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 ...

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.

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.

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

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.

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 ...

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

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 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.

Results of radiofrequency catheter ablation for atrial flutter

The American Journal of Cardiology, 1996
RF catheter ablation for symptomatic typical atrial flutter is associated with a high procedural success rate, but a second RF procedure may be required in up to one third of subjects, particularly those with right atrial enlargement. In those subjects with both established AF and flutter, RF ablation for atrial flutter may decrease the recurrence rate
