation planning while maintaining short-term safety and therapeutic efficacy during treatment.
