title: 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.
