Long‐term efficacy and safety of radiofrequency catheter ablation of atrial fibrillation in patients with cardiac implantable electronic devices and transvenous leads

Cardiovascular Electrophysiology, 2019
Long‐term efficacy and safety are uncertain in patients with cardiac implantable electronic devices (CIED) and transvenous leads (TVL) undergoing radiofrequency catheter ablation of atrial fibrillation (AF).

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.

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

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 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.

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.

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 ...

Characteristics of atrial fibrillation patients suffering atrioesophageal fistula after radiofrequency catheter ablation

Cardiovascular Electrophysiology, 2018
Radiofrequency catheter ablation (RFCA) in atrial fibrillation (AF) patients can cause various complications and atrioesophageal (AE) fistula is one of the most catastrophic complications of RFCA.

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 ...

Ventricular Tachycardia: Pathophysiology and Radiofrequency Catheter Ablation

Pacing and Clinical Electrophysiology, 1997
Limitations of pharmacological therapy for VT have led to great interest in alternative nonpharmacological therapies. The appeal of a curative therapy for VT initially led to the search for operative techniques to identify and destroy the underlying substrate, and more recently, has resulted in the development of catheter techniques to achieve the same
