RESUMEN: ANTECEDENTES: La valvuloplastía aórtica es un procedimiento paliativo o como puente al reemplazo aórtico percutáneo o quirúrgico. Nuestro abordaje incluye una técnica minimalista y la utilización de balones de mayor tamaño que lo estándar. OBJETIVO: Evaluar los resultados clínicos inme...
Abstract Objective: The aim of this study was to evaluate the QT dispersion and echocardiographic parameters in patients before and after transcatheter aortic valve implantation (TAVI). Methods: One hundred and fifty-two patients with severe aortic valve stenosis (AS) were included in our study. Ninety...
Abstract Background: Simplified projected aortic valve area (EOAproj) is a valuable echocardiographic parameter in the evaluation of low flow low gradient aortic stenosis (LFLG AS). Its widespread use in clinical practice is hampered by the laborious process of flow rate (Q) calculation. Objetive: This...
A cabergolina e a bromocriptina são drogas dopaminérgicas derivadas do ergot e utilizadas para tratamento de distúrbios hiperprolactinêmicos idiopáticos ou adenomas hipofisários, cujo mecanismo de ação é decorrente da redução da secreção de prolactina. Alguns relatos na literatura demonstram...
The quadricuspid aortic valve is a rare congenital anomaly, usually presenting as an isolated malformation causing aortic regurgitation in the faith or sixth decades of life. The first reported cases were found at autopsy or became evident by surgical findings. However, the emergence of new imaging modal...
Abstract Objective: This work describes the experimental validation of a cardiac simulator for three heart rates (60, 80 and 100 beats per minute), under physiological conditions, as a suitable environment for prosthetic heart valves testing in the mitral or aortic position. Methods: In the experiment,...
