Detection of the origin of atrial tachycardia by 3D electro‐anatomical mapping and treatment by radiofrequency catheter ablation in horses

Journal of Veterinary Internal Medicine, 2022
Background Atrial tachycardia (AT) can be treated by medical or electrical cardioversion but the recurrence rate is high. Three‐dimensional electro‐anatomical mapping, recently described in horses, might be used to map AT to identify a focal source or ...

Simplified method for esophagus protection during radiofrequency catheter ablation of atrial fibrillation - prospective study of 704 cases

Brazilian Journal of Cardiovascular Surgery, 2015
Introduction:Although rare, the atrioesophageal fistula is one of the most feared complications in radiofrequency catheter ablation of atrial fibrillation due to the high risk of mortality.Objective:This is a prospective controlled study, performed ...

Effect of Isthmus Anatomy and Ablation Catheter on Radiofrequency Catheter Ablation of the Cavotricuspid Isthmus [PDF]

Circulation, 2004
Background— Cavotricuspid isthmus (CTI) characteristics are rarely documented when comparing catheters in radiofrequency ablation (RFA) of atrial flutter (AFL). Our objectives were (1) to evaluate the impact of CTI morphology and length on ablation procedures and (2) to compare the efficacy of an 8 ...

A Focal Ablation Catheter Toggling Between Radiofrequency and Pulsed Field Energy to Treat Atrial Fibrillation.

JACC Clinical Electrophysiology, 2023
BACKGROUND Because of its safety, "single-shot" pulsed field ablation (PFA) catheters have been developed for pulmonary vein isolation (PVI). However, most atrial fibrillation (AF) ablation procedures are performed with focal catheters to permit ...

Cryoablation to improve catheter stability and ablation success in the right atrioventricular groove

Indian Pacing and Electrophysiology Journal, 2021
Catheter instability can limit ablation success of arrhythmia substrates at the right atrioventricular groove. We describe cases where cryoablation improved catheter stability, enabling ablation success.

Radiofrequency Versus Cryoballoon Catheter Ablation for Paroxysmal Atrial Fibrillation: Durability of Pulmonary Vein Isolation and Effect on Atrial Fibrillation Burden

Circulation: Arrhythmia and Electrophysiology, 2021
Supplemental Digital Content is available in the text. Background: Recurrent paroxysmal atrial fibrillation (AF) after catheter ablation is presumably caused by failure to achieve durable pulmonary vein isolation (PVI).

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.

Atrial fibrillation gut syndrome: severe gastroparesis with pyloric spasm following radiofrequency catheter ablation of drug resistant symptomatic atrial fibrillation: a case report

Journal of Medical Case Reports, 2023
Background Atrial fibrillation is the most common cardiac arrhythmia, and cardiac ablation is one of the treatment modalities for persistent symptomatic atrial fibrillation.

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.
