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.

Catheter Ablation of Canine Myocardium with Radiofrequency Energy

Pacing and Clinical Electrophysiology, 1989
High energy direct‐current shocks delivered via an electrode catheter have been used to ablate the atrioventricular junction since 1981.1 This technique has also been adapted for ablation of other cardiac tissues including the atrium, posterior interatrial septum and ventricular myocardium.

Radiofrequency Catheter Ablation of Refractory Ventricular Tachycardia

Pacing and Clinical Electrophysiology, 1988
Transcatheter radiofrequency ablation of the arrhythmia focus was attempted in a 68‐year‐old patient with recurrent ventricular tachycardia, both spontaneous and inducible by programmed ventricular stimulation despite treatment with multiple antiarrhythmic drugs. The procedure was performed under local anesthetic without complication.

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

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 in symptomatic ventricular arrhythmia

Australian and New Zealand Journal of Medicine, 1997
Abstract Background: Radiofrequency catheter ablation (RFCA) is an effective method to cure both supraventricular and ventricular arrhythmia (VA) in certain centres. Aim: To assess the results of RFCA in VA at Siriraj Hospital. Method: Electrophysiologic study, mapping, using both earliest endocardial activation and pace mapping, and ablation were ...

Radiofrequency Catheter Ablation of Cardiac Arrhythmias

Volume 2: Biomedical and Biotechnology Engineering; Nanoengineering for Medicine and Biology, 2011
Radiofrequency ablation could be described as a thermal strategy to destroy a tissue by increasing its temperature and causing anirreversible cellular injury. Radiofrequency ablation is a relatively new modality which has found use in a wide range of medical applications and gained acceptance.
