ABSTRACT
PURPOSE:
To analyze the influence of RV dysfunction evaluated by Free-angle M-mode (FAM) TAPSE Z-score on retrograde ductus arteriosus flow (RDAF) in fetuses with Ebstein anomaly (EA).METHODS:
A retrospective cohort study of 30 EA and 60 normal fetuses were enrolled. The EA group was divided into two groups with RDAF (EA-RDAF group) and without RDAF (EA-NRDAF group). FAM was used to measure TAPSE of EA and normal fetuses, and Z-scores were calculated. The differences of FAM-TAPSE Z-score, gestational week (GW), maternal age (MA), and mitral valve-tricuspid valve distance (MTD) between three groups were compared. The correlation and binary logistic regression between FAM-TAPSE Z-score, GW, MA, MTD, and RDAF were analyzed.RESULTS:
FAM-TAPSE Z-score was significantly lower in EA-RDAF group compared to other groups (p < 0.05). FAM-TAPSE Z-score, GW, and MA were negatively correlated with RDAF (p < 0.05), but no correlation was found between TR, MDT, and RDAF (p > 0.05). Multivariate logistic regression showed that FAM-TAPSE Z-score was an independent influencing factor for RDAF (OR = 0.102, p < 0.05).CONCLUSION:
RV dysfunction is an independent factor leading to RDAF in EA fetus, which provides a feasible theoretical basis for further study on improvement of RV function through intrauterine treatment to delay and prevent the RDAF, to avoid death cycle and improve live-birth rate.Palabras clave
