INTRODUÇÃO: As doenças cardiovasculares representam a principal causa de mortalidade no mundo. O manejo adequado do Infarto Agudo Miocárdio é pautado na pronta desobstrução da coronária lesionada através de Angioplastia Transluminal Coronária garantindo o fluxo em região, além da reversão e ...
BACKGROUND: Percutaneous mitral balloon commissurotomy (PMBC) remains the preferred treatment for patients with severe symptomatic rheumatic mitral stenosis (MS) and suitable anatomy. The objective of this study was to propose a new score for the prediction of immediate and late success. METHODS. This is...
BACKGROUND: Transcatheter aortic valve replacement (TAVR) with the ACURATE neo device has been associated with a non-negligible incidence of paravalvular aortic regurgitation (AR). The new-generation ACURATE neo2 has been designed to mitigate this limitation. AIMS: The aim of the study was to compare TAV...
BACKGROUND: Exercise tests are an important tool in the investigation of myocardial ischemia. The ramp protocol has gained increasing importance in clinical practice because of the possibility of individualizing its exercise intensity. OBJECTIVE: To assess and compare the sensitivity, specificity, and ac...
INTRODUÇÃO: O termo MINOCA (infarto do miocárdio sem obstrução coronária significativa), recentemente incorporado a 4ª Definição Universal de Infarto do Miocárdio, tem despertado crescente interesse, pois é um diagnóstico sindrômico que inclui diversas causas, cardíacas e não cardíacas. C...
OBJECTIVES: To explore the rate, the determinants of success, and the hemodynamic impact of balloon postdilatation (BPD) of self-expanding transcatheter heart valves (SE-THVs) Background: BPD is commonly used to optimize valve expansion and reduce paravalvular leakage (PVL) after transcatheter aortic val...
BACKGROUND: The shear stress distribution assessment can provide useful insights for the hemodynamic performance of the implanted stent/scaffold. Our aim was to investigate the effect of a novel bioresorbable scaffold, Mirage on local hemodynamics in animal models. METHOD: The main epicardial coronary ar...
