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

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.

Bipolar Radiofrequency Catheter Ablation for Ventricular Arrhythmias

Reviews in Cardiovascular Medicine, 2022
A minority of premature ventricular contractions (PVC) and ventricular tachycardias (VT) have an intramural origin, which represents a challenge for conventional radiofrequency ablation. Bipolar ablation has the potential ability to create deeper and more transmural lesions and has been demonstrated to be optimal treatment in these cases.

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.

Case Report: Application of Thoracoscopic Clamp Radiofrequency Ablation on Atrial Tachycardia Originating From Right Atrial Appendage After Catheter Ablation Failure

Frontiers in Cardiovascular Medicine, 2021
Atrial tachycardia originating from the right atrial appendage has a higher probability of failure of catheter ablation. Here we report a case of a 13-year-old boy with incessant tachycardia, complicated by heart enlargement, and heart failure ...
