INSUFICIÊNCIA CARDÍACA POR VALVOPATIA MITRAL EM DECORRÊNCIA DE FEBRE REUMÁTICA
O coração, nossa bomba ejetora, apresenta complexa anatomia e detalhadas estruturas afim de subsidiar seu papel essencial para a manutenção da vida.

Un mecanismo inusual de complicacion de endocarditis infecciosa (EI) aortica es llamado “kissing abscess”, producido por el impacto del flujo de la regurgitacion aortica y contacto de las vegetaciones sobre la valva anterior mitral.

Foram descritos os achados do exame físico em cães com degeneração mixomatosa crônica da valva mitral e mensurado o comprimento e a espessura das cúspides da valva mitral pelo exame ecocardiográfico. Utilizaram-se 81 cães de diferentes raças de pequeno a

OBJECTIVE: Mitral valve surgery can be performed through the trans-atrial or the trans-septal approach. Although the trans-atrial is the preferred method, the trans-septal approach has also been used recently and has a particular value in beating-heart ...

Troca valvar com preservação de cordas e plástica na cirurgia da insuficiência mitral crônica [PDF]
OBJETIVO: Comparar, clinica e laboratorialmente, três grupos de pacientes submetidos ao tratamento cirúrgico da insuficiência mitral crônica isolada; um grupo submetido à plástica valvar e dois à troca da valva mitral com diferentes técnicas de ...

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.

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 ...

Modeling the Association Structure in Doubly Robust GEE for Longitudinal Ordinal Missing Data [PDF]
Generalized Estimation Equations (GEE) are a well-known method for the analysis of categorical longitudinal responses. GEE method has computational simplicity and population parameter interpretation. In the presence of missing data it is only valid under the strong assumption of missing completely at random.

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.
