Position‐dependent offset corrections for ring applicator reconstruction in cervical cancer brachytherapy

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
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.

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

open access: yesJournal 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.

Patient characteristics, procedure details including catheter devices, and complications of catheter ablation for ventricular tachycardia: a nationwide observational study

open access: yesJournal of Arrhythmia, 2020
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.

open access: yesNew England Journal of Medicine, 2015
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 ...

Open‐source deep‐learning models for segmentation of normal structures for prostatic and gynecological high‐dose‐rate brachytherapy: Comparison of architectures

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
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]

open access: yesMedical Image Computing and Computer Assisted Intervention (MICCAI) 2018. Lecture Notes in Computer Science, vol 11071. Springer, Cham, 2018
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

open access: yesJournal of Thoracic Disease, 2019
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.

Implementation of needle‐tracking technology for real‐time transrectal ultrasound‐guided interstitial gynecological HDR brachytherapy: A feasibility study

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
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.

Effect of Catheter Ablation vs Antiarrhythmic Medication on Quality of Life in Patients With Atrial Fibrillation: The CAPTAF Randomized Clinical Trial

open access: yesJournal of the American Medical Association (JAMA), 2019
Importance Quality of life is not a standard primary outcome in ablation trials, even though symptoms drive the indication. Objective To assess quality of life with catheter ablation vs antiarrhythmic medication at 12 months in patients with atrial ...

Catheter ablation of atrial fibrillation: an update [PDF]

open access: yes, 2017
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 ...
