Role of Left Atrial Reservoir Strain Rate in Left Atrial Remodeling in Severe Mitral Regurgitation

Abstract

BACKGROUND: Impaired left atrial (LA) reservoir deformation has been found to be associated with poor functional capacity and outcomes in severe chronic mitral regurgitation (MR). Among patients with primary MR (valve incompetence due to mitral valve pathology), we focus on Carpentier II classification (prolapse or flail mitral valve) and aim to investigate determinants for decreased LA reservoir deformation and its impact on LA remodeling in severe MR. METHODS: ) derived from two-dimensional speckle-tracking echocardiography as LA reservoir function. RESULTS: = 0.002). CONCLUSION: are at a higher risk of its deterioration.
