“…Body-weight-corrected data pertaining to these dimensions are as follows: 0.39-0.59 mm/kg for the intercommissural and 0.32-0.48 mm/kg for the aorto-mural diameters, respectively (Fyrenius et al, 2001). However, dimensions are underestimated in vivo by the two-dimensional echocardiography when compared with three-dimensional echocardiography and with magnetic resonance imaging (Anwar et al, 2007). Discordant findings regarding annular dimensions and dynamics appear to be the result of the various and different methods of measurement (Timek and Miller, 2001).…”

As a result of the numerous clinical and surgical data accumulated so far, the classical image of the mitral valve-a bicuspid valve, with two leaflets and two papillary muscles-undergoes significant modifications. The valve, included into the larger concept of the mitral valvular complex unveils numerous important valences and characteristics, among which, some represent newer concepts, of clinical and surgical significance: the valvular complex is a subtle and finely-tuned system of elements acting in a coordinated manner; the mitral valve is an active valve and not a mere passive flap bordering the atrioventricular junction. Not least, the mitral valve contributes to the make up and function of the left ventricular outflow tract. The anatomical and functional interdependence between the mitral valve and the left ventricular myocardium is evident not only following their particularities of vascularization but also it is reflected in morbid states such as ischemic cardiac disease and dilated cardiomyopathy. All the new concepts and ideas, ask for a more profound study of the clinical anatomy of the mitral valve, underscoring the importance of a pertinent dialogue between specialists and by using a more appropriate and unitary terminology.

Mitral regurgitation (MR) poses a significant clinical burden in the adult population, which is expected to increase even more with the ever prolonging life expectancies in developed countries. New technology has brought MR, once exclusively the arena of cardiac surgeons, to the attention of interventional cardiologists. A variety of device-oriented transcatheter strategies have evolved in recent years. A comprehensive understanding of mitral valvular anatomy is crucial for the selection of patients, the implementation of devices, and further refinements of these transcatheter techniques if they are eventually to produce procedural and clinical success. The aim of this review is to elucidate the morphology of the mitral valvular complex, integrating key anatomical features into the developing transcatheter options for the treatment of MR.

“…The mitral annulus (MA) is a vital component of the mitral valve apparatus and dilatation of the MA is one of the main mechanisms of mitral regurgitation . However, like the LVOT the MA is not circular in shape but rather oval or D‐shaped and different cross sections result in different dimensions . An xPlane from a correctly orientated apical two‐chamber view in which the mitral valve scallops P3, A2, P1 and both papillary muscle are intersected symmetrically will allow a measurement of the major (primary image) and minor (secondary image) axis diameters of the mitral valve annulus (Fig.…”
