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

The 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.

Deep Learning‐Based Dynamic Segmentation of the Left Atrium in 4D Flow MRI

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2505-2515, November 2026.
ABSTRACT Purpose To design a deep learning pipeline for automated, time‐resolved segmentation of the left atrium (LA) from 4D flow MRI data. Methods We studied 100 individuals including 65 patients with atrial fibrillation (AF) and 35 healthy subjects (HS) resulting in 2530 4D flow MRI time‐volumes acquired in different centers and scanners.

Supravalvular congenital mitral stenosis

, 2017
Congenital supravalvular mitral stenosis is a rare malformation characterized by the presence of a shelf-like fibrous membrane, with 1 or 2 small orifices, covering and obstructing the mitral valve. The membrane is positioned closely to the mitral valve (

Balloon valvuloplasty for mild mitral stenosis

, 1991
Of a total number of 288 patients with mitral stenosis treated by percutaneous balloon valvuloplasty, 21 patients had a basal mitral area equal to or greater than 1.5 cm2, as measured hemodynamically.

Mitral regurgitation and decompensated heart failure in a young pregnant pony mare: An aetiological challenge

Equine Veterinary Education, Volume 38, Issue 10, Page e676-e685, October 2026.
Summary A 4‐year‐old, 6‐month pregnant, Welsh pony mare presented with severe acute clinical signs including depression, anorexia, pale mucous membranes, tachycardia with a grade 4/6 holosystolic murmur and moderate expiratory dyspnoea with diffuse wheezes. There was no evidence of placentitis or fetal distress.

Nucleic Acids as Emerging Regulators of Calcium Phosphate Biomineralization

The FASEB Journal, Volume 40, Issue 17, 15 September 2026.
Calcium phosphate biomineralization has traditionally been considered a protein‐regulated process. This review highlights the emerging role of nucleic acids, which interact with mineral phases through adsorption, coprecipitation, and templating, thereby influencing crystal nucleation and growth.

Identification of major congenital malformations based on healthcare databases in France: A proof‐of‐concept study using the epi‐meres nationwide mother–child register

British Journal of Clinical Pharmacology, Volume 92, Issue 9, Page 3037-3048, September 2026.
Abstract Aim Besides registries, healthcare databases can provide useful information for assessing the frequency of major congenital malformations (MCMs) and investigating their risk factors, particularly medication exposures. This study aimed to assess the validity of MCMs identification based on French national, comprehensive healthcare databases ...

Phonocardiographic study in patients with mitral stenosis

, 1971
의학과/석사[한글] [영문] In 1911 Weiss and Joachim reported a delay in the onset of the first heart sound in mitral stenosis, and in 1951 Sprague and his associates demonstrated that in patients with mitral stenosis and atrial fibrillation the Q-1 interval ...
