First Patients Enrolled in IMPRoVED-AF Study Evaluating vMap in Persistent and Recurrent AF

Vektor Medical today announced that the first patients have been enrolled in the IMPRoVED-AF clinical study. The prospective, randomized, controlled, multi-center trial is designed to evaluate the clinical benefit of using vMap®, the company’s FDA-cleared, non-invasive arrhythmia analysis technology, to guide ablation strategies beyond pulmonary vein isolation (PVI) in patients with persistent and recurrent atrial fibrillation (AF).

The first patients were enrolled at Baptist Health Lexington, a leader in cardiac care and innovation.

“Enrolling the first patient in the IMPRoVED-AF study marks an important milestone in our ongoing efforts at Baptist Health to further advance care for our patients suffering from cardiac arrhythmias,” said Dr. Gery Tomassoni, Principal Investigator and cardiac electrophysiologist at Baptist Health Lexington. “Using vMap to determine a targeted ablation strategy beyond the pulmonary veins provides an opportunity to address arrhythmia sources that were previously undetectable.”

The IMPRoVED-AF study will enroll up to 384 patients across approximately 20 centers in the U.S. and Europe. All patients receive a standard 12-lead ECG; those randomized to the intervention arm will receive additional driver ablation based on vMap’s analysis. The study's primary endpoint is freedom from AF at 12 months, with or without antiarrhythmic drugs.

Vektor’s vMap™ Technology Used Alongside SAbR Planning Software (Varian, Palo Alto, CA) for Non-Invasive Mapping and Radio-ablation of Refractory Ventricular Tachycardia

Life-threatening heart rhythm disorders such as ventricular tachycardia may be eliminated using cutting-edge, non-invasive technology as an alternative to standard invasive catheter ablation procedures, in some cases. In an abstract and associated poster published at the American College of Physicians’ Southern Regional Conference, researchers report successful use of vMap™ technology to guide stereotactic radiotherapy to destroy diseased heart tissue. Researchers report that this non-invasive mapping and ablation has “shown tremendous promise in recent years.” Importantly, for this patient, his “shock burden decreased from 34 ICD shocks in the 6 months preceding … therapy to 0 ICD shocks in the 11 months after treatment. His quality of life improved significantly, and he has resumed an active lifestyle”.

Computer-Based 12-Lead ECG Analysis Accurately Maps Ventricular Locations

Researchers, in an abstract and associated poster published in the Heart Rhythm Society’s journal Heart Rhythm, find that computer-based analysis of 12-lead ECG accurately mapped 93% of known ventricular locations to the exact ventricular segment.  The computer-based analysis required only 3 minutes, plus or minus 2 minutes, per ECG.

12-Lead ECG-Based Mapping Guides Non-Invasive Radiation Therapy

In an abstract published in the American Heart Association’s journal, Circulation, researchers conclude that a case of stereotactic radioablation of ventricular tachycardia illustrates efficacy of non-invasive 12-lead ECG mapping and radioablation in a patient who failed prior invasive VT therapies.
