Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
Finally, some patients may have a radiofrequency catheter ablation, where certain areas of tissue are destroyed such that the electrical signal doesn’t propagate any more. One type of procedure is the “maze procedure” where a maze of new pathways are created to help electrical impulses move in a more consistent and predictable pattern.
A major reason for recurrence of atrial fibrillation after ablation has been the belief of electrical pulmonary vein reconnection, which has not been seen for PFA. [7] In one study, atrial fibrillation recurrence in the thermal ablation group was 39% compared to 11% in the PFA group. [8]
The system, PulseSelect Pulsed Field Ablation (PFA), is used for the treatment of atrial fibrillation (AF), a condition that is characterized by an irregular rhythm of the heart. PFA is used for ...
For TIC due to atrial fibrillation, rate control, rhythm control, and RF catheter ablation can be effective to control the tachyarrhythmia and improve left ventricular systolic function. [ 5 ] [ 9 ] For TIC due to atrial flutter, rate control is often difficult to achieve, and RF catheter ablation has a relatively high success rate with a low ...
