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.

Early outcomes of aortic valve neocuspidization (the Ozaki procedure): Initial experience of a single centre

Indian Heart Journal
Introduction: Aortic valve neocuspidization (AVNeo) using fixed autologous pericardium, also known as the Ozaki technique, is an effective therapy for treating aortic valvulopathies.

Deletion of the TRPV1 channel attenuates afferent renal nerve responses to renal artery occlusion but not elevated renal pelvic pressure

The Journal of Physiology, EarlyView.
Abstract figure legend Using wild‐type and Trpv1−/− rats, we assessed the contribution of TRPV1 channels to the activation of afferent renal nerve activity (ARNA) during renal artery occlusion, graded reductions in renal blood flow and elevated renal pelvic pressure.

Statins for aortic valve stenosis

São Paulo Medical Journal
BACKGROUND: Aortic valve stenosis is the most common type of valvular heart disease in the USA and Europe. Aortic valve stenosis is considered similar to atherosclerotic disease. Some studies have evaluated statins for aortic valve stenosis. OBJECTIVES:

Versatile and Highly Efficient MRI Simulation of Arbitrary Motion in KomaMRI

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1791-1803, March 2026.
ABSTRACT Purpose To extend the KomaMRI simulator with motion capabilities that enable the simulation of both simple, parametrizable motion patterns and arbitrarily complex spin trajectories. Additionally, we introduce a novel file format for storing and sharing dynamic digital phantoms.

Coronary Artery Blood Flow Imaging Using 3D Flow MRI

Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1545-1559, March 2026.
ABSTRACT Purpose In this work, a 3D phase contrast (PC) technique is presented, which enables flow velocity measurements in three spatial directions, simultaneously covering the proximal left (LCA) and right (RCA) coronary arteries and yielding both morphological and flow information.
