Laser ablation production of Ba, Ca, Dy, Er, La, Lu, and Yb ions [PDF]

Appl. Phys. B 123, 99 (2017), 2016
We use a pulsed nitrogen laser to produce atomic ions by laser ablation, measuring the relative ion yield for several elements, including some that have only recently been proposed for use in cold trapped ion experiments. For barium, we monitor the ion yield as a function of the number of applied ablation pulses for different substrates.

An abnormal left ventricular-atrial perforation after radiofrequency catheter ablation: a case report

Journal of Cardiothoracic Surgery, 2019
Background Cardiac radiofrequency ablation is a popular treatment for arrhythmias. However, it does have some complications, some of which are severe, even fatally.

Angiotensin receptor-neprilysin inhibitor therapy and recurrence of atrial fibrillation after radiofrequency catheter ablation: A propensity-matched cohort study

Frontiers in Cardiovascular Medicine, 2022
BackgroundCompared with conventional medicines, angiotensin receptor-neprilysin inhibitor (ARNI) could further improve the prognosis for multiple cardiovascular diseases, such as heart failure, hypertension, and myocardial infarction.

Effect of energy dissipation on radiofrequency ablation model in cardiac tissue: modelling, analysis and numerical simulation [PDF]

arXiv, 2023
This paper deals with the mathematical analysis and numerical simulation of a new nonlinear ablation system modeling radiofrequency ablation phenomena in cardiac tissue, {which incorporates the effects of blood flow on the heat generated when ablation by radiofrequency. The model also considers the effects of viscous energy dissipation.

Results of Cryoenergy and Radiofrequency-Based Catheter Ablation for Treating Ventricular Arrhythmias Arising From the Papillary Muscles of the Left Ventricle, Guided by Intracardiac Echocardiography and Image Integration

Circulation: Arrhythmia and Electrophysiology, 2016
Background—Catheter radiofrequency ablation of ventricular arrhythmias (VAs) arising from the left ventricle’s papillary muscles has been associated with inconsistent results. The use of cryoenergy versus radiofrequency has not been compared yet.

Association between functional mitral regurgitation and recurrence of paroxysmal atrial fibrillation following catheter ablation: a prospective cohort study

Journal of International Medical Research, 2021
Objective The present study aimed to investigate the effect of functional mitral regurgitation (FMR) on recurrence of paroxysmal atrial fibrillation (PAF) in patients undergoing radiofrequency catheter ablation.

Near-Field Ultrasound Imaging During Radiofrequency Catheter Ablation: Tissue Thickness and Epicardial Wall Visualization and Assessment of Radiofrequency Ablation Lesion Formation and Depth

Circulation: Arrhythmia and Electrophysiology, 2017
Background Safe and successful radiofrequency catheter ablation depends on creation of transmural lesions without collateral injury to contiguous structures.

Bilateral pulmonary vein stenting for treatment of massive hemoptysis caused by pulmonary vein stenosis following catheter ablation for atrial fibrillation

BMC Cardiovascular Disorders, 2019
Background Massive hemoptysis is a life-threatening condition. Massive hemoptysis caused by pulmonary vein stenosis (PVS) after radiofrequency catheter ablation for atrial fibrillation (AF) is rare.

Radiofrequency catheter ablation in infants and children

SA Heart, 2017
Background: Diagnosis and treatment of paediatric arrhythmias remain challenging. Antiarrhythmic - drugs beta-blockers, class Ic and class III drugs, were the only treatment available for many years. Radiofrequency catheter ablation (RFCA) was introduced for adult patients in 1981 and has been used for children since 1989.

Epicardial Ablation of Ventricular Tachycardia with Manual Controlled External Irrigation in a Patient with Nonischemic Cardiomyopathy

Journal of Arrhythmia, 2009
We describe a patient with nonischemic cardiomyopathy who underwent radiofrequency (RF) catheter ablation for a drug-refractory ventricular tachycardia (VT). RF ablation from a left ventricular (LV) endocardial site failed to eliminate the VT.
