Influence of the elevation of the left ventricular diastolic pressure on the values of the first temporal derivative of the ventricular pressure (dP/dt)

Arquivos Brasileiros de Cardiologia, 1999
PURPOSE: To assess the effects of the elevation of the left ventricular end-diastolic pressure (LVEDP) on the value of the 1st temporal derivative of the ventricular pressure (dP/dt). METHODS: Nineteen anesthetized dogs were studied.

Substituição isolada da valva aórtica em pacientes com função ventricular deprimida Aortic valve replacement in patients with depressed left ventricular ejection fraction

Brazilian Journal of Cardiovascular Surgery, 1989
Para avaliar o valor prognóstico da fração de ejeção do ventrículo esquerdo, entre 210 pacientes com lesões da valva aórtica operados, consecutivamente, entre maio de 1981 e outubro de 1988 e que receberam as próteses Omniscience e Meditronic-Hall, foram

Quantification of Trabeculae Inside the Heart from MRI Using Fractal Analysis [PDF]

arXiv, 2018
Left ventricular non-compaction (LVNC) is a rare cardiomyopathy (CMP) that should be considered as a possible diagnosis because of its potential complications which are heart failure, ventricular arrhythmias, and embolic events. For analysis cardiac functionality, extracting information from the Left ventricular (LV) is already a broad field of Medical

Left ventricular global systolic function assessment by echocardiography

Annals of Cardiac Anaesthesia, 2016
The left ventricle, with its thickened myocardial walls, unlike the right ventricle has no measurable geometric shape. It has a conical apex and its function quantification, needs intensive, 2D, 3D and M mode transesophageal echocardiography, which is ...

An Anticoagulant Coating Based on a Block Phosphocholine Copolymer for Potential Applications in Blood Contact Devices

Advanced Materials Interfaces, EarlyView.
Anticoagulant properties are critical for blood‐compatible materials, and anticoagulant coatings are a common key issue for blood‐contacting medical devices. In this study, a block copolymer poly(2‐methacrylenoxyethyl phosphocholine‐b‐glycidyl) (PMPC‐b‐GMA) is synthesized, using reversible addition‐fragmentation chain transfer polymerization (RAFT) and

Using Anatomical Markers for Left Ventricular Segmentation of Long Axis Ultrasound Images [PDF]

arXiv, 2015
Left ventricular segmentation is essential for measuring left ventricular function indices. Segmentation of one or several images requires an initial guess of the contour. It is hypothesized here that creating an initial guess by first detecting anatomical markers, would lead to correct detection of the endocardium.

Effect of the use and timing of bone marrow mononuclear cell delivery on left ventricular function after acute myocardial infarction: the TIME randomized trial.

Journal of the American Medical Association (JAMA), 2012
CONTEXT While the delivery of cell therapy after ST-segment elevation myocardial infarction (STEMI) has been evaluated in previous clinical trials, the influence of the timing of cell delivery on the effect on left ventricular function has not been ...
