Prevalence and Prognostic Significance of Functional Mitral and Tricuspid Regurgitation Despite Preserved Left Ventricular Ejection Fraction in Atrial Fibrillation Patients

Abstract

Significant functional MR and TR are seen in a substantial proportion of patients with longstanding AF, despite preserved LVEF. This MR/TR combination predicts poor outcome for AF patients, who may have to be treated more intensively.
