Trans-sections from the chordae tendineae, papillary muscle, mitral valve, and near-apex of the LV were subject to morphological assessment.
The aortic valve, tricuspid chordae tendineae, atrioventricular node, conduction bundle are all closely related to the PMVSD.
The classification according to their insertion sites are: first order, the chordae are thin, arise from the papillary muscle, insert on the free edges of the leaflets, and are most common (15).
In this series, compared with FED, BD presented higher incidence of excess P2 height and elongated chordae and lower risk of chordal rupture [Supplementary Table 2].
Satellite lesions with aortic regurgitation often occur on the anterior leaflet of the mitral valve or on the mitral chordae tendinae most commonly when the noncoronary cusp or the adjacent commissure of the aortic valve is involved [6, 8].
The anterior commissure leaflet was resected together with the vegetation and ruptured chordae tendineae, followed by mitral valve replacement.

Atrioventricular (AV) valvular apparatus comprises of AV orifice and its annulus, valvular leaflets, chordae tendineae and papillary muscles.
The most important complication is severe mitral regurgitation due to the myxomatous degeneration or chordae rupture.
The mechanism of regurgitation was due to tethering of the leaflets owing to papillary muscle shortening and annular dilation, as the chordae and leaflets were normal, the jets were central, and there was tip-to-tip coaptation of the leaflets of atrioventricular valves.
