Physics-informed spectral approximation of Koopman operators [PDF]

arXiv
Koopman operators and transfer operators represent nonlinear dynamics in state space through its induced action on linear spaces of observables and measures, respectively. This framework enables the use of linear operator theory for supervised and unsupervised learning of nonlinear dynamical systems, and has received considerable interest in recent ...

Mitral valve replacement with the preservation of the entire valve apparatus Substituição da valva mitral com preservação do aparato completo da valva

Brazilian Journal of Cardiovascular Surgery, 2007
OBJECTIVE: The papillary muscles and the chordae tendineae of both mitral leaflets contribute to the preservation of the left ventricular function. Most surgeons, however, routinely excise the anterior mitral leaflet. METHODS: In a group of nine patients, six of them underwent mitral valve replacement alone and three underwent both aortic and mitral ...

Classification of Mitral Regurgitation from Cardiac Cine MRI using Clinically-Interpretable Morphological Features [PDF]

arXiv
The assessment of mitral regurgitation (MR) using cardiac MRI, particularly Cine MRI, is a promising technique due to its wide availability. However, some of the temporal information available in clinical Cine MRI may not be fully utilised, as it requires detailed temporal analysis across different cardiac views.

Three-Dimensional Lagrangian Coherent Structures in Patients with Aortic Regurgitation [PDF]

arXiv
Understanding blood transport in cardiovascular flows is important for managing patients with cardiovascular disease. In this study, three-dimensional Lagrangian coherent structures have been extracted for the first time in both healthy patients and patients with aortic regurgitation.
