Imaging assessment of mitral and aortic regurgitation: current state of the art




Learning objectives

  • To understand the advantages and disadvantages of imaging techniques in identifying aetiology and mechanisms of mitral and aortic regurgitation.

  • To understand the key echocardiographic methods of quantifying severity of mitral regurgitation (MR) and aortic regurgitation (AR), and their advantages and limitations.

  • To be aware of the relative advantages and disadvantages of cardiac magnetic resonance in quantifying severity of MR and AR.

  • Introduction

    Valvular heart disease (VHD) affects 1 in 50 of the general population and 1 in 3 of the over 65s, and is associated with increased morbidity and premature mortality.1 Among adults presenting to hospital with severe VHD, mitral regurgitation (MR: 21.3%) is the second and aortic regurgitation (AR: 5.3%) is the third most common valve lesion after aortic stenosis (41.2%).2 The predominance of MR above AR is also found in community-based studies, although it...
