[Diagnosing complicated congenital heart disease with two-dimensional echocardiography and three-segment concept].
OBJECTIVE
To apply three-segment heart anatomy concept to two-dimensional echocardiography (2DE) in the diagnosis of complicated congenital heart disease (CHD).


METHODS
920 cases of CHD were diagnosed with 2DE and three-segment heart anatomy concept. 822 out of the 920 cases underwent angiocardiography, and 584 cases were confirmed by operation.


RESULTS
According to three-segment heart anatomy concept of atrial position, 855 cases were situs solitus (including 89 cases of left superior vena cava and 31 cases of complete anomalous pulmonary venous drainage), 53 cases were situs inversus, and 12 cases were situs ambigus. As to atrial-ventricular valve, 747 cases were both opening, 112 cases had one-side atresia, and 61 cases had one together valve; As to ventricle position, 606 cases were dextro-loop, 111 cases had levo-loop, and 203 cases had single ventricle (including 24 cases), As to cor biloculare of great artery relation, 304 cases had normal relation of great arteries, including 35 cases of pulmonary atresia, 219 cases had right-transposition of great arteries, 240 cases had left-transposition of great arteries, 32 cases were mirror to normal, and 25 cases had persistent truncus arteriosus. 823 cases were diagnosed with 2DE, with a total accurate rate of 89.5%.


CONCLUSIONS
Applying three-segment heart anatomy concept to 2DE to diagnose complicated CHD and analyzing the heart segment by segment will make the diagnosis simple and systematic, providing a concise basis for heart surgeries.
