Elucidating the cellular determinants of the end‐systolic pressure‐volume relationship of the heart via computational modelling

The Journal of Physiology, EarlyView.
Abstract figure legend Using a multiscale computational model of left ventricular electromechanics, we investigated how sarcomere dynamics influence the end‐systolic pressure‐volume (ESPV) relationship in ejecting beats compared to isovolumetric beats.

Impella 5.5 Use in the Setting of Severe Aortic Insufficiency: A Relative Contraindication

Annals of Thoracic Surgery Short Reports
Moderate or severe aortic insufficiency is a contraindication to transvalvular Impella left ventricular assist device (Abiomed) use out of concern for worsening valvular insufficiency and recirculation. This report describes the case of a 75-year-old man

Balloon valvuloplasty of aortic valve stenosis in childhood: early and medium term results [PDF]

, 2018
Background: Isolated aortic valve stenosis in childhood is treated by balloon valvuloplasty. The role of independent risk factors for the outcome remains unclear.

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

Post‐exercise ketone supplementation improves endurance performance and mitochondrial adaptations during an 8‐week endurance training intervention

The Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐eight trained males completed 8 weeks of supervised indoor cycling training, receiving post‐exercise and pre‐sleep ketone monoester (KE, n = 14) or isocaloric placebo (CON, n = 14). Both groups improved 30 min time‐trial performance with training, but KE achieved a 4% higher power output than CON at the end of the training

Marfan Syndrome Associated With Intellectual Disability and Behavioral Anomalies: Further Evidence for the Effect of Compound Heterozygous Variants in FBN1 on Phenotypic Severity

American Journal of Medical Genetics Part A, Volume 200, Issue 5, Page 1021-1035, May 2026.
ABSTRACT Marfan syndrome (MFS) is a rare connective tissue disorder characterized by involvement of the cardiovascular, ocular, and musculoskeletal systems. Pathogenic variants in FBN1 cause most of the MFS cases; however, intellectual disability (ID) is rarely observed. A non‐consanguineous Pakistani family with four affected individuals was recruited.

Aortic Valvuloplasty for Incomplete Quadricuspid Aortic Valve Using Tricuspidization by Folding the Accessory Cusp

Annals of Thoracic Surgery Short Reports
We describe a young patient with incomplete quadricuspid aortic valve, poor medication adherence, and multiple dental caries. Aortic valve repair was selected over replacement and successfully performed by tricuspidization, folding the accessory cusp ...

Mixed Reality‐Assisted Thoracic Endovascular Aortic Repair: A Retrospective Study on Efficacy and Safety

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
This study demonstrates the significant clinical utility of Mixed Reality (MR) in Thoracic Endovascular Aortic Repair (TEVAR). Our findings reveal that MR‐assisted workflows enhance patient comprehension and satisfaction preoperatively and provide intuitive intraoperative navigation.

A Meta‐Analysis and Simplified Nomenclature for Diagonal Coronary Artery and Ramus Intermedius Across Adult and Pediatric Hearts

Clinical Anatomy, Volume 39, Issue 3, Page 305-324, April 2026.
ABSTRACT Anatomical descriptions of left‐sided oblique coronary branches remain inconsistent, hindering imaging interpretation and surgical planning. To quantify the prevalence, branching patterns and morphometry of the ramus intermedius (RI) and diagonal branches, and propose a unified nomenclature.
