Key result
Tricuspid insufficiency and additional anomalies correlate with functional class, while apical displacement lacks predictive value.

Do echocardiographic parameters correlate with functional class in patients with Ebstein's anomaly?
In Ebstein's anomaly, functional class correlates with tricuspid insufficiency and associated anomalies rather than the degree of apical displacement or delayed closure time.

Tricuspid insufficiency may guide functional assessment in Ebstein's anomaly; leaves open the predictive role of apical displacement in prospective studies.
In 23 patients with Ebstein's anomaly of the tricuspid valve, the functional class of the patients has been related to the echocardiographic parameters generally used to diagnose this disorder. These are the extent of apical displacement of the tricuspid valve and the delay in tricuspid valve closure time related to that of the mitral valve. In addition, the functional class of the patients has also been evaluated in relation to the severity of tricuspid valve insufficiency and to the presence or absence of associated cardiac abnormalities. The study revealed that the echocardiographic parameters i.e. the degree of apical displacement of the tricuspid valve and the delayed closure time of the tricuspid valve have no predictive value for the patient's clinical condition. On the other hand, both tricuspid valve insufficiency and the presence of additional anomalies have a direct correlation with the well-being of the patient.

Gussenhoven et al. (1984) conducted an observational in Ebstein's anomaly of the tricuspid valve (n=23). Echocardiographic parameters (apical displacement, delayed closure time) was evaluated on Functional class / clinical condition. Echocardiographic parameters of apical displacement and delayed closure time had no predictive value for functional class, whereas tricuspid insufficiency and additional anomalies correlated directly.
