The Impact of Left Ventricular Performance and Afterload on the Evaluation of Aortic Valve Stenosis: A 1D Mathematical Modeling Approach
The transaortic valvular pressure gradient (TPG) plays a central role in decision-making for patients suffering from severe aortic stenosis. However, the flow-dependence nature of the TPG makes the diagnosis of aortic stenosis challenging since the markers ...
MDPI2023Design and computational optimization of compliance-matching aortic grafts
Nikolaos Stergiopoulos, Georgios Rovas, Vasiliki Bikia
Introduction: Synthetic vascular grafts have been widely used in clinical practice for aortic replacement surgery. Despite their high rates of surgical success, they remain significantly less compliant than the native aorta, resulting in a phenomenon calle ...
FRONTIERS MEDIA SA2023Compliance-matching vascular grafts with personalization potential
Aortic diseases are characterized by dire prognosis and inadequate diagnosis, owing to their insidious yet lethal nature. Aortopathies, namely aortic aneurysms and dissections, along with certain congenital diseases, might necessitate surgical replacement ...
EPFL2023Cardiac output estimated from an uncalibrated radial blood pressure waveform: validation in an in-silico-generated population
Nikolaos Stergiopoulos, Georgios Rovas, Vasiliki Bikia
Background: Cardiac output is essential for patient management in critically ill patients. The state-of-the-art for cardiac output monitoring bears limitations that pertain to the invasive nature of the method, high costs, and associated complications. Hen ...
FRONTIERS MEDIA SA2023p-Aminobenzamidine attenuates cardiovascular dysfunctions in spontaneously hypertensive rats
Nikolaos Stergiopoulos, Fabiana Pereira Da Costa Fraga, Allancer Divino De Carvalho Nunes
Aims:Diminazene aceturate, a putative ACE2 activator, is susceptible to cleavage resulting in the formation of paminobenzamidine (PAB). This study aimed to investigate the effects of PAB in addressing cardiovascular dysfunctions in spontaneously hypertensi ...
