Presentation details results from Biosense Webster’s global, multicenter STELLAR study
Irvine, CA – February 3, 2023 – Biosense Webster, Inc., a global leader in cardiac arrhythmia treatment and part of Johnson & Johnson MedTechi, announced that positive results from the company-sponsored STELLAR study were presented as a late breaker, titled “Pulmonary Vein Isolation of Paroxysmal Atrial Fibrillation with Multielectrode Radiofrequency Balloon Catheter: Results from the Global, Multicenter, STELLAR Study,” at the 28th Annual International AF Symposium.
The STELLAR study investigated the safety and efficacy of pulmonary vein isolation (PVI) using the HELIOSTAR™ Balloon Ablation Catheter in drug refractory symptomatic paroxysmal atrial fibrillation (AFib). This study is the largest clinical study to date with 12-month follow-up data for HELIOSTAR™ Balloon Ablation Catheter.
In the analysis, acute PVI was achieved in 98.8% of subjects, and in 93.0% without additional use of focal catheters. Majority of PVIs were achieved without needing focal touch-up. Primary effectiveness at 12 months was 67.7% and >90% of patients were free from repeat ablation at 12 months. In addition, the rate of clinical success – defined in the study as freedom from 12-month symptomatic atrial arrhythmia recurrence – was 77.7%.1
“With the growing prevalence of AFib, it is important that innovative tools are evaluated in various markets and patient populations to deliver value to patients across regions,” said Sandeep Goyal, M.D., FHRS, Director, Electrophysiology Lab, Piedmont Atlanta Hospital, who served as an investigator in the STELLAR studyii. “The results of this study provide further evidence of how RF balloon catheters can be an important tool for electrophysiologists when treating AFib.”
The STELLAR Study was an FDA-regulated investigational device exemption study conducted in the US, China and Italy to assess the safety and efficacy of PVI using the HELIOSTAR™ Balloon Ablation Catheter in drug refractory symptomatic paroxysmal AFib.2
The HELIOSTAR™ Balloon Ablation Catheter is the first radiofrequency balloon ablation catheter approved in EMEA for cardiac ablation. The HELIOSTAR™ Balloon Ablation Catheter is fully integrated with the CARTO™ 3 System, enabling an efficient, customizable, and reduced fluoroscopy workflow for PVI.3 HELIOSTAR™ Balloon Ablation Catheter is not approved in the US.
“Biosense Webster is committed to working with the EP community to advance safe, effective and efficient tools to treat cardiac arrhythmias, so that people with AFib can live the lives they want,” said Anthony Hong, Vice President, Preclinical and Clinical Research and Medical Affairs, Biosense Webster, Inc. “We are pleased that this analysis from the STELLAR study reinforces the value of the HELIOSTAR™ Balloon Ablation Catheter in treating drug refractory symptomatic paroxysmal atrial fibrillation.”
