Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

Statistical Atlases for Electroanatomical Mapping of Cardiac Arrhythmias

, 2017
Electroanatomical mapping is a mandatory time-consuming planning step in cardiac catheter ablation. In practice, interventional cardiologists target specific endocardial areas for mapping based on personal experience, general electrophysiology principles, and preoperative anatomical scans.

In silico predictions of action potential propagation in doxorubicin cardiotoxicity: A parametric study using preclinical 3D magnetic resonance imaging‐based fibrotic left ventricle models

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the study's methodology and key findings. In a preclinical swine model, doxorubicin administration induced cardiotoxicity, characterized by diffuse fibrotic remodelling and altered electrical function, as assessed by magnetic resonance (MR) imaging and electrophysiological mapping.

Functional Activation Mapping of Scar-Related Ventricular Tachycardia Substrate

Journal of Cardiac Arrhythmias, 2020
The optimal method to identify the arrhythmogenic substrate of scar-related ventricular tachycardia (VT) is unknown. Sites of activation slowing during sinus rhythm (SR) often co-localize with the VT circuit.

Electroanatomical Mapping-Guided Low Fluoroscopy Left Bundle Branch Pacing

JACC: Clinical Electrophysiology, 2020
A 70-year-old man with complete heart block, recurrent syncope, and normal left ventricular function was referred for pacemaker implantation. An option to perform left bundle branch pacing (LBBP) ([1][1]) using electroanatomic mapping guidance was discussed with the patient and informed consent ...
