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...
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...
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...
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...
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...

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...
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 ...

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...
