Findings

No curated finding names accessory tricuspid valve tissue yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

Accessory tricuspid valve tissue is a rare, congenital, atrioventricular valve malformation characterized by fixed or mobile accessory tissue on the tricuspid valve, usually associated with other complex congenital heart anomalies (atrial septal defect, ventricular septal defect, transposition of great arteries, tetralogy Fallot). It may present clinically with systolic murmur, dyspnea, cyanosis, depending also on accompanying congenital heart anomaly.
