Contact 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 کاملAssessing epicardial substrate using intracardiac echocardiography during VT ablation.
BACKGROUND Intracardiac echocardiography (ICE) has played a limited role in defining the substrate for ventricular tachycardia (VT). The purpose of this study was to assess whether ICE could identify abnormal epicardial substrate in patients with nonischemic cardiomyopathy (NICM) and VT. METHODS AND RESULTS We studied 18 patients with NICM and recurrent VT who had abnormal echogenicity identi...
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 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...
