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.

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.

Catheter contact area strongly correlates with lesion area in radiofrequency cardiac ablation: an ex vivo porcine heart study

Journal of interventional cardiac electrophysiology, 2021
Our previous study confirmed that not only force but also the catheter contact angle substantially impacted the contact area and its morphology. Therefore, in this study, we aimed to further investigate the relationship between the catheter contact area ...

Atrial fibrillation progression after cryoablation versus radiofrequency ablation: the CIRCA-DOSE trial.

European Heart Journal, 2023
BACKGROUND AND AIMS Atrial fibrillation (AF) is a chronic, progressive disorder. Persistent forms of AF are associated with increased rates of thromboembolism, heart failure, and death.

Radiofrequency Catheter Ablation of Parahisian Accessory Pathway

Journal of Interdisciplinary Medicine, 2016
Radiofrequency catheter ablation of parahisian accessory pathways in pre-excitation syndrome is a challenging task, due to the extremely high risk of complete atrioventricular block.

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.

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 ...

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.

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

Successful Radiofrequency Catheter Ablation of The Para-Hisian Accessory Pathway in A Patient with Wolf Parkinson White Syndrome

Majalah Kardiologi Indonesia, 2013
Radiofrequency catheter ablation of the accessory pathway in Wolff-Parkinson-White (WPW) syndrome is a highly successful mode of therapy. Sudden cardiac arrest survivors associated with WPW syndrome should undergo radiofrequency catheter ablation.
