Left Ventricular Trabeculations Decrease the Wall Shear Stress and Increase the Intra-Ventricular Pressure Drop in CFD Simulations [PDF]

Frontiers in Physiology, 2018
The aim of the present study is to characterize the hemodynamics of left ventricular (LV) geometries to examine the impact of trabeculae and papillary muscles (PMs) on blood flow using high performance computing (HPC). Five pairs of detailed and smoothed

Estimating Left Ventricular Filling Pressure by Echocardiography

Journal of the American College of Cardiology, 2017
The diagnosis of heart failure may be challenging because symptoms are rather nonspecific. Elevated left ventricular (LV) filling pressure may be used to confirm the diagnosis, but cardiac catheterization is often not practical. Echocardiographic indexes are therefore used as markers of filling pressure.This study investigated the feasibility and ...

Invasive Right Ventricular Pressure-Volume Analysis: Basic Principles, Clinical Applications, and Practical Recommendations

Circulation: Heart Failure, 2021
Supplemental Digital Content is available in the text. Right ventricular pressure-volume (PV) analysis characterizes ventricular systolic and diastolic properties independent of loading conditions like volume status and afterload.

Predictive Value of Right Ventricular Pressure Measurement for Residual Pulmonary Stenosis in Tetralogy Repair

Siriraj Medical Journal, 2022
Objective: The long-term outcome of tetralogy of Fallot repair depends on an adequate relief of right ventricular outflow tract obstruction and preservation of the pulmonary valve function.

Actividad inotrópica inducida por el derivado carbamacepina-alquino en un modelo de corazón aislado y perfundido a flujo constante

Biomédica: revista del Instituto Nacional de Salud, 2011
Introducción. Existen pocos datos con respecto a los efectos de la carbamacepina y sus derivados en el aparato cardiovascular; además, el mecanismo molecular y su sitio de acción celular no son claros. Objetivo.
