Prolapse of the intermediate posterior mitral valve scallop (P2) shown in a long axis view of A) a 2D transthoracic echocardiogram, B) a 2D transesophageal echocardiogram (TEE) with C) associated severe, eccentric, anteriorly directed mitral regurgitation, and in a D) 3D TEE surgical view. 2D, two-dimensional; 3D, three-dimensional; AO, aorta; LV, left ventricle; and RV, right ventricle.

Schematic of normal mitral valve histology. ECM, extracellular matrix; GAG, glycosaminoglycans; VEC, valvular endothelial cells; VIC, valvular interstitial cells. Adapted from reference 66.
Figure 4
Figure 4
Two-dimensional parasternal long axis images of posteriorly coapting leaflets (anterior leaflet [AL]; posterior leaflet [PL]) in a normal individual A) versus increased coaptation height and an elongated posterior leaflet in an individual with ‘Abnormal Anterior Coaptation’ or AAC features B) and in a patient with bileaflet mitral valve prolapse (MVP) into the left atrium (LA) C). Schematics D) showing projections of anterior (A) and posterior (P) leaflets onto the mitral annular diameter (D). C indicates the coaptation height relative to the annulus and is calculated as P/D or C/LVID. AO, aorta; LV, left ventricle; LVID, left ventricular internal diameter; and RV, right ventricle.

Figure 5
Proposed temporal spectrum of mitral valve prolapse (MVP) progression with potential interventions/non-surgical therapies depending on progression stage (bottom section). MV, mitral valve; MSD, minimal systolic displacement; A, P, projections of anterior and posterior leaflets onto the mitral annulus; C; mitral leaflet coaptation height; MR, mitral regurgitation; TGF, transforming growth factor.
