Navigating the Zero Fluoroscopy Frontier: Current Tools, Evidence and Future Directions in Electrophysiology Procedures

Pacing and Clinical Electrophysiology, EarlyView.
Graphical Abstract ABSTRACT Fluoroscopy has traditionally been the mainstay imaging technique for guidance during electrophysiology (EP) ablation procedures. The numerous disadvantages associated with radiation exposure for both operators and patients have created the need for zero‐fluoroscopy (ZF) approaches. Today, electrophysiologists have access to

Comparative multimodal calibration of patient‐specific atrial fibrillation models: Impact of imaging and electrophysiology data on arrhythmogenic substrate identification

The Journal of Physiology, EarlyView.
Abstract figure legend Comparative multimodal calibration of patient‐specific left atrial (LA) models to identify arrhythmogenic substrates in atrial fibrillation (AF). A, LA models shown in posterior and anterior views, calibrated separately using: late gadolinium enhancement magnetic resonance imaging (LGE‐MRI) image intensity ratio (IIR; blue–red ...

Interatrial block is an independent risk factor for new-onset atrial fibrillation after cardiac surgeryCentral MessagePerspective

JTCVS Open
Objectives: This study aims to investigate the association between interatrial conduction block and postoperative atrial fibrillation, which can precipitate acute cardiopulmonary instability and is associated with subsequent heart failure, stroke, and ...

Interatrial block in prediction of all-cause mortality after first-ever ischemic stroke

BMC Cardiovascular Disorders, 2019
Background Interatrial block (IAB) is an ECG indicator of atrial fibrosis related to atrial remodeling and thrombus formation thus leading to embolic stroke and increasing mortality.

Channelrhodopsin ion selectivity determines mechanisms and efficacy of optogenetic defibrillation in human atria and ventricles

The Journal of Physiology, EarlyView.
Abstract figure legend A, we used in silico models of human cardiomyocytes and microelectrode recordings on transgenic zebrafish hearts to study electrophysiology during optogenetic perturbations. Specifically, we compared effects of three distinct classes of channelrhodopsins: the cation non‐selective Chlamydomonas reinhardtii channelrhodopsin‐2 (ChR2)

Interatrial block as electrocardiographic predictive sign for atrial fibrillation in Internal Medicine Departments hospitalized patients

Italian Journal of Medicine, 2019
This study evaluated the correlation between interatrial block (IAB) and atrial fibrillation (AF) among patients admitted to our Internal Medicine Unit: 110 (group 1) were identified with electrocardiograms both in sinus rhythm and AF, and 123 (group 2 ...

A Large Retrospective Study to Evaluate Utility of Zephyr Covered Stent in Transcatheter Closure of Sinus Venosus Defects

Catheterization and Cardiovascular Interventions, Volume 108, Issue 5, Page 1808-1817, November 1, 2026.
ABSTRACT Background Transcatheter closure (TCC) of sinus venosus defects (SVD) using balloon‐expandable covered stents is an emerging alternative to surgery. ZephyrCS (Sahajanand Laser Technologies, Gandhinagar, India) is available in long lengths to suit SVD closure.

Association of P‐Wave Parameters With Left Atrial Hemodynamics in Atrial Cardiomyopathy

Annals of Noninvasive Electrocardiology
Background P‐wave parameters, readily obtainable from standard 12‐lead ECGs, have been associated with atrial fibrillation (AF), ischemic stroke, and other cardiovascular conditions. Left atrial cardiomyopathy (AtCM), characterized by atrial fibrosis and

Right Ventricular Dysfunction and Ventriculo‐Arterial Uncoupling in Heart Failure With Preserved Ejection Fraction: A Phenotype‐Specific Review of Mechanisms, Diagnosis, and Therapeutic Strategies

Clinical Cardiology, Volume 49, Issue 11, November 2026.
Right ventricular dysfunction affects 19%–33% of patients With heart failure With preserved ejection fraction and is associated With exercise intolerance, hospitalization, and mortality. Assessing right ventricular function and its coupling with the pulmonary circulation may improve risk stratification and support management tailored to distinct ...
