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 ...

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 ...

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.

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

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 ...

Neonatal Radiofrequency Catheter Ablation of Junctional Tachycardias

Journal of Interventional Cardiac Electrophysiology, 1997
Junctional tachycardias comprise several arrhythmia types with differing mechanisms, principally involving the region of the atrioventricular (A-V) junction. Neonatal radiofrequency catheter ablation has typically been reserved for life-threatening, drug-refractory cases due to the unique concerns regarding patient size and development.

Soft Thrombus Formation in Radiofrequency Catheter Ablation

Pacing and Clinical Electrophysiology, 2002
DEMOLIN, J.M., et al.: Soft Thrombus Formation in Radiofrequency Catheter Ablation. During RF catheter ablation, local temperature elevation can result in coagulum formation on the ablation electrode, resulting in impedance rise. A recent study has also demonstrated the formation of a so‐called soft thrombus during experimental ablations. This deposit

Efficacy and safety of radiofrequency catheter ablation in the elderly

Journal of Interventional Cardiac Electrophysiology, 2007
Radiofrequency (RF) catheter ablation has not been widely undertaken in elderly patients. The aim of our study was to compare the success rate of radiofrequency ablation and the incidence of severe procedural complications in young-adult and elderly patients.We enrolled all patients undergoing radiofrequency catheter ablation procedures for ...

Advanced radiofrequency catheter ablation in canine myocardium

American Heart Journal, 1994
Current radiofrequency (RF) ablation technology is limited by small lesion size. To enhance the size of RF-induced left ventricular (LV) endocardial lesions, we evaluated the effects of an enlarged distal electrode tip and increased RF power on lesion volume.
