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.

[Aortic insufficiency due to quadricuspid aortic valve].
Arquivos brasileiros de cardiologia, 1993 In a 45 year old patient with clinic diagnosis of aortic regurgitation the two-dimensional echocardiography demonstrated a quadricuspid aortic valve and severe aortic regurgitation by Doppler. The quadricuspid aortic valve is a rare pathology, usually not associated with other cardiovascular pathologies and in which there is evolution with aortic ...

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.

DEN Open, Volume 6, Issue 1, April 2026.ABSTRACT Loeys‐Dietz syndrome (LDS) is an autosomal dominant connective tissue disorder caused by pathogenic variants in TGFBR1 or TGFBR2. It is characterized by vascular fragility, skeletal abnormalities, and predisposition to allergic and inflammatory conditions, including monogenic inflammatory bowel disease (IBD).

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.

4D Flow MRI Velocity and Turbulence Mapping in Mild Valvular Heart Disease
Journal of Magnetic Resonance Imaging, Volume 63, Issue 1, Page 222-232, January 2026.ABSTRACT Background Valvular heart disease (VHD) commonly leads to the development of turbulent blood flow. Turbulent kinetic energy (TKE), measured with 4D flow MRI, may be a complement to current metrics for early identification of VHD. Purpose To investigate TKE as a marker of VHD in relation to flow velocity and cardiovascular geometry.

Journal of Ultrasound in Medicine, Volume 45, Issue 1, Page 105-113, January 2026.Objectives First‐trimester ultrasound has evolved to incorporate a detailed fetal anatomy scan (FAS) with nuchal translucency (NT) screening. Many institutions use a 2‐visit protocol: NT followed by detailed FAS at 14–16 weeks. We aimed to evaluate whether integrating detailed FAS into the NT window (12 + 5 to 13 + 6 weeks) is non‐inferior in ...
