The repair of mitral insufficiency associated with ruptured chordae tendinae.
The problem of mitral insufficiency caused by accessory chordae tendineae in persistent common atrioventricular canal.
It may be considered that reconstruction of chordae is an important factor in improving the results of surgical repair to the prolapsed leaflet.
The surgical procedure consisted of subtotal resection of the anterior and posterior leaflets whereby their free margins with the insertion sites of the chordae were left untouched.
Elongation of the chordae tendineae often causes rupture, commonly to the chordae attached to the posterior leaflet.
Together, the papillary muscles and the chordae tendineae are known as the subvalvular apparatus.
The third type, the papillary muscles give origin at their apices to the chordae tendinae which attach to the cusps of the tricuspid valve.
The anterior, posterior, and septal papillary muscles of the right ventricle each attach via chordae tendineae to the tricuspid valve.
