Correction of left ventricular outflow tract obstruction caused by anomalous papillary muscle and subaortic membrane

Abstract This paper presents a case study of a 30-year-old male patient with dyspnea on exertion had echocardiographic diagnosis of aortic subvalvar stenosis. Discrete mitral regurgitation and aortic valve dysplasia with mild to moderate insufficiency and hypertrophic cardiomyopathy were also noted. Duri...

Combined mitral valve replacement and ravitch procedures in a patient with previous pneumonectomy: case report and review of the literature

Abstract Introduction: Significant anatomical and functional changes occur following pneumonectomy. Mediastinal structures displace toward the side of the resected lung, pulmonary reserve is reduced. Owing to these changes, surgical access to heart and great vessels becomes challenging, and there is inc...

Should sinus of valsalva be replaced in patients with dilated ascending aorta and aortic valve diseases?

Abstract Introduction: The aim of this study is to investigate the change in the dimension of sinus of Valsalva in patients who underwent supracoronary ascending aorta replacement with aortic valve replacement. Methods: A total of 81 patients who underwent supracoronary ascending aorta replacement with...

Echocardiographic Study of the Coronary Sinus in the Indeterminate Form of Chagas Disease

Abstract INTRODUCTION: We investigated the occurrence of coronary sinus abnormalities in the indeterminate form of Chagas disease (CD). METHODS: Differences between the maximum and minimum diameters of the coronary sinus (∆%) on echocardiography were evaluated in individuals with the indetermin...

Concordancia de la motilidad segmentaria evaluada por ecocardiograma transtorácico y resonancia magnética cardíaca en pacientes con infarto agudo de miocardio

Rev. colomb. cardiol; 25 (6), 2018
Resumen Introducción: La evaluación de la contractilidad segmentaria es un marcador importante para determinar la extensión de la enfermedad coronaria manifestada a través de un evento isquémico cardiaco. La resonancia magnética cardíaca es el patrón estándar para evaluar dicha motilidad; sin ...

Corrección quirúrgica exitosa de ruptura de aneurisma del seno de Valsalva Sakakibara tipo IV y cierre de comunicación interventricular perimembranosa

Rev. colomb. cardiol; 25 (6), 2018
Resumen El aneurisma del seno de Valsalva es una anomalía cardíaca que puede ser congénita o adquirida. Es referido como una anomalía congénita rara, usualmente asintomática detectada en un ecocardiograma 2 D de rutina, hasta presentaciones relacionadas con la compresión de estructuras adyacentes ...

En el modelo preclínico de insuficiencia cardíaca por disfunción sistólica en ratón (coartación de aorta torácica) la velocidad de flujo carotídeo determinada precozmente se asocia a función ventricular izquierda tardía

Rev. chil. cardiol; 37 (3), 2018
Resumen: Los modelos experimentales de falla cardíaca con fracción de eyección disminuida en murinos son pocos. Uno de estos modelos es el de coartación de la aorta torácica en el arco aórtico (COA) en ratones. Un aspecto importante en su desarrollo es la evaluación precoz del procedimiento y su r...

Uso de ecocardiografia junto ao leito para medir índices cardíaco e de resistência vascular sistêmica em pacientes pediátricos com choque séptico

RESUMO Objetivo: Acompanhar o índice cardíaco e o índice de resistência vascular sistêmica até a ressuscitação. Métodos: Por meio de ecocardiografia junto ao leito, obteve-se um conjunto de parâmetros hemodinâmicos, inclusive débito cardíaco, volume sistólico, índice cardíaco, índice d...

Does percutaneous left atrial appendage closure affect left atrial performance?

Background: Percutaneous left atrial appendage (LAA) occlusion may be an alternative therapy for atrial fibrillation (AF) patients with contraindication for anti-coagulation therapy. However, the influence of LAA occlusion on left atrial (LA) performance has not been studied. Objective: Our aim was t...
