Key result
Secondary mitral regurgitation is a common but frequently ignored feature in heart failure with preserved ejection fraction, where its occurrence and pathogenesis remain poorly understood.
This review highlights the occurrence and pathogenesis of secondary mitral regurgitation in HFpEF, a common but often ignored feature.
Secondary MR remains undercharacterized in HFpEF; leaves open its prevalence, mechanisms, and management.
Secondary mitral regurgitation (MR) has been extensively studied in heart failure due to reduced ejection fraction. In contrast, the occurrence and the pathogenesis of secondary MR are much less known in heart failure with preserved ejection fraction (HFpEF). The present review aimed at describing this common but ignored feature of HFpEF.
