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.

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.

Radiofrequency Catheter Ablation of Accessory Pathways:

Journal of Cardiovascular Electrophysiology, 1994
RF Catheter Ablation of APs. Catheter ablation techniques are now advocated as the first line of therapy for arrhythmias caused by accessory pathways (APs). The most common energy source is radiofrequency current, but technical characteristics vary. Several parameters can be used to determine the optimal target site: AP potential, AV time, atrial or ...

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.

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.

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.

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 ...
