Key result
Ring annuloplasty successfully repairs congenital mitral insufficiency from posterior leaflet hypoplasia.
Why the study?
Congenital mitral insufficiency caused by hypoplasia of the posterior leaflet is a rare condition with limited reported cases.
Case Report (n=1)
Ring annuloplasty can successfully repair congenital mitral insufficiency caused by hypoplasia of the posterior leaflet.
Ring annuloplasty may be feasible for this rare congenital mitral lesion; hypothesis-generating from single-case evidence.
A rare case of congenital mitral insufficiency characterized by the hypoplasia of the posterior leaflet is reported. At operation, the mitral valve was successfully repaired by a ring annuloplasty, which created a satisfactory surface of coaptation between the anterior leaflet and the bulky posterior muscular structure. The presence of this posterior muscular structure represents a developmental arrest at the stage of conversion from muscular chordae and leaflets to thin connective structures.
