Is There any Relationship Between Myocardial Repolarization Parameters and the Frequency of Ventricular Premature Contractions?

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: Ventricular premature contractions (VPCs) may trigger lethal ventricular arrhythmias in patients with structural heart disease. However, this role of VPCs in healthy people remains controversial once that not enough clinical trials are available. Recently, some myocardial repolariza...

Pressure Overload-induced Cardiac Hypertrophy Varies According to Different Ligation Needle Sizes and Body Weights in Mice

Arq. bras. cardiol; 110 (6), 2018
Abstract Background: The cardiac hypertrophy (CH) model for mice has been widely used, thereby providing an effective research foundation for CH exploration. Objective: To research the effects of CH modeling under abdominal aortic constriction (AAC) using different needles and weights in mice. Methods...

Metastatic adenocarcinoma involving the right ventricle and pulmonary artery leading to right heart failure: case report

Säo Paulo med. j; 136 (3), 2018
ABSTRACT CONTEXT: Obstruction of the right ventricular outflow tract due to metastatic disease is rare. Clinical recognition of cardiac metastatic tumors is rare and continues to present a diagnostic and therapeutic challenge. CASE REPORT: We present the case of a patient who had severe respiratory ins...

Cardiomiopatia não compactada: doença do nó sinusal como manifestação inicial tratada com marcapasso

A cardiomiopatia não compactada é uma doença congênita, que resulta de falha da compactação do miocárdio na vida embrionária. Nesse processo, há a persistência de trabeculações e recessos profundos, que se comunicam com a cavidade ventricular e geram espessamento do miocárdio em duas camadas...

Vascular endothelial growth factor association with angiopoietin 1 promotes improvement in ventricular function after ischemic cardiomyopathy induced in mini pigs

Acta cir. bras; 33 (4), 2018
Abstract Purpose: To investigate the safety and clinical, hemodynamic and tissue improvement ability in mini pigs undergoing cell and gene therapy for the treatment of acute myocardial infarction. Methods: Thirty-two mini pigs Br1 lineage, 12 months old, undergoing induction of acute myocardial infarct...

Origen anómalo de la arteria coronaria derecha desde el tronco de la arteria pulmonar (ARCAPA)

Arch. pediatr. Urug; 89 (2), 2018
Las anomalías de las arterias coronarias son una condición clínica de muy baja incidencia y de estas el origen anómalo de la arteria coronaria derecha desde el tronco de la arteria pulmonar (ARCAPA) representa cerca de 0,002% en la población general. Se puede asociar a la presencia de otras anomalí...

Application of circular patch plasty (dor procedure) or linear repair techniques in the treatment of left ventricular aneurysms

Abstract Objective: The aim of this study was to evaluate early clinical outcomes and echocardiographic measurements of the left ventricle in patients who underwent left ventricular aneurysm repair using two different techniques associated to myocardial revascularization. Methods: Eighty-nine patients ...

Utilidad de la ecocardiografía en la detección de la insuficiencia cardiaca en un adulto joven con síndrome de origen anómalo de la arteria coronaria izquierda del tronco de la arteria pulmonar y válvula mitral asimétrica similar al paracaídas

Rev. colomb. cardiol; 25 (2), 2018
Resumen Objetivo: describir un caso de un paciente joven con insuficiencia cardiaca, secundaria a dos malformaciones cardiacas infrecuentes, síndrome de ALCAPA y válvula mitral asimétrica, parecida al paracaídas, resaltando la utilidad de la ecocardiografía. Métodos: se analiza el caso a la luz...
