Abstract Background Functional mitral regurgitation (FMR) is associated with dilated cardiomyopathy (DC), heart failure (HF) and worsening left atrial function (LAF). Patients with DC and FMR may present left atrial dysfunction resulting from both ventricular dysfunction and valve disease, but it is unknown whether the presence of valve disease will lead to greater LAF impairment. Objective This study aimed to evaluate the relationship between LAF parameters and FMR degree in patients with DC. Methods This cross-sectional observational study included 214 […]

Introduction Muscular dystrophies (MD) are a group of heterogeneous diseases genetically determined and characterized by progressive muscle atrophy and weakness. Mutations in genes encoding muscle fiber proteins lead to the development of MD. MD types vary by deficient protein, each with its natural history and characteristic clinical presentation. As with other clinical aspects, cardiac involvement is also quite variable. , This article will review the most important aspects of the clinical-echocardiographic follow-up of MD types frequently associated with cardiomyopathies, including […]

Abstract Background: Heart failure with reduced ejection fraction is responsible for half of heart failure cases worldwide and implicates in substantial morbidity and mortality. However, even with clinical history and physical examination associated with conventional complementary exams, many patients remain without etiological diagnosis. Cardiac magnetic resonance has offered the possibility to clarify a variable proportion of these cases. Objective: To verify how much cardiac magnetic resonance contributes to etiologic diagnosis of heart failure with left ventricular ejection fraction
