Intermittent symptomatic functional mitral regurgitation illustrated by two cases

Abstract

Functional mitral regurgitation may have different haemodynamic consequences, clinical implications and treatment options, such as surgical or percutaneous interventions or implanting a pacemaker. Here we present two cases with haemodynamically significant intermittent functional mitral regurgitation as the underlying mechanism of heart failure. The cases underline the importance of a high index of suspicion in patients with intermittent heart failure, and a careful analysis of echocardiographic images with simultaneous ECG, in order to delineate systolic and diastolic mitral regurgitation
