Prolapse was seen in three, while two showed increased echogenicity of the leaflets. There was no systolic anterior motion of the mitral valve, but mild prolapse of an aortic leaflet was seen. The leaflets of the valve were redundant with prolapse (myxomatous-like) in ten patients (17.8%). Implicated mechanisms for spontaneous closure are again muscular overgrowth, but include prolapse of the leaflets of the aortic valve into the defect. Annular dilatation or abnormalities of leaflets and tension apparatus, notably prolapse, are the common cause of incompetence, and again can be congenital or acquired. Three patients had prolapsed leaflets and elongated chords. The degree of prolapse muscles associated with hypoplasia of the leaflet may be overestimated when there is retraction of tissue close to the muscle. The size of the membrane did not correlate with either the presence of right-sided obstruction or with prolapse. All other patients had prolapse of coronary cusp of the aortic valve. Symptoms of incontinence and prolapse may only manifest many years after the initial insult at childbirth. The articulation gap, which facilitates flexibility, may however, allow duct tissue to prolapse into the lumen and obstruct flow. These examples are from corpora and from sources on the web.
