Intermittent symptomatic functional mitral regurgitation illustrated by two cases

Alper Aydin et al. Cardiovasc J Afr. .

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.

Figure 1.
Transoesophageal echocardiography images demonstrating severe mitral regurgitation (A) during left bundle branch block. The arrow in B shows impaired coaptation of the mitral valve leaflets (LA: left atrium, LV: left ventricle). The tenting area was measured as 7.8 cm2 (C), and the pulmonary artery pressure (D) was elevated to 95 mmHg.

Figure 2.
Transoesophageal echocardiography images demonstrating mild mitral regurgitation (panels A and B) with a 3.9-cm2 tenting area (panel C), and decreased pulmonary artery pressure to 40 mmHg (panel D). (RA: right atrium, RV: right ventricle, Ao: aorta.)

Colour (A) and continuous-flow Doppler (B) images demonstrating diastolic mitral regurgitation. The bold arrows represent diastolic regurgitation; open arrows represent blocked P waves.
