congenital tricuspid malformation anomaly of the tricuspid valve chordae https://github.com/monarch-initiative/mondo/issues/6740 https://github.com/monarch-initiative/mondo/issues/6876 https://www.malacards.org/card/congenital_anomaly_of_the_tricuspid_valve_chordae MEDGEN:757566 Orphanet:99055 GARD:0019623 Anomaly of the tricuspid valve chordae is 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.
