Varian announced that the U.S. Food and Drug Administration (FDA) has granted the company Breakthrough Device Designation for its cardiac radioablation (CRA) system, currently in development as a noninvasive therapy for select patients with refractory ventricular tachycardia (VT). Varian's CRA system was designated a Breakthrough Device by the FDA because of its potential to offer a more effective treatment for select patients with refractory VT. Unlike conventional catheter ablation for VT, the Varian CRA system is being developed to enable noninvasive targeting and delivery of ablative energy across the full thickness of the myocardium. If this approach is supported by planned clinical studies it may lead to better outcomes for patients. As a noninvasive therapy, CRA procedures may prove safer and require less time than current surgical modalities.
