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.

The influence of delayed ventricular activation on cardiac repolarization: Insights from electrocardiographic imaging

The Journal of Physiology, EarlyView.
Abstract figure legend This study examines the relationships between activation and repolarization times in epicardial reconstructed unipolar electrograms derived from ECG‐imaging in patients with normal and delayed ventricular activation. In patients with a narrow QRS‐complex, ECG‐imaging reveals significant variability in the activation ...

In vitro characterization of hemodynamics in bicuspid aortic valves: The impact of valve and ascending aortic morphologies

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 411-429, January 2026.
Abstract Purpose This study investigated the effect of bicuspid aortic valve (BAV) morphology and ascending aortic curvature (AAAc) bending angles on aortic hemodynamics, focusing on transvalvular jets and secondary helical flows that contribute to systolic hemodynamic stress linked to aortic complications.

Dextran vs. Crystalloid Priming Solution in Cardiac Surgery: A Randomized Trial on Acute Kidney Injury

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 1, January 2026.
ABSTRACT Background Acute kidney injury (AKI) is a frequent complication following cardiac surgery involving cardiopulmonary bypass (CPB). This is partly attributable to crystalloid‐based priming solutions causing both hemolysis and loss of oncotic pressure with tissue edema. While colloids like albumin and starches have not shown clear benefits, pilot
