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.
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).
Symplicity HTN-1 [3] looked at outcomes in 153 patients that underwent catheter-based renal denervation. Three-year follow-up data have demonstrated an average blood pressure reduction of -33/-19mm Hg. Symplicity HTN-2 was a randomized, [2] controlled trial that compared 54 control patients with 52 patients who underwent catheter-based renal ...
ablation equipment to destroy abnormal tissue; an electroanatomic mapping system that tracks and records the catheter position in 3D and associated electrical signals; ready access to cardiac medications such as adenosine, atropine, dopamine, and isoproterenol; ready access to an assortment of introducer sheaths and catheters
Cryoablation is used in two types of intervention for the treatment of arrhythmias: (1) catheter-based procedures and (2) surgical operations. A catheter is a very thin tube that is inserted into a vein in the patient’s leg and threaded to the heart where it delivers energy to treat the patient’s arrhythmia.
Cardiac catheterization (heart cath) is the insertion of a catheter into a chamber or vessel of the heart.This is done both for diagnostic and interventional purposes. A common example of cardiac catheterization is coronary catheterization that involves catheterization of the coronary arteries for coronary artery disease and myocardial infarctions ("heart attacks").
Once a catheter is in place, it can be used to perform a number of procedures including angioplasty, PCI (percutaneous coronary intervention) angiography, transcatheter aortic valve replacement, balloon septostomy, and an electrophysiology study or catheter ablation.
[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 ...
