History

 * Presentation depends greatly on the degree of apical displacement of the tricuspid valve leaflet as well as the degree of dysfunction of the tricuspid valve. If the tricuspid valve is severely deformed, fetal hydrops may occur. If the valve is functioning, patients may remain symptom free for many years.


 * The majority of patients have dyspnea and cyanosis (40%) but some may be asymptomatic.


 * Palpitations may occur secondary to SVTs (supraventricular tachycardia) and WPW (Wolff-Parkinson-White syndrome) (8%).


 * Growth and development are normal.
