Sonographic images of a 24-gestational-week fetus diagnosed with tricuspid dysplasia. The 4CV was considered to be normal by sonographers under Protocol A because they did not find a thickened tricuspid valve (a). In fact, the RA was a little large in size according to careful observation. Also, the thickened tricuspid valves could be detected after careful scan (b). Color Doppler made it quite easy to detect tricuspid regurgitation, which would direct attention to valvular structural anomalies (c). DAO, descending aorta; LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle; S, spine; TR, tricuspid regurgitation; TV, tricuspid valve. The arrows indicate the thickened valves
