Echocardiographic evaluation of a patient with corrected transposition of the great vessels and Ebstein's anomaly revealed a delayed mitral to tricuspid valve closure interval of 68 milliseconds.
Case Report (n=1)
In a patient with corrected transposition of the great vessels and Ebstein's anomaly of the systemic tricuspid valve, the mitral to tricuspid valve closure interval was significantly delayed (68 ms), similar to typical Ebstein's anomaly.

May signal AV dyssynchrony in corrected transposition with Ebstein's; hypothesis-generating and requires prospective validation.
A case is reported concerning echocardiographic findings in a patient with congenital corrected transposition of the great vessels and Ebstein's anomaly of the tricuspid valve. This presented an unusual opportunity to study atrioventricular valve closure in a patient in whom the Ebstein's malformation involved the systemic atrioventricular valve. The mitral to tricuspid valve closure interval was 68 milliseconds and represented significant delay in tricuspid valve closure. This closure interval is similar to closure intervals previously reported for patients with Ebstein's anomaly without ventricular inversion.

Henry et al. (1979) conducted a case report in Congenital corrected transposition of the great vessels and Ebstein's anomaly of the tricuspid valve (n=1). Echocardiography was evaluated on Mitral to tricuspid valve closure interval. Echocardiographic evaluation of a patient with corrected transposition of the great vessels and Ebstein's anomaly revealed a delayed mitral to tricuspid valve closure interval of 68 milliseconds.
