Left Atrial Scar Formation After Contact Force‐Guided AF Ablation Background Catheter
contact force (CF) is an important determinant of radiofrequency (RF) lesion quality during …

Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice today.
Until recently, the therapeutic approaches for AF have been limited by imperfect risk …

Purpose A new real‐time MR‐thermometry pipeline was developed to measure multiple
temperature images per heartbeat with 1.6× 1.6× 3 mm3 spatial resolution. The method was …

Since the emergence of atrial fibrillation (AF) ablation as a reliable method of restoring sinus
rhythm, various approaches have been used to improve the efficacy while maximizing the …

Objective: Design and optimization of statistical models for use in methods for estimating
radiofrequency ablation (RFA) lesion depths in soft real-time performance. Methods: Using …

Purpose To develop and demonstrate in vitro and in vivo a single interventional magnetic

Introduction Interventional cardiac MRI in the context of the treatment of cardiac arrhythmia
requires submillimeter image resolution to precisely characterize the cardiac substrate and …

Thin-film micro-coils are integrated with commercially available ablation catheters, for MR-
thermometry during laser interstitial thermal therapies (LITTs). The coils are formed on a …

Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice.
Catheter ablation is now a recognized treatment for those with symptomatic AF refractory to …
