Correlação ecocardiográfica da função diastólica do ventrículo direito com idade e gênero em indivíduos com função sistólica preservada

ABC., imagem cardiovasc; 34 (2), 2021
Introdução: As funções sistólica e diastólica do ventrículo direito influenciam no desfecho de doenças cardiovasculares. A avaliação sistemática das dimensões e da função das câmaras direitas, de acordo com sexo e idade, não é uniformemente realizada. Objetivo: Avaliar, ao ecocardiograma...

Caracterización de la fisiología restrictiva del ventrículo derecho mediante flujo 4D

Rev. chil. cardiol; 39 (2), 2020
Abstract: Right ventricular restrictive physiology (RVRP) occurs in diverse clinical scenarios, most frequently after repair of Tetralogy of Fallot (TOF). Cardiac magnetic resonance (CMR) can comprehensively evaluate RVRP using 4D flow along with anatomical and fibrosis characterization. Also, RVRP is as...

Echocardiographic Correlation between Right Ventricular Function and Left Atrial Volume

Arq. bras. cardiol; 112 (3), 2019
Abstract Background: Few reports exist on the relationship of the left ventricular diastolic dysfunction (LVDD) with its most important features including enlargement of the left atrium and left ventricular hypertrophy (LVH), and with the right ventricular (RV) function. Objective: To determine the cor...

Análisis función ventricular derecha, función renal y fluidos tras resucitación en pacientes con ventilación mecánica

Rev. chil. anest; 48 (3), 2019
INTRODUCTION: Hemodynamic optimization is a main goal in the management of critically ill patients. Right ventricular function, renal failure and fluid balance are part of this process. Our goal is to analysis those, after the initial resuscitation. MATERIAL AND METHODS: A prospective, observational stud...

Echocardiographic assessment of right ventricular function by two-dimensional strain in patients with left-sided valvular heart disease: comparison whit three-dimendional echocardiography

Background: Right ventricular (RV) dysfunction is a well-known predictor of mortality in patients with valvular heart disease (VHD). The assessment of RV function is often difficult due to complex geometry and hemodynamic factors. Objective: We aim to analyze RV function in patients with severe mitral an...

Early Assessment of Right Ventricular Function in Systemic Lupus Erythematosus Patients using Strain and Strain Rate Imaging

Arq. bras. cardiol; 111 (1), 2018
Abstract Background: Right ventricular function is a crucial factor of the prognosis of systemic lupus erythematosus (SLE). Objectives: To evaluate the right ventricular function in SLE patients with different degrees of pulmonary hypertension (PH) by strain and strain rate imaging. Methods: A total o...

Electrical approach to improve left ventricular activation during right ventricle stimulation

Medicina (B.Aires); 77 (1), 2017
Coronary sinus mapping is commonly used to evaluate left atrial activation. Herein, we propose to use it to assess which right ventricular pacing modality produces the shortest left ventricular activation times (R-LVtime) and the narrowest QRS widths. Three study groups were defined: 54 controls without ...

Fractal Dimension in Quantifying Experimental-Pulmonary-Hypertension-Induced Cardiac Dysfunction in Rats

Arq. bras. cardiol; 107 (1), 2016
Abstract Background: Right-sided heart failure has high morbidity and mortality, and may be caused by pulmonary arterial hypertension. Fractal dimension is a differentiated and innovative method used in histological evaluations that allows the characterization of irregular and complex structures and the...

Valor prognóstico da disfunção ventricular diastólica em pacientes com sepse grave e choque séptico

RESUMO Objetivo: Avaliar a prevalência de disfunção miocárdica e seu valor prognóstico em pacientes com sepse grave e choque séptico. Métodos: Pacientes sépticos adultos, admitidos em uma unidade de terapia intensiva, foram estudados de forma prospectiva por meio de ecocardiografia transtorácica...
