WebJan 10, 2024 · The CAPLA (Catheter Ablation for Persistent Atrial Fibrillation: A Multicenter Randomized Trial of Pulmonary Vein Isolation vs PVI With Posterior Left Atrial Wall Isolation) trial studied the effect of ablation in 338 patients with symptomatic persistent AF of less than 3 years’ duration for which 1 or more antiarrhythmic drugs had failed. 6 … Catheter ablation involves advancing several flexible catheters into the patient's blood vessels, usually either in the femoral vein, internal jugular vein, or subclavian vein. The catheters are then advanced towards the heart. Electrical impulses are then used to induce the arrhythmia and local heating or freezing is used to ablate (destroy) the abnormal tissue that is causing it. Originally, a DC impulse was used to create lesions in the intra-cardiac conduction system. However, due to a hi… salary scale astiWebCryoballoon Ablation. For cryoballoon pulmonary vein isolation, a special deflated balloon (cryoballoon) is introduced into the left atrium then inflated and placed at the mouth of the pulmonary veins. During the ablation the cryoballoon produces very low temperatures, freezing the tissue in contact with the balloon perimeter. things to do in flower mound
