ABSTRACT
Objective:To explore the value of current indications for fetal pulmonary valvuloplasty (FPV) by summarizing the postnatal diagnosis, treatment, and prognosis of fetuses with pulmonary atresia with intact ventricular septum (PA/IVS) and right ventricular hypoplasia (RVH).Methods:This prospective study was conducted at the Heart Center of Women and Children's Hospital, Qingdao University from September 2018 to March 2021, which included pregnant women who were (1) with fetal PA/IVS and RVH; (2) unable to receive FPV due to fetal position or gestational age despite the indications; (3) given integrated pre- and postnatal management. Prenatal fetal echocardiography assessment, postnatal diagnosis, treatment, and follow-up were summarized using Wilcoxon matched-pair signed-rank test.Results:A total of 35 singleton pregnant women were diagnosed with fetal PA/IVS and RVH by ultrasonic cardiogram and admitted during the study period. Among the 28 fetuses meeting the FPV indications, 18 underwent FPV, while the other 10 did not due to inappropriate fetal position or gestational age. After excluding four terminated pregnancies, the rest six cases were enrolled. The median gestational age at the initial prenatal fetal echocardiography diagnosis was 28.9 weeks (28.3-30.4 weeks). Compared with the initial evaluation, the fetal right ventricular to left ventricular length/diameter ratio [0.8 (0.6-0.9) vs 0.6 (0.5-0.8)] and tricuspid regurgitation velocity [4.7 m/s (3.2-5.1 m/s) vs 4.1 m/s (3.3-4.8 m/s)] were increased, while tricuspid valve Z value [-0.8(-1.6-0.8) vs 0.4 (-0.3-1.9)] and single-ventricular predictive score [0.5 (0.0-2.0) vs 2.0 (1.0-3.0)] were decreased when re-evaluated six weeks later ( T were-2.21, 2.00,-2.20, and 2.00; all P<0.05). All of the six fetuses were born alive with a median gestational age of 38.9 weeks (37.3-40.1 weeks). The median weight was 3 425 g (3 100-4 160) g after being transferred to cardiac intensive care unit. The median age was 12.5 d (0.0-20.0 d) at the first surgical intervention. The median follow-up duration was 15 months (11.8-18.5 months). At initial diagnosis, the single-ventricular predictive score was 1-2 points in four fetuses, and =3 points in two fetuses. There was no death during follow-up. Four patients achieved anatomical biventricular circulation, one achieved clinical biventricular circulation, and one still needed further follow-up, with single-ventricular predictive score at initial diagnosis of 1-3, 3, and 2 points, respectively. Conclusions:The prognosis is good in fetuses with PA/IVS and RVH who have FPV indications but do not receive intrauterine intervention, which suggests that the current FPV indications may be too broad, and a more suitable FPV indication need to be further explored given the difficulty of implementing FPV.
