Abstract Objective: To analyze spectrum parameters of fetal ductus venosus of complex fetal heart malformations in middle and late pregnancy, and to find out the relationship between different complex fetal heart malformations and DV waveform characteristics. Method: DV waveform and spectrum parameters of complex fetal heart malformations were recorded, followed-up and grouped. Results: In the cases with right ventricular system abnormalities, the S, D, RI, PVIV and S/A increased significantly, while A waves significantly reduced, disappeard or even reversed. In the cases with left ventricular system abnormalities, the S and D increased, while A, RI, PVIV and S/A had no obvious change. The S, D, A, RI, PVIV and S/A in cases with conus arteriosus abnormalities and huge atrioventricular septal defect had no obvious difference. Conclusion: Abnormal DV waveform can be a clue for different types of complex fetal heart malformations.
