Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Dyssynchrony without dysfunction: Left bundle branch block does not acutely reduce cardiac output

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Six electromechanical in silico heart models were simulated under healthy and pure acute left bundle branch block (LBBB) conditions. LBBB induced electrical dyssynchrony and increased left ventricular free wall strain, while the right and left ventricular ejection fraction remained relatively unchanged.

Transthoracic three-dimensional echocardiography for the assessment of straddling tricuspid or mitral valves [PDF]

open access: yes, 2000
Background The advent of 3D echocardiography has provided a technique which, potentially, could afford significant additional information over conventional cross-sectional echocardiography in the assessment of patients with straddling atrioventricular ...

Benchmarking commercial large language models for gene–disease–phenotype extraction from full‐text human genetics literature

open access: yesQuantitative Biology, Volume 14, Issue 4, December 2026.
Abstract Manual curation of gene–disease–phenotype relationships from the human genetics literature is a persistent bottleneck for maintaining its bioinformatics databases. Whereas large language models (LLMs) offer a promising alternative, there is currently no systematic benchmark that evaluates whether state‐of‐the‐art commercial LLMs can perform ...

Diastolic Function in Paced Children with Cardiac Defects: Septum vs Apex

open access: yesArquivos Brasileiros de Cardiologia, 2015
In children with structural congenital heart disease (CHD), the effects of chronic ventricular pacing on diastolic function are not well known. On the other hand, the beneficial effect of septal pacing over apical pacing is still controversial.The aim of

Evaluation of a novel fetal echocardiography training programme in two tertiary care obstetric Centres

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 175, Issue 2, Page 771-778, November 2026.
Abstract Objectives Improving and maintaining high detection rates for major congenital heart disease (CHD) is a priority for successful prenatal anatomy screening programmes. The primary objective of this study was to evaluate the utility of on‐site multidimensional targeted training in fetal cardiac screening. Methods A prospective study evaluating a

The clinical, electrocardiographic and echocardiographic features and long-term outcome of patients with Tachycardia-induced cardiomyopathy [PDF]

open access: yes, 2010
Includes abstract.Includes bibliographical references.Tachycardia-induced cardiomyopathy (TIC) is a reversible cause of LV systolic dysfunction that can complicate any supraventricular or ventricular tachyarrhythmia.

Left bundle branch pacing in third-degree atrioventricular block following morrow surgery: a case report

open access: yesFrontiers in Cardiovascular Medicine
Left bundle branch pacing (LBBP) has proven to be an alternative method for delivering physiological pacing to achieve electrical synchrony of the left ventricle (LV), especially in patients with atrioventricular block and left bundle branch block (LBBB).

Electrocardiographic and Skin Manifestations of Turner Syndrome: Association With Cardiovascular Disease

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 10, Page 2234-2240, October 2026.
ABSTRACT Congenital heart disease (CHD) and dermatologic conditions such as lymphedema and acquired melanocytic nevi (AMN) are common in Turner Syndrome (TS). We hypothesized that abnormalities of cranial neural crest cell derivatives drive the skin and heart manifestations of TS. We conducted joint cardiac and skin examinations of volunteers at a 2023

Validation of an Automated Artificial Intelligence‐Driven Planner for Transcatheter Aortic Valve Replacement

open access: yesCatheterization and Cardiovascular Interventions, Volume 108, Issue 4, Page 1473-1481, October 1, 2026.
ABSTRACT Background Preprocedural planning with multislice computed tomography (MSCT) is an essential prerequisite for successful transcatheter aortic valve replacement (TAVR). However, preprocedural planning is time‐consuming and may contain clinically meaningful interobserver variability.
