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 […]
