Integrated pregnancy and perinatal management of complex fetal congenital heart disease: a preliminary retrospective study.
Article in BMC pregnancy and childbirth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCongenital heart disease (CHD) is the most prevalent congenital abnormality worldwide and is the primary contributor to neonatal mortality. Obstetricians in China continue to face uncertainties about optimal delivery timing, appropriate delivery mode, perinatal interventions, and postnatal surgical outcomes for fetuses with complex CHD.
objectiveTo investigate integrated pregnancy and perinatal management strategies for fetuses diagnosed with complex CHD by prenatal ultrasound in China.
methodsA retrospective analysis was performed on 123 fetuses with complex CHD diagnosed by prenatal ultrasound at Peking University People's Hospital between 2016 and 2023.
resultsThe mean gestational age at ultrasound diagnosis was 23.7 ± 3.4 weeks. Among the 123 cases, 11 (8.9%) were total anomalous pulmonary venous connection (TAPVC), 14 (11.4%) pulmonary valve abnormalities (PVA), 7 (5.7%) right ventricular double outlet (DORV), 13 (10.6%) aortic arch abnormalities, 69 (56.1%) complete transposition of the great arteries (D-TGA), and 9 (7.3%) other types. Following prenatal counseling, all pregnancies were continued. Among the 72 fetuses undergoing prenatal genetic testing, 9 (9/72) showed chromosomal variants. Fifty-five pregnant women (44.72%) attempted trial of labor, of whom 46 (37.40%) achieved vaginal delivery, including 6 (4.88%) assisted with forceps. Trial of labor failed in 9 cases, requiring cesarean section. In total, 77 pregnancies were delivered by cesarean section, yielding a cesarean rate of 62.6%. The mean gestational age at delivery was 37.9 ± 1.4 weeks, and the mean neonatal birth weight was 3099.0 ± 479.6 g. The mean umbilical arterial blood gas pH was 7.31 ± 0.05. Postnatally, 86 infants (69.9%) received prostaglandin. Average oxygen saturation increased from 72.8 ± 6.0% before alprostadil administration to 80.5 ± 5.0% afterward, a statistically significant improvement (p = 0.000). A total of 114 neonates underwent surgical intervention; 98.2% achieved favorable outcomes, whereas two infants (1.8%) died postoperatively. Approximately 13.0% were anticipated to require secondary surgery.
conclusionPregnancies involving fetuses with complex CHD should avoid preterm birth whenever possible. Complex fetal CHD alone is not an indication for cesarean delivery; the delivery mode should instead be determined by standard obstetric considerations, and individualized management may be adopted according to their opinions and preferences. When both maternal and fetal status remain stable, scheduling delivery at or beyond 39 weeks may be considered. Newborns who present with low postnatal oxygen saturation should receive prostaglandin to keep the ductus arteriosus open, followed by urgent transfer to pediatric cardiac surgery for definitive management. Coordinated, multidisciplinary care supports favorable clinical outcomes.
