Contact force sensing for atrial fibrillation ablation | 合法醫療器材資訊網

The use of catheter ablation for the treatment of symptomatic atrial fibrillation (AF) has increased significantly over the past decade.  Cardiac electrophysiologists are continually trying to refine and improve procedural outcomes for patients having catheter ablation for AF. Pulmonary veins (PVs) play a dominant role in the pathophysiology of AF and consequently, pulmonary vein isolation (PVI- electrical isolation of the pulmonary veins from the left atrium) is the cornerstone of catheter ablation therapy for all types of AF. Techniques and tools have been refined over the years to ensure the procedure is safe and effective, but technological advances continue unabated in the search to improve both safety and patient outcomes (1). Nevertheless, the Achilles heel of catheter ablation for AF is the rate of recurrence of atrial tachyarrhythmias, the predominant cause of which has been shown ...
