Catheter Ablation of Idiopathic Ventricular Arrhythmias Originating from the Para-Hisian area - QRS Morphology Change and Late Effect of the Ablation: Case Series [PDF]

Folia Medica, 2020
Introduction: Radiofrequency catheter ablation of idiopathic ventricular arrhythmias originating in the para-Hisian region could be challenging because of a potential risk of iatrogenic atrioventricular block.

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 ablation using radiofrequency energy [PDF]

Clinical Cardiology, 1990
AbstractRecently, transvenous catheter ablation using radiofrequency impulses has been applied in experimental animals as well as in humans. This review describes the biophysics, mechanisms, and tissue effects of radio‐frequency alternating current. Ablation of the AV‐junction has been performed in experimental studies as well as in a growing number of

A worldwide survey on incidence, management, and prognosis of oesophageal fistula formation following atrial fibrillation catheter ablation: the POTTER-AF study

European Heart Journal, 2023
Aims Oesophageal fistula represents a rare but dreadful complication of atrial fibrillation catheter ablation. Data on its incidence, management, and outcome are sparse.

Mitral valve perforation after left lateral accessory pathway ablation: a case report

Journal of Cardiothoracic Surgery, 2022
Background Radiofrequency catheter ablation is considered to be a relatively safe procedure. This is an unusual case report in which severe mitral regurgitation was occurred after left lateral accessory pathway radiofrequency catheter ablation.

A computational model of open‐irrigated radiofrequency catheter ablation accounting for mechanical properties of the cardiac tissue [PDF]

International Journal for Numerical Methods in Biomedical Engineering, 2018
Radiofrequency catheter ablation (RFCA) is an effective treatment for cardiac arrhythmias. Although generally safe, it is not completely exempt from the risk of complications.

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 ...
