Taquicardia por reentrada ramo ramo

A taquicardia por reentrada ramo a ramo, apesar de ter sido descrita há cerca de 30 anos, é entidade por vezes desconhecida de muitos cardiologistas e, por vezes, não identificada por eletrofisiologistas. Provavelmente subdiagnosticada, em especial nos portadores de cardiomiopatia dilatada, essa entid...

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...

Impact of dexmedetomidine on hemodynamics in rabbits

Acta cir. bras; 33 (4), 2018
Abstract Purpose: To evaluate the effects of single intravenous administration of Dexmedetomidine (DEX) on hemodynamics in rabbits. Methods: A total of 32 New Zealand white rabbits were randomly divided into the control group (Group C), Group D1 (2.75 μg/kg), Group D2 (5.5 μg/kg), and Group ...

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 ...

Influence of Aerobic Training on The Mechanics of Ventricular Contraction After Acute Myocardial Infarction: A Pilot Study

Arq. bras. cardiol; 110 (4), 2018
Abstract The study of myocardial contractility, based on the new anatomical concepts that govern cardiac mechanics, represents a promising strategy of analysis of myocardial adaptations related to physical training in the context of post-infarction. We investigated the influence of aerobic training on ph...

Mesenchymal stem cells reduce left ventricular mass in rats with doxorubicin-induced cardiomyopathy

Int. j. morphol; 36 (1), 2018
SUMMARY: Doxorubicin is a drug that used by a majority in the treatment of carcinomas. The most obvious known side effect is cardiomyopathy. Many studies have been carried out to eliminate side effects of the doxorubicin, and stem cell studies have been added in recent years. In this study, it was aimed ...

Ventrículo izquierdo no compacto: panorámica y arritmogenia

CorSalud; 10 (1), 2018
Las miocardiopatías constituyen un grupo importante y heterogéneo de enfermedades del miocardio asociadas a disfunción mecánica, eléctrica, o ambas. El ventrículo izquierdo no compacto es una miocardiopatía familiar de etiología incierta de la que se desconocen sus exactas incidencia y prevalenci...

Global Longitudinal Strain Accuracy for Cardiotoxicity Prediction in a Cohort of Breast Cancer Patients During Anthracycline and/or Trastuzumab Treatment

Arq. bras. cardiol; 110 (2), 2018
Abstract Background: The high cardiotoxicity morbidity and mortality rates associated with the antineoplastic therapy for breast cancer could be reduced with the early use of cardioprotective drugs. However, the low sensitivity of left ventricular ejection fraction limits its use in that preventive stra...
