Desenlaces posquirúrgicos de pacientes con disfunción ventricular derecha e hipertensión pulmonar sometidos a cambio valvular mitral

Rev. chil. anest; 52 (1), 2023
OBJECTIVE: To describe the postoperative clinical outcomes of patients with right ventricular dysfunction and pulmonary hypertension who undergo mitral valve replacement surgery. METHODOLOGY: Descriptive, longitudinal, retrospective study. Patients older than 18 years, who underwent mitral valve replacem...

Chronic Obstructive Pulmonary Disease: The Role of Myocardial Deformation Indices and Right Ventricle Three-Dimensional Echocardiography

Abstract Background: Right ventricular dysfunction is a major complication in chronic obstructive pulmonary disease (COPD) and, despite its prognostic implications, is rarely considered in routine clinical analysis. Objectives: To compare RV function variables with standard and advanced echocardiograph...

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...

Thrombolysis in acute pulmonary embolism

SUMMARY OBJECTIVES Acute pulmonary embolism (APE) is an important cause of cardiovascular mortality, due mainly to hemodynamic instability. In these cases, the recommendation is to perform some reperfusion procedure, with systemic thrombolysis being the main therapy used. However, national data evaluat...

Early and long-term outcomes of surgical treatment of ebstein's anomaly

Abstract Objective: This study aimed to evaluate Ebstein's anomaly surgical correction and its early and long-term outcomes. Methods: A retrospective analysis of 62 consecutive patients who underwent surgical repair of Ebstein's anomaly in our institution from January 2000 to July 2016. The following l...

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...

Resonancia magnética cardíaca en el seguimiento alejado de pacientes con tetralogía de Fallot

Rev. chil. pediatr; 89 (3), 2018
INTRODUCCIÓN: La tetralogía de Fallot (TF) es la cardiopatía congénita cianótica más frecuente. La insuficiencia pulmonar (IP) y dilatación del ventrículo derecho (VD) son las complicaciones más frecuentes a largo plazo. La resonancia magnética cardiaca (RMC) es el "gold standard" para la evalu...

Evaluación ecocardiográfica de pacientes pediátricos post-trasplante cardiaco en Chile: Aplicación inicial de un protocolo funcional con Strain longitudinal global

Rev. chil. pediatr; 89 (1), 2018
Resumen: Introducción: La evaluación ecocardiográfica de pacientes post-trasplante cardiaco pediátrico es una herramienta útil. Sin embargo, aún es necesario definir un protocolo óptimo de seguimiento. Obje tivo: Caracterizar los resultados de la aplicación de un protocolo de evaluación ecoc...

Analysis of dyssynchrony and ventricular function in right univentricular stimulation at different positions

Abstract Introduction: Chronic stimulation of the right ventricle with pacemaker is associated with ventricular dyssynchrony and loss of contractility, even in subjects without previous dysfunction. In these patients, there is a debate of which pacing site is less associated with loss of ventricular fun...

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...
