Contact force technology in catheter ablation of atrial fibrillation
Catheter ablation of atrial fibrillation (AF) has an indisputable value in the treatment of patients with symptomatic drug refractory AF. Nowadays, special interest is paid to improve the efficacy and the safety of the procedure and new approaches allowing better understanding of the lesions creation and its control have been developed. A lot of factors including power and duration of energy de...
متن کاملContact Force Assessment In Catheter Ablation Of Atrial Fibrillation.
The efficacy of catheter ablation of atrial fibrillation (AF) remains limited. Increase of success would require more durable lesions without increased risk of complications, such as of steam pop and cardiac perforation. Recently, novel technologies have been developed to estimate real-time catheter-tissue contact force (CF). This paper reviews three available tools for assessment of CF and dat...
متن کاملUse of the new contact force sensing ablation catheter dramatically reduces fluoroscopy time during atrial fibrillation ablation procedures
OBJECTIVES To study the impact of contact force (CF) sensing on fluoroscopy, procedure, left atrial (LA) and ablation times and number of ablations during atrial fibrillation (AF) ablation. BACKGROUND Catheter ablation is an effective treatment for symptomatic AF. Recently a new ablation catheter providing real-time CF has been approved for use. METHODS A nested case-control study was perfo...
متن کاملContact force mapping during catheter ablation for atrial fibrillation: procedural data and one-year follow-up
INTRODUCTION Pulmonary vein isolation (PVI) is the state-of-the-art treatment of atrial fibrillation (AF). Pulmonary vein reconnection is one of the main mechanisms of AF recurrence after ablation. Catheter-tissue contact is essential for effective ablation lesions. The aim of this study was to evaluate the impact of catheter contact monitoring during PVI on AF recurrence rate. MATERIAL AND M...
متن کاملThe symbiosis of contact force catheter use for hybrid ablation for atrial fibrillation
OBJECTIVE Reconduction across an ablation line is a common reason for arrhythmia recurrence over time. The hybrid procedure combines epicardial ablation of the pulmonary vein (PV) and creation of a box lesion with endocardial touch-ups for any electrical gaps. A high contact force (CF) between the ablation tip and cardiac tissue may increase the risk of thrombus formation, catheter tip charring...
