Врожденная аномалия хорд трикуспидального клапана

Определение

A rare, congenital anomaly of the tricuspid subvalvular apparatus characterized by aberrant tendinous chords, which insert at the clear zone of the leaflet instead of its free edge and connect to the endocardium instead of the papillary muscles. Resulting tethering of one or more tricuspid leaflets leads to their impaired mobility and tricuspid regurgitation. Association with other congenital cardiac anomalies has been reported.
