Catheter ablation for atrial fibrillation (AF) has emerged as an important rhythm-control
strategy and is by far the most common cardiac ablation procedure performed worldwide …

Background: Radiofrequency ablation using irrigated catheters is performed using a power-
controlled mode. However, lesion size is dependent on current delivery at a particular …

Cardiac optical mapping, also known as optocardiography, employs parameter-sensitive
fluorescence dye (s) to image cardiac tissue and resolve the electrical and calcium …

Purpose To evaluate non‐contrast‐enhanced MRI of acute radio‐frequency ablation (RFA)
lesions in the left atrium (LA) and pulmonary vein (PV) ostia. The goal is to provide a method …

Background Currently, there are limited means for high-resolution monitoring of tissue injury
during radiofrequency ablation procedures. Objective To develop the next generation of …

Background Safe and successful radiofrequency catheter ablation depends on creation of
transmural lesions without collateral injury to contiguous structures. Near-field ultrasound …

Background Treatment of cardiac arrhythmias often involves ablating viable muscle tissue
within or near islands of scarred myocardium. Yet, today there are limited means by which …

Despite considerable advances in guidance of radiofrequency ablation (RFA) therapy for the
treatment of cardiac arrhythmias, success rates have been hampered by a lack of tools for …

Radiofrequency ablation is a commonly used clinical procedure that destroys
arrhythmogenic sources in patients suffering from atrial fibrillation and other types of cardiac …

From the time of early preclinical reports of the efficacy, speed and safety of pulsed field
ablation (PFA), the interventional electrophysiology community has been waiting in anxious …
