Contact 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 کاملContact Force and Atrial Fibrillation Ablation.
Catheters able to measure the force and vector of contact between the catheter tip and myocardium are now available. Pre-clinical work has established that the degree of contact between the radiofrequency ablation catheter and myocardium correlates with the size of the delivered lesion. Excess contact is associated with steam pops and perforation. Catheter contact varies within the left atrium ...
متن کاملContact 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 کاملThe Role Of Contact Force In Atrial Fibrillation Ablation.
During radiofrequency (RF) ablation, low electrode-tissue contact force (CF) is associated with ineffective RF lesion formation, whereas excessive CF may increase the risk of steam pop and perforation. Recently, ablation catheters using two technologies have been developed to measure real-time catheter-tissue CF. One catheter uses three optical fibers to measure microdeformation of a deformable...
متن کامل[Pulmonary vein ablation in atrial fibrillation. Initial experience].
Despite the progress in the knowledge of the pathophysiology of the atrial fibrillation (AF), the pharmacologic and non pharmacologic approach to prevent and control this arrhythmia has been shown to be discouraging. In the past few years a new type of AF has been described, of which the focal mechanism -especially bound to the pulmonary veins- allows ablation treatment through the radiofrequen...
