Structural determinants of re‐entrant drivers in atrial fibrillation: insights from digital twins derived from 3D micrometre‐resolution imaging of human heart

The Journal of Physiology, Volume 604, Issue 13, Page 5610-5628, 1 July 2026.
Abstract figure legend Digital heart models of human donor atria with cardiac co‐morbidities revealed that regions with AWT variation, aligned myofibres adjacent to disorganised zones and fibrotic borders promoted the localisation and stability of RDs. AWT had a global influence, whereas fibre orientation and fibrosis exerted chamber‐specific regional ...

Unveiling sex dimorphism in the healthy cardiac anatomy: Fundamental differences between male and female heart shapes

The Journal of Physiology, Volume 604, Issue 13, Page 5512-5534, 1 July 2026.
Abstract figure legend We present a shape modelling‐based morphological analysis of sex differences in cardiac anatomy. We conduct our analysis on 456 healthy subjects from the UK Biobank (227M/229F) to uncover sex‐based differences in healthy cardiac morphology.

Heterotopic Transcatheter Tricuspid Valve Replacement in Severe Tricuspid Regurgitation and Refractory Right Heart Failure

, 2022
Torrential tricuspid regurgitation may lead to heart failure and poor survival and quality of life. Heterotopic transcatheter tricuspid replacement is increasingly offered to patients unsuitable for direct valve repair or replacement.

Locomotor muscle dysfunction and rehabilitative exercise training in fibrotic interstitial lung disease: Where are we at and where could we go?

Experimental Physiology, Volume 111, Issue 6, Page 2860-2879, 1 June 2026.
Abstract Exercise limitation is a cardinal feature of fibrotic interstitial lung disease arising from pulmonary gas exchange, respiratory mechanical and cardio‐circulatory abnormalities. More recently, it has been recognized that impairment in locomotor muscle function (e.g., reduced muscle mass/strength or heightened fatigability) might also play a ...

Age-Related Histological Changes in Vena Caval System of Human Foetus and Adult: A Comparative Study

, 2020
BACKGROUND: It has been documented that cardiac musculature is present in both venae cavae, and they contract together with the atrium, contributing to the pumping mechanism of the heart.

Maternal cardiometabolic dysfunction and fetal sex‐specific alterations to uterine vascular reactivity in an ovine model of obesity during pregnancy

The Journal of Physiology, Volume 604, Issue 12, Page 5011-5030, 15 June 2026.
Abstract figure legend We developed a novel ovine model of diet‐induced maternal obesity, where ewes were fed a control or obesogenic diet for 60 days pre‐pregnancy and throughout gestation. Pregnant ewes were surgically instrumented to assess maternal cardiovascular function near term.

Geometric similarity of aorta, venae cavae, and certain of their branches in mammals

, 1981
The diameters of the aorta and venae cavae at various points throughout their lengths, the diameters of their major branches, and the lengths of various aortic and vena caval segments were measured in plastic corrosion casts of the arterial and venous ...

Unique Constellation of Vascular Anomalies in a Female Cadaver: IVC, Renal Vein, and Left Colic Artery Variation

Surgeries
Embryological development of the vascular system consists of growth and regression of developing vessels, often resulting in numerous variations. This cadaveric case report describes an individual with a duplicated inferior vena cava accompanied by ...

Congenital systemic venous return anomalies to the right atrium review

Insights into Imaging, 2019
Congenital anomalies of the systemic venous return to the right atrium are rare and stem from variations in the embryogenesis of the venous system. They are usually asymptomatic, and such the major clinical significance of their recognition is to prevent
