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.

Biosense Webster’s Qdot Micro™ Radiofrequency Ablation Catheter

Future Cardiology, 2021
The QDOT Micro™ catheter (Biosense Webster, Inc., CA, USA) is a new radiofrequency ablation catheter based on the SmartTouch SF™ (Biosense Webster, Inc.). It combines diffuse external irrigation with six thermocouples located within the outer metal shell and three additional microelectrodes in a 3.5 mm-tip contact force radiofrequency catheter.

Embolic complications after radiofrequency catheter ablation

The American Journal of Cardiology, 1994
Abstract Although radiofrequency catheter ablation of accessory pathways is very efficacious and the procedure is well tolerated with a relatively low risk of serious complications, some concern is warranted for ablations in the left heart. The risk of systemic embolism may be quite significant despite heparinization during the procedure and therapy ...

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

Cooled Radiofrequency Catheter Ablation

2001
During the past decade, radiofrequency catheter ablation has emerged as an important definitive approach to the treatment of most types of ventricular and supraventricular arrhythmias.1,2 The development of temperature monitoring and closed loop temperature control of RF energy output was subsequently shown to facilitate RF catheter ablation and have ...

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 ...

Delayed Success Following Radiofrequency Catheter Ablation

Pacing and Clinical Electrophysiology, 1993
Two patients who underwent attempted radiofrequency catheter ablation of an atrioventhcular accessory pathway experienced delayed abolition of pathway conduction. During the procedures there was transient block in the accessory pathway following multiple ablotion attempts at closely spaced sites.

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 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
