Radiofrequency catheter ablation of atrial tachycardias

American Heart Journal, 1996
Atrial tachycardias are frequently unresponsive to medical therapy. His bundle ablation has been proposed as a palliative treatment to treat symptoms and prevent development of tachycardia-mediated cardiomyopathy. Experience with catheter ablation directed at the atrial origin of the tachycardia remains limited. We reviewed the initial success rate and

Radiofrequency catheter ablation for atrial fibrillation

Journal of the American Academy of Physician Assistants, 2015
Antiarrhythmic drugs are the first-line treatment for atrial fibrillation (AF); as a result, catheter ablation usually is not considered until a patient is experiencing symptomatic AF refractory to at least one antiarrhythmic medication or is intolerant to medical therapy. For these patients, catheter ablation is shown to be more effective than medical

Percutaneous cryoablation for papillary muscle ventricular arrhythmias after failed radiofrequency catheter ablation

Cardiovascular Electrophysiology, 2018
Catheter ablation of ventricular arrhythmias (VA) from the papillary muscles (PM) is challenging due to limited catheter stability and contact on the PMs with their anatomic complexity and mobility.

Lesion characteristics between cryoballoon ablation and radiofrequency ablation with a contact force‐sensing catheter: Late‐gadolinium enhancement magnetic resonance imaging assessment

Cardiovascular Electrophysiology, 2020
Pulmonary vein isolation (PVI) lesions after cryoballoon ablation (CBA) are characterized as a wider and more continuous than that after conventional radiofrequency catheter ablation (RFCA) without the contact force (CF)‐sensing technology.

RADIOFREQUENCY CATHETER ABLATION FOR ATRIAL FIBRILLATION

Cardiology Clinics, 1997
Until recently, catheter-based radiofrequency ablation for atrial fibrillation was limited to palliative approaches of either atrioventricular node ablation or modification. It is now recognized that at least a proportion of patients with paroxysmal atrial fibrillation may be suitable for curative ablation of an underlying single arrhythmogenic focus ...

Radiofrequency catheter ablation of atrial tachycardia

Australian and New Zealand Journal of Medicine, 1995
Abstract Background: Atrial tachycardia is a relatively uncommon arrhythmia which usually responds poorly to antiarrhythmic drug therapy. Transcatheter radiofrequency (RF) ablation is a new therapeutic modality for patients with atrial tachycardia. Aim: This study analyses our early experience with the treatment of atrial tachycardia by this technique.

Radiofrequency Catheter Ablation for Cardiac Tachyarrhythmias

Annals of Internal Medicine, 1994
To review the radiofrequency ablation method, describe the technique, and discuss the indications, results, and limitations of its use in patients with cardiac tachyarrhythmias.Peer-reviewed reports in the literature by clinical investigators who use radiofrequency catheter ablation as identified by a MEDLINE search and our own experience with this ...

Treating tachyarrhythmias with radiofrequency catheter ablation

Dimensions of Critical Care Nursing, 2000
Fast, safe, and effective, radiofrequency catheter ablation is becoming more common as a treatment for tachyarrhythmias. This article describes the procedure, which patients are eligible for it, and nursing considerations before, during, and after the procedure.

Biophysical parameters of radiofrequency catheter ablation

International Journal of Cardiology, 1992
Radiofrequency catheter ablation has been shown to be an effective treatment for patients with accessory pathways in Wolff-Parkinson-White syndrome and other supraventricular tachycardias. However, the biophysical parameters used so far in vivo did not correlate to the size of myocardial lesions and provided no information about the myocardial wall ...

Radiofrequency multielectrode catheter ablation in the atrium

Physics in Medicine and Biology, 1999
We developed a temperature-controlled radiofrequency (RF) system which can ablate by delivering energy to up to six 12.5 mm long coil electrodes simultaneously. Temperature feedback was obtained from temperature sensors placed at each end of coil electrodes, in diametrically opposite positions.
