Care must be taken to avoid damaging structures inside the left ventricle such as the interventricular septum, and the chordae tendineae.
Dissociation of leaflet and chordae tendineae provides for unrestricted motion of the leaflet (hence flail leaflet).
The chordae tendineae are attached to papillary muscles that cause tension to better hold the valve.
They are anchored to the walls of the ventricles by chordae tendineae, which prevent the valves from inverting.
Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or even the surfaces of intracardiac devices.
The anterior and posterior papillary muscles of the left ventricle attach via chordae tendineae to the mitral valve.
The distinctive valvular abnormality seen with fenfluramine is a thickening of the leaflet and chordae tendineae.
The anterior, posterior, and septal papillary muscles of the right ventricle each attach via chordae tendineae to the tricuspid valve.
