Deep Learning Pipeline for Preprocessing and Segmenting Cardiac Magnetic Resonance of Single Ventricle Patients from an Image Registry [PDF]
, 2023 Purpose: To develop and evaluate an end-to-end deep learning pipeline for segmentation and analysis of cardiac magnetic resonance images to provide core-lab processing for a multi-centre registry of Fontan patients. Materials and Methods: This retrospective study used training (n = 175), validation (n = 25) and testing (n = 50) cardiac magnetic ...

STUDY OF THE DIFFERENCES IN THE ARTERIAL BLOOD PRESSURE VALUES IN HEALTHY PEOPLE MEASURED SIMULTANEOUSLY ON LEFT AND RIGHT ARMS [PDF]
Journal of IMABArterial blood pressure measurement constitutes a fundamental aspect of nursing practice. The clinical significance of this measurement lies in its ability to assess systolic and diastolic blood pressure, which serve as crucial indicators of ...

Local extremality of the Calabi-Croke sphere for the length of the shortest closed geodesic [PDF]
, 2009 Recently, F. Balacheff proved that the Calabi-Croke sphere made of two flat 1-unit-side equilateral triangles glued along their boundaries is a local extremum for the length of the shortest closed geodesic among the Riemannian spheres with conical ...

Analysis of left ventricular behaviour in diastole by means of finite element method [PDF]
, 1979 The human left ventricle in diastole can be modelled as a passive structure with incremental internal pressure change being considered as the load. Recent developments in engineering stress analysis provide techniques for predicting the behaviour of ...

Quasi-static imaged-based immersed boundary-finite element model of human left ventricle in diastole [PDF]
, 2014 SUMMARY: Finite stress and strain analyses of the heart provide insight into the biomechanics of myocardial function and dysfunction. Herein, we describe progress toward dynamic patient-specific models of the left ventricle using an immersed boundary ...

Diastolic dysfunction in hypertension
Hipertensión y Riesgo Vascular, 2017 Hypertension and coronary heart disease, often coexisting, are the most common risk factors for heart failure. The progression of hypertensive heart disease involves myocardial fibrosis and alterations in the left ventricular geometry that precede the functional change, initially asymptomatic.
