Secondary Tricuspid Regurgitation
Papillary Muscle Displacement
Modern echocardiographic imaging (particularly real-time 3-D)
have observed septal leaflet tethering in patients with
secondary tricuspid regurgitation who have normal pulmonary
artery pressures
Because the two ventricles are i n t e r d e p e n d e n t
at the septum, left ventricular septal dysfunction also causes
dysfunction of the right septal wall, the area of origin of the
small septal papillary muscles (chords) to the septal and
anterior leaflets of the tricuspid valve (antero-septal
comissural gap).
