Collagen fibers are essential structural components of mitral valve leaflets, their tension
apparatus (chordae tendineae), and the associated papillary muscles. Excess or lack of …

Intra-ventricular flow dynamics has recently emerged as an important evaluation and
diagnosis tool in different cardiovascular conditions. The formation of vortex pattern during …

Purpose To present and validate a new method for 4D flow quantification of vortex‐ring
mixing during early, rapid filling of the left ventricle (LV) as a potential index of diastolic …

Paravalvular leak (PVL) is a complication of transcatheter aortic valve replacement. Despite
its marked clinical impact, no previous study has reported how PVL affects the …

Prior studies have shown that in a healthy heart, there exist a large asymmetric vortex
structure that aids in establishing a steady flow field in the left ventricle. However, the …

Background In vivo characterization of mitral valve dynamics relies on image analysis
algorithms that accurately reconstruct valve morphology and motion from clinical images …

Objectives Transcatheter mitral valve prostheses are designed to capture the anterior leaflet
and surgical techniques designed to fully preserve the subvalvular apparatus at prosthetic …

A prosthetic mitral valve designed to resemble a patient's nat-ural mitral valve is provided.
The prosthetic mitral valve includes an asym-metrical, flexible ring dimensioned to match a …

This thesis, taking place in the context of the Mivana project, is devoted to the modeling and
to the numerical simulation of implantable cardiovascular devices. This project is led by the …

OBJECTIVES During mitral valve replacement, the anterior mitral leaflet is usually resected
or modified. Anterior leaflet splitting seems the least disruptive modification. Reattachment of …
