Vortex formation and instability in the left ventricle [PDF]
We study the formation of the mitral vortex ring during early diastolic filling in a patient-specific left ventricle (LV) using direct numerical simulation. The geometry of the left ventricle is reconstructed from Magnetic Resonance Imaging (MRI) data of a healthy human subject.

Proportion among the segments of the normal tricuspid valve annulus: parameter for valve annuloplasty [PDF]
OBJECTIVE: The purpose of this study was to determine the proportions among the segments of the human tricuspid valve annulus. METHODS: A descriptive autopsy study was made of 30 human hearts without fixation, within six hours of death, without ...

Computational reduction strategies for the detection of steady bifurcations in incompressible fluid-dynamics: applications to Coanda effect in cardiology [PDF]
We focus on reducing the computational costs associated with the hydrodynamic stability of solutions of the incompressible Navier-Stokes equations for a Newtonian and viscous fluid in contraction-expansion channels. In particular, we are interested in studying steady bifurcations, occurring when non-unique stable solutions appear as physical and/or ...

Introduction:Mitral valve repair is the treatment of choice to correct mitral insufficiency, although the literature related to mitral valve annulus behavior after mitral repair without use of prosthetic rings is scarce.Objective:To analyze mitral ...

End stage cardiomyopathy and secondary mitral insufficiency: surgical alternative with prostesis implant and left ventricular remodelling [PDF]
OBJECTIVE: To present a new surgical approach that consists of the implantation of a mitral prosthesis smaller than the annulus with traction of the papillary muscles to reduce the sphericalness of the left ventricle.

Sparse incomplete representations: A novel role for olfactory granule cells [PDF]
Mitral cells of the olfactory bulb form sparse representations of the odorants and transmit this information to the cortex. The olfactory code carried by the mitral cells is sparser than the inputs that they receive. In this study we analyze the mechanisms and functional significance of sparse olfactory codes.
