Catheter entrapment in Chiari network: Extraction with radiofrequency

Indian Pacing and Electrophysiology Journal, 2019
We report a challenging case of a duodecapolar mapping catheter entrapment in Chiari network and its release by radiofrequency energy application with an ablation catheter.

Ultrasonic characterization of the pulmonary venous wall: echographic and histological correlation [PDF]

, 2002
Background: Pulmonary vein isolation with radiofrequency catheter ablation techniques is used to prevent recurrences of human atrial fibrillation. Visualization of the architecture at the venoatrial junction could be crucial for these ablative techniques.

Radiofrequency Catheter Ablation for Ventricular Tachycardia [PDF]

Heart, Lung and Circulation, 2012
The management of ventricular tachycardia (VT) has evolved considerably in recent times. The majority of patients with VT have structural heart disease and often implantable defibrillators. Implantable defibrillators can terminate ventricular arrhythmias and prevent sudden death but do not prevent these arrhythmias from occurring.

Technical advance in silico and in vitro development of a new bipolar radiofrequency ablation device for renal denervation

BMC Cardiovascular Disorders, 2021
Background Renal denervation with radiofrequency ablation has become an accepted treatment for drug-resistant hypertension. However, there is a continuing need to develop new catheters for high-accuracy, targeted ablation.

Transient complete heart block following catheter ablation of a left lateral accessory pathway. [PDF]

, 2019
A 16-year-old female with symptomatic Wolff-Parkinson-White (WPW) syndrome underwent catheter ablation of a left-sided lateral accessory pathway. The accessory pathway was eliminated with the first ablation lesion; however, the patient immediately ...

Anatomical characteristics of pulmonary veins for the prediction of postoperative recurrence after radiofrequency catheter ablation of atrial fibrillation.

PLoS ONE, 2014
BackgroundThe relationship between focal pulmonary vein potential and atrial fibrillation (AF) has been confirmed. Pulmonary vein (PV) isolation and circumferential pulmonary vein ablation have been the most commonly used procedures of radiofrequency ...

Randomized trial of conventional transseptal needle versus radiofrequency energy needle puncture for left atrial access (the TRAVERSE-LA study). [PDF]

, 2013
BackgroundTransseptal puncture is a critical step in achieving left atrial (LA) access for a variety of cardiac procedures. Although the mechanical Brockenbrough needle has historically been used for this procedure, a needle employing radiofrequency (RF)

Matrix metalloproteinase-9 as an independent predictor of recurrence after catheter ablation of atrial fibrillation

Journal of Education, Health and Sport, 2017
Objectives: In this study, the serum level of matrix metalloproteinase-9 was studied as an independent predictor of recurrence after catheter ablation of a persistent form of atrial fibrillation. Methods: The study included 46 patients with a persistent
