New data indicates that more than 80% of patients who received radiofrequency-based ablation were free from any form of atrial arrhythmia at a one-year followup. Radio-Frequency Ablation Helped 82 ...
After 12 months, participants receiving catheter ablation were more likely to be free of atrial fibrillation, and less likely to need cardioversion. However, the evidence quality ranged from moderate to very low [ 4 ] A 2006 study, including both paroxysmal and non-paroxysmal atrial fibrillation, found that the success rates are 28% for single ...
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [11] [12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [4]
The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the atria.
With those caveats in mind, it can be said that reported short-term freedom from atrial fibrillation following the radiofrequency ("Wolf") procedure ranges from 67% to 91% [8] [9] [11] with longer-term results in a similar range, but limited primarily to patients with paroxysmal atrial fibrillation. [19] [20]
[6] [7] It is performed without surgery, by using radiofrequency catheter ablation with one-day hospital. [citation needed] The results up to 100 months follow-up are showing better outcome than clinical measures or pacemaker implantation with changing the tilt-test on to normal and by absence of syncope in more than 90% of patients without ...
Premature atrial contractions (PACs) are common in the general population, and increase with age. [5] Over 99% of individuals in the general population will have at least one PAC in a 24 hour period. [6] Many PACs can indicate increased risk of atrial fibrillation and/or ischemic stroke. [6]
