FIRM-Guided Catheter Ablation for Atrial Fibrillation

A former professor of medicine at the University of California, San Diego, Sanjiv Narayan, MD, PhD, is a skilled physician who has spent the last two decades working as a cardiologist. Dr. Sanjiv Narayan joined Stanford University in 2014 and has been researching to develop innovative therapies to address significant health issues such as atrial fibrillation.

For decades, atrial fibrillation has been one of the causes of stroke and heart failure in patients with heart rhythm abnormalities. It has been discovered that the abnormal heart rhythm (atrial fibrillation) is triggered and sustained by electric signals from pulmonary veins. Not long after, scientists discovered that specific localized electric signal sources in the cardiac muscles also play an essential role in atrial fibrillation episodes and can trigger and sustain dangerous heart rhythms. To that extent, a new focus seemed pertinent.

Catheter ablation targeting these abnormal signal sources in the heart is centered on hampering these signals by wounding the tissues. The tears are tiny and precisely exerted on the localized electric motors (the areas where the dangerous signals are coming from). This approach is called driver based ablation. One approach is focal impulse and rotor modulation (FIRM) - guided ablation, and others are developed by Ablacon Inc, Cardio NXT and several companies including Cartofinder. These are less invasive procedures because the catheters are directed to specific causes of the heart rhythm disorder .

Driver-guided ablation requires a reliable electrophysiological mapping system to detect the localized electric motors prior to ablation. The mapping technology is made by Ablacon, CardioNXT, Acutus, Cartofinder, and Topera Mapping Systems as widely available in the United States.
