On the Left Ventricular Remodeling of Patients with Stenotic Aortic Valve: A Statistical Shape Analysis

2021

The left ventricle (LV) constantly changes its shape and function as a response to pathological conditions, and this process is known as remodeling. In the presence of aortic stenosis (AS), the degenerative process is not limited to the aortic valve but also involves the remodeling of LV. Statistical shape analysis (SSA) offers a powerful tool for the visualization and quantification of the geometrical and functional patterns of any anatomic changes. In this paper, a SSA method was developed to determine shape descriptors of the LV under different degrees of AS and thus to shed light on the mechanistic link between shape and function. A total of n=86 patients underwent computed tomography (…

Measurement invariance of the Behavioural Regulation in Sport Questionnaire when completed by young athletes across five European countries

2013

The purpose of this study was (1) to examine the factorial validity of the Behavioural Regulation Sport in Questionnaire (BRSQ) when completed by young soccer players in the Promoting Adolescent Physical Activity (PAPA) project (9-15 years old) in 5 European countries (France: n = 1248, Greece: n = 1507, Norway: n = 1397, Spain: n = 2245, and England: n = 1372) and (2) test the measurement invariance of its latent factors across these 5 countries.First, we tested the exploratory structural equation model (ESEM) factor analyses, allowing cross-loadings between factors, against the traditional independent clusters confirmatory factor analysis model (ICM-CFA), with all cross-loadings constrain…
