Implementation of an epicardial implantable MEMS sensor for continuous and real-time postoperative assessment of left ventricular activity in adult minipigs over a short- and long-term period
The sensing of left ventricular (LV) activity is fundamental in the diagnosis and monitoring of cardiovascular health in high-risk patients after cardiac surgery to achieve better short- and long-term outcome. Conventional approaches rely on noninvasive me ...
Aip Publishing2024Effect of the structural modification of Candesartan with Zinc on hypertension and left ventricular hypertrophy
Nikolaos Stergiopoulos, Augusto Martins Lima, Valeria Romina Martinez
Hypertension is the most common cause of left ventricular hypertrophy, contributing to heart failure progression. Candesartan (Cand) is an angiotensin receptor antagonist widely used for hypertension treatment. Structural modifications were previously perf ...
ELSEVIER2023Design 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 SA2023Biomechanics of diastolic dysfunction: a one-dimensional computational modeling approach
Nikolaos Stergiopoulos, Georgios Rovas, Vasiliki Bikia, Stamatia Zoi Pagoulatou
Diastolic dysfunction (DD) is a major component of heart failure with preserved ejection fraction (HFpEF). Accordingly. a profound understanding of the underlying biomechanical mechanisms involved in DD is needed to elucidate all aspects of HFpEF. In this ...
AMER PHYSIOLOGICAL SOC2020Hemodynamics of ageing, ventricular-arterial coupling and noninvasive assessment of key hemodynamical and cardiac quantities
Ageing is a natural process that affects both the anatomical and functional properties of the cardiovascular system and alters the coupling characteristics between the heart and the aorta. These alterations may predispose the cardiovascular system in the d ...
EPFL2020Noninvasive Stroke Volume Monitoring by Electrical Impedance Tomography
In clinical practice it is of vital importance to track the health of a patient's cardiovascular system via the continuous measurement of hemodynamic parameters. Cardiac output (CO) and the related stroke volume (SV) are two such parameters of central inte ...
EPFL2018Divergent patterns of atrial ECG organization during catheter ablation of persistent atrial fibrillation revealed by adaptive harmonic frequency schemes
Jean-Marc Vesin, Adrian Luca, Andréa Buttu, Etienne Pruvot
Introduction: We hypothesized that organization indices based on the analysis of atrial ECG harmonic components may help identify patients (pts) with persistent AF (pAF) unresponsive to pulmonary vein isolation (PVI) and left atrial (LA) ablation. Using ad ...
2016Thermodynamically consistent orthotropic activation model capturing ventricular systolic wall thickening in cardiac electromechanics
Alfio Quarteroni, Ricardo Esteban Ruiz Baier, Toni Mikael Lassila, Simone Rossi, Adélia Sequeira
The complex phenomena underlying mechanical contraction of cardiac cells and their influence in the dynamics of ventricular contraction are extremely important in understanding the overall function of the heart. In this paper we generalize previous contrib ...
Elsevier2014Endothelial deletion of murine Jag1 leads to valve calcification and congenital heart defects associated with Alagille syndrome
The Notch signaling pathway is an important contributor to the development and homeostasis of the cardiovascular system. Not surprisingly, mutations in Notch receptors and ligands have been linked to a variety of hereditary diseases that impact both the he ...
Company of Biologists2012The Role of Atrial Modeling in the Development of ECG Processing Tools
Jean-Marc Vesin, Mathieu Lemay, Laurent Renaud Uldry, Cédric Duchene, Vincent Jacquemet, Lukas Kappenberger
The standard ECG remains the most common non-invasive tool for assessing atrial fibrillation. Specific signal processing techniques have been developed to improve the diagnosis. However, validation of such tools is challenging and comprehensive invasive da ...
