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 (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 ]
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 ...
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.
The Cox maze procedure, also known as maze procedure, is a type of heart surgery for atrial fibrillation. "Maze" refers to the series of incisions arranged in a maze -like pattern in the atria . Today, various methods of minimally invasive maze procedures, collectively named minimaze procedures , are used.
