Abstract Purpose Due to the tight curvature in their design, ring applicators are usually associated with large positioning errors. The standard practice to correct for these deviations based on global offsets may not be sufficient to comply with the recommended tolerance.

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.

Background Nationwide data are insufficient with respect to the characteristics of patients undergoing ventricular tachycardia (VT) ablation, complications of VT ablation, and procedure details including catheter devices used during VT ablation.

Approaches to catheter ablation for persistent atrial fibrillation.
BACKGROUND Catheter ablation is less successful for persistent atrial fibrillation than for paroxysmal atrial fibrillation. Guidelines suggest that adjuvant substrate modification in addition to pulmonary-vein isolation is required in persistent atrial ...

Abstract Background The use of deep learning‐based auto‐contouring algorithms in various treatment planning services is increasingly common. There is a notable deficit of commercially or publicly available models trained on large or diverse datasets containing high‐dose‐rate (HDR) brachytherapy treatment scans, leading to poor performance on images ...

More Knowledge is Better: Cross-Modality Volume Completion and 3D+2D Segmentation for Intracardiac Echocardiography Contouring [PDF]
Using catheter ablation to treat atrial fibrillation increasingly relies on intracardiac echocardiography (ICE) for an anatomical delineation of the left atrium and the pulmonary veins that enter the atrium. However, it is a challenge to build an automatic contouring algorithm because ICE is noisy and provides only a limited 2D view of the 3D anatomy ...

Catheter ablation: an ongoing revolution
The field of interventional electrophysiology has progressed significantly over the last decades as the techniques and technologies have become increasingly complex. Catheter ablation has been established as an effective, durable, and safe method to manage arrhythmias.

Abstract Purpose To investigate the feasibility of adapting a commercial prostate biopsy system for transrectal ultrasound (TRUS)‐guided hybrid gynecological (GYN) high‐dose‐rate (HDR) brachytherapy (BT). Leveraging 3D‐TRUS and MR image fusion, the prototype system aims to improve real‐time needle placement accuracy.

Catheter ablation of atrial fibrillation: an update [PDF]
Catheter ablation of atrial fibrillation (AF) is now an important therapeutic modality for patients with AF. There is considerable evidence available from several prospective randomized trials demonstrating that catheter ablation of AF is superior to ...
