1. Conclusion To evaluate AEF with Doppler echocardiograph is noninvasive and easy and accurately.

2. Real-time three-dimensional echocardiograph(RT-3DE)was a new technology and a new breakthrough in the field of echocardiographicy.

3. Conclusions Echocardiograph can provide important evidences in detecting special shaped ventricular septal defect, which gives more rationales for selecting operation motheds.

4. Methods: Twenty-eight patients with cardiac space-occupying lesions, determined by surgical operation and pathology, undertook two-dimensional echocardiograph (2DE) and RT3DE.

5. Methods Cardiac structures and functional parameters of 45 cases were detected with color Doppler echocardiograph and the results underwent linear correlation analyses.
