Thoracoscopic surgical ablation versus catheter ablation as first-line treatment for long-standing persistent atrial fibrillation: the CASA-AF RCT

Efficacy and Mechanism Evaluation, 2021
Background: Standalone thoracoscopic surgical ablation may be more effective than catheter ablation in patients with long-standing persistent atrial fibrillation.

Catheter ablation of right ventricular outflow tract tachycardia using contact force guidance [PDF]

, 2014
Outflow tract tachycardias (OTT) originating from the right or left ventricular outflow tract are thought to be benign. However, symptoms can be disabling and deterioration of left ventricular function may occur with a high arrhythmia burden.

Design and Evaluation of a Catheter Contact-Force Controller for Cardiac Ablation Therapy. [PDF]

, 2016
GOAL: Maintaining a constant contact force (CF) of an ablation catheter during cardiac catheter ablation therapy is clinically challenging due to inherent myocardial motion, often resulting in poor ablation of arrhythmogenic substrates.

MR-conditional Robotic Actuation of Concentric Tendon-Driven Cardiac Catheters [PDF]

arXiv, 2023
Atrial fibrillation (AF) and ventricular tachycardia (VT) are two of the sustained arrhythmias that significantly affect the quality of life of patients. Treatment of AF and VT often requires radiofrequency ablation of heart tissues using an ablation catheter.

Efficacy of High Temporal Frequency Photoacoustic Guidance of Laser Ablation Procedures [PDF]

, 2021
Inaccurate placement of the ablation catheter and the inability to monitor the real-time temperature within the tissue of interest such as veins curbs the treatment efficacy of laser ablation procedures during thermal therapies. Our previous studies have

Neural Network Reconstruction of the Left Atrium using Sparse Catheter Paths [PDF]

arXiv, 2023
Catheter based radiofrequency ablation for pulmonary vein isolation has become the first line of treatment for atrial fibrillation in recent years. This requires a rather accurate map of the left atrial sub-endocardial surface including the ostia of the pulmonary veins, which requires dense sampling of the surface and takes more than 10 minutes.
