Microvascular Dysfunction Is Associated With Impaired Myocardial Work in Obstru...
Garcia Brás, P; Aguiar Rosa, S; Cardoso, I; Branco, L; Galrinho, A; Valentim Gonçalves, A; Thomas, B; Viegas, JM; Fiarresga, A; Branco, G; Pereira, RBackground Two-dimensional speckle tracking echocardiography has been shown to correlate with microvascular dysfunction, a hallmark of hypertrophic cardiomyopathy (HCM). We hypothesized that there is an association between myocardial work and left ventricular ischemia, with incremental value to global longitudinal strain, in patients with HCM. Methods and Results We performed a prospective assessment of patient...
Index of Microcirculatory Resistance in the Assessment of Coronary Microvascula...
Aguiar Rosa, S; Mota Carmo, M; Rocha Lopes, L; Oliveira, E; Thomas, B; Baquero, L; Cruz Ferreira, R; Fiarresga, AIntroduction and objectives: Coronary microvascular dysfunction (CMD) is one of the most important pathophysiological features in hypertrophic cardiomyopathy (HCM). The index of microcirculatory resistance (IMR) is an invasive method to assess the coronary microcirculation. The aim was to assess CMD in patients with HCM by IMR. Methods: Adult patients with HCM without epicardial coronary artery disease underwen...
Blunted Coronary Flow Velocity Reserve is Associated With Impairment in Systoli...
Aguiar Rosa, S; Rocha Lopes, L; Branco, L; Galrinho, A; Fiarresga, A; Thomas, B; Brás, P; Gonçalves, A; Cardoso, I; Papoila, A; Alves, M; Rio, PBackground Coronary microvascular dysfunction constitutes an important pathophysiological feature in hypertrophic cardiomyopathy (HCM). We aimed to assess the association between impaired coronary flow velocity reserve (CFVR) and ventricular systolic function and functional capacity. Methods Eighty-three patients with HCM were enrolled in this prospective cohort study. Patients underwent echocardiogram to evalu...
Associations Between Perfusion Defects, Tissue Changes and Myocardial Deformati...
Brás, P; Aguiar Rosa, S; Thomas, B; Fiarresga, A; Cardoso, I; Pereira, R; Branco, G; Cruz, I; Baquero, L; Cruz Ferreira, R; Mota Carmo, MBackground: Microvascular dysfunction is an often overlooked feature of hypertrophic cardiomyopathy (HCM). Our aim was to assess the association between microvascular dysfunction, wall thickness, tissue characteristics and myocardial deformation in HCM patients, by analyzing individual myocardial segments. Methods: Prospective assessment including cardiac magnetic resonance to assess wall thickness, T1 and T2 m...
The Impact of Ischemia Assessed by Magnetic Resonance on Functional, Arrhythmic...
Aguiar Rosa, S; Thomas, B; Fiarresga, A; Papoila, AL; Alves, M; Pereira, R; Branco, G; Cruz, I; Rio, P; Baquero, L; Cruz Ferreira, R; Mota Carmo, MAims: The aim of the study is to investigate the association between the degree of ischemia due to coronary microvascular dysfunction (CMD) and the left ventricular (LV) tissue characteristics, systolic performance, and clinical manifestations in hypertrophic cardiomyopathy (HCM). Methods and Results: This prospective study enrolled 75 patients with HCM without obstructive epicardial coronary artery disease. Ea...
Documento de Consenso Sobre Codificação de Exames de Ressonância Magnética Card...
Ferreira, AM; Almeida, AG; Oliveira, L; Bettencourt, N; Marques, H; Matos, P; Abecasis, J; Abreu, J; Alpendurada, F; Botelho, A; Campos, P; Castela, SUm dos obstáculos a uma utilização mais frequente e apropriada da ressonância magnética cardíaca (RMC) em Portugal tem sido a ausência de códigos específicos que descrevam adequadamente os exames tal como são efetuados actualmente. Este documento de consenso fornece recomendações para a atualização e uniformização dos códigos empregues na RMC. São igualmente feitas recomendações quanto às técnicas e códigos a u...
