Objective To discuss the worthiness of real-time three-dimensional echocardiography in researching normal fetal heart ventricle growth and systolic function. Methods End-systolic volume(EDV),end-diastolic volume(ESV), struggle volume(SV) and ejection fraction(EF) of 54 normal fetal were acquired from 3-D data by Qlab software. The relation between ventricular growth with pregnant week was analysed and the difference of the volume and systolic function between left ventricle with right ventricle were compared. Results Ventricular volume of normal fetal heart (EDV,ESV,SV) were all increased with the gestational ages,there was linear relativity between them,while EF was not increased with pregnant weeks,there was no linear relativity between them. There was no statistics difference on EDV and ESV between left ventricle and right ventricle, while there was statistics difference on SV, EF between them. Conclusions The image of fetal endocarium could be derived clearly by real-time three-dimensional echocardiography, which help to get fetal heart ventricular volume and to study fetal heart growth and function.

Objective To evaluate the clinical value and safety of angiography and embolization in the treatment of pulmonary sequestration causing massive haemoptysis. Methods Though digital subtraction angiography(DSA), abnormal arteries were demonstrated in 12 cases with massive haemoptysis. All the abnormal arteries were embolized by gelatin sponge plus silk thread sterilized with high temperature and pressure. Results Among 12 cases of the pulmonary sequestration, 26 abnormal arteries were discovered, originating from thoracic aorta and presenting enlargement, twisting and irregular diameter with strands of middle and distal arterial segments associated with abundant vasculature network. There were several arteries supplying the lesion in 11 cases, and massive haemoptysis were stopped after embolization. Follow up for 6 to 18 months, no recurrence and no complication occurred. Conclusion Arterial angiography and embolization with gelatin sponge plus silk thread for treating pulmonary sequestration with massive hemoptysis possesses high clinical efficiency and safety.
