Tricuspid Regurgitation in Heart Diseases in Infants and Children

ABSTRACT

Doppler echocardiography was performed to evaluate the tricuspid regurgitation in 786 infants and children with heart disease. 3 Doppler methods were used. The duration of systolic turbulence of tricuspid regurgitation in thr right atrium was evaluated by continuous wave Doppler method, the distance of systolic turbulence within right atrium from the tricuspid plane, by pulsed Doppler method and the retrograde systolic hepatic vein regurgitation, by color Doppler method. The following results were obtained. 1) Incidence of pan systolic tricuspid regurgitation in each disease were as follows. 68% of ECD, 66% of Ebstein's anomaly, 54% of pulmonary atresia, 50% of arrhythmia, 45% of ASD, 38% of TAPVR, 15% of VSD, 26% of TOF, 12% of PDA, 13% of normal children. 2) In about 90% of children with tricuspid regurgitation, hepatic vein regurgitation was detected by color Doppler echocardiography.
