Biosense Webster, a Division of Johnson & Johnson Medical NV/SA, and a leader in the diagnosis and treatment of cardiac arrhythmias, recently presented new data evaluating the one-year outcomes of atrial fibrillation (AF) ablation using the CARTO 3 System CARTO VISITAG Module with ablation index at Venice Arrhythmias 2017. Patients were followed for a year and monitored for instances of atrial fibrillation, atrial flutter and atrial tachycardia via Holter electrocardiographs at three, six and 12 months.
The results, published in the Journal of American College of Cardiology: Clinical Electrophysiology, show that after 12 months, 92.3% of patients (n=130) were free from arrhythmia (atrial fibrillation, atrial flutter and atrial tachycardia).1
Atrial fibrillation affects around 14 million people across Europe, the Middle East and Africa2 – with patients suffering from this condition said to have an increased risk of mortality and a five-fold increased risk of having a stroke3. “Atrial fibrillation is the new epidemic of modern society; both underdiagnosed and poorly treated,” said Gabriele Fischetto, Vice President of Johnson & Johnson Cardiovascular Specialty Solutions in EMEA. “With a 21-year legacy of expertise in electrophysiology, our mission at Biosense Webster is to deliver breakthrough innovations that help restore a patient’s regular heart rhythm and quality of life. This new evidence gives us a strong indication that we are making great strides in helping to cure this debilitating disease.”
Biosense Webster’s CARTO 3 System is an advanced imaging system that uses electromagnetic technology to create real-time 3D maps of a patient’s cardiac structures. The addition of the CARTO VISITAG Module with Ablation Index provides a visual indication based on the integration of stability, power, contact force and time parameters to be displayed on the CARTO 3 System. This index was developed to simplify and standardise the workflow for ablating patients with paroxysmal atrial fibrillation (PAF) and support electrophysiologists using the CARTO SMARTTOUCH Technology, in reproducing their own successful ablation strategy to achieve pulmonary vein isolation.
The author of the study, M. Duytschaever, Heart Division Az Sint-Jan Hospital, Belgium, commented: “With the increased risk of morbidity and mortality, it is vital that physicians have access to effective treatments for AF. The results published in this paper clearly demonstrate the important role of a reproducible workflow for PAF and of the CARTO 3 System CARTO VISITAG with Ablation Index. This single-procedure solution not only offers a >90%1 success rate after one year, but the technology has also improved my procedure efficiency by reducing operating time by almost 30% and radiofrequency ablation time by almost 40%.”
Important Information: The CARTO VISITAG Module provides access to data collected during the application of RF energy. The data does not indicate the effectiveness of RF energy application. Refer to the CARTO 3 System Instructions For Use for indications, contraindications, side effects, suggested procedure, warnings and precautions as well proper recommendations and settings.
The Ablation Index should not be used to replace standard handling precautions or other clinically accepted endpoints for RF applications such as reduction of IC signals, impedance drop, temperature, force, etc.
