Live presentation at ESC Congress 2021 showcases initial clinical experience with the novel pulsed field ablation system for paroxysmal atrial fibrillation ablation, resulting in acute procedural success in 100% of study subjects with no procedural adverse events1***
IRVINE, CA – August 27, 2021 – Biosense Webster, the global leader in cardiac arrhythmia treatment and part of the Johnson & Johnson Medical Devices Companies*, announced today that data from the inspIRE clinical trial was presented at the ESC Congress 2021, organized by the European Society of Cardiology, taking place virtually from August 27-30. inspIRE is a prospective, multi-center, non-randomized study evaluating the safety and effectiveness of the investigational VARIPULSE™ Catheter and TRUPULSE™ Generator, which uses pulsed field ablation (PFA) in treating symptomatic drug refractory recurrent paroxysmal (intermittent) atrial fibrillation, with planned enrollment of up to 550 patients.
Today at ESC Congress 2021, initial results of 35 subjects were presented by Dr. Tom de Potter**, MD, FEHRA, Associate Director, Cardiovascular Center Department of Cardiology, Electrophysiology Section at OLV Hospital. The data showed acute procedural success (pulmonary vein isolation) was achieved in 100% of the study subjects with no procedural adverse events. Additionally, the findings agree with prior observations of the tissue-selectiveness of PFA in preclinical studies2,3,4,5 and the study exhibited low procedure time of 82.4±20.0 minutes. The pivotal phase of the study will continue to evaluate the 12-month safety and effectiveness.1***
"Pulsed field ablation marks a new era of treating atrial fibrillation for electrophysiologists. These positive results are exciting as we continue to evaluate the safety and efficacy of PFA and bring this new approach forward," said Dr. de Potter. "I am encouraged by this data and looking forward to seeing continued results so that we can help bring safer, more efficient treatments to our atrial fibrillation patients.”
PFA represents an emerging approach to treating atrial fibrillation. This technique utilizes a controlled electric field to ablate and scar cardiac tissue through a process called irreversible electroporation (IRE). As it does not rely on thermal effects to ablate target cardiac tissue, IRE offers the potential to reduce the risk of esophageal, pulmonary vein and phrenic nerve injury. The investigational VARIPULSE Catheter is a steerable, multi-electrode, catheter enabling cardiac electrophysiological mapping (stimulating and recording) and ablation functionalities through the investigational TRUPULSE Generator.
“These promising inspIRE study results mark an important first step in evaluating the potential of this novel treatment option to patients suffering from cardiac arrhythmias,” said Uri Yaron, Worldwide President, Biosense Webster, Inc. “We’re committed to the electrophysiology community and transforming the types of treatments they can offer patients. We look forward to seeing additional results as this trial continues.”
In September 2020, Biosense Webster announced that it had enrolled and treated the first patients in the inspIRE clinical study in Europe****, evaluating safety and effectiveness of the VARIPULSE Catheter and TRUPULSE Generator. VARIPULSE Catheter is an investigational technology and is not approved by regulatory bodies in any market today. To learn more about the inspIRE study, visit clinicaltrials.gov. Registration NCT04524364.
Atrial fibrillation (AF) is the most common type of cardiac arrhythmia, affecting an estimated 33 million people globally.6 Estimates state that by 2030 the number of people with AF is projected to increase by up to 70 percent.7
