In this article, we will first review normal mitral valve anatomy, highlighting the individual structure and function of each component of the mitral valve apparatus. We will then discuss the approach to classification of mitral valve disease, including the classic Carpentier approach as well as ...
The mitral valve (MV) apparatus is a dynamic structure that has complex interactions with surrounding anatomy. Disruption of any component of the apparatus or surrounding anatomy can lead to mitral valve regurgitation (MR) (1). MR is the most common valvular heart disorder (2). The incidence ...

1. Mitral Valve Anatomy and Mitral Valve Regurgitation The mitral valve apparatus comprises four main components: mitral valve leaflets (anterior and posterior), mitral annulus, chordae tendineae and papillary muscles. Normal mitral valve function allows unidirectional blood flow from the left atrium (...
In mitral valve prolapse, the mitral apparatus (valve leaflets and chordae) becomes affected by a process called myxomatous degeneration. In myxomatous degeneration, the structural protein collagen forms abnormally and causes thickening, enlargement, and redundancy of the leaflets and chordae. Blood no...

A mitral heart valve annuloplasty ring having a posterior bow that conforms to an abnormal posterior aspect of the mitral annulus. The ring may be generally oval having a major axis
Anatomy The surgicalanatomyof the mitral valve is shown inFigure 47-7. The leaflets are divided into eight segments. The posterior leaflet is divided into three segments (P1, P2, P3) on the basis of anatomically distinct scallops. Each anterior leaflet segment (A1, A2, and A3) is defined ...
