Patients whose delivery was complicated by shoulder dystocia and who underwent fetal MRI in the third trimester were included in the case group. Patients without shoulder dystocia who were delivered normally and who also underwent fetal MRI in the third trimester were included in the control group. Cases of multiple pregnancy, planned or emergency Cesarean delivery, fetal malformation or those with incomplete MRI examination were excluded. The case group was matched with the control group in a 1:2 ratio according to maternal age, maternal body mass index, gestational diabetes mellitus, diabetes mellitus Type 1 or 2, gestational age at MRI examination, gestational age at birth and birth weight. Shoulder dystocia was defined as per the Royal College of Obstetricians and Gynecologists and significant shoulder dystocia was defined as shoulder dystocia that was not resolved by the McRoberts' maneuver or suprapubic pressure. The following fetal and maternal measurements were quantified on MRI in both groups by two readers (one experienced and one inexperienced physician) who were blinded to the obstetric outcomes: fetal body volume (FBV), shoulder skin-to-skin distance, interhumeral distance, biparietal diameter (BPD), head circumference, obstetric conjugate (OC), sagittal outlet diameter (SOD), coccygeal pelvic outlet (CPO) and maximal transverse diameter (MTD). A stepwise backward logistic regression that included all measurements was performed. The inter-rater reliability of the measurements was estimated using interclass correlation coefficient (ICC).

However, there are limited data on the type and frequency of in-utero cardiac changes seen on fetal echocardiograms (FEs) based on the type of single-ventricle lesion. We aimed to evaluate the utility of serial FEs in detecting cardiac changes during gestation and how these changes impact postnatal management.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;We performed a retrospective review of all FEs for fetuses diagnosed with a single-ventricle lesion at the Children's Healthcare of Atlanta, between January 2012 and January 2023. All patients included in the study had two or more FEs and were evaluated for in-utero cardiac changes based on eight cardiac categories: atrioventricular (AV) valve regurgitation; systemic ventricular dysfunction; ductus arteriosus flow; atrial-level restriction; umbilical artery Doppler pattern; umbilical vein Doppler pattern; evidence of hydrops; and evidence of arrhythmias. All in-utero cardiac changes were classified into three categories: improving, worsening or critical. Any changes noted on serial FEs that altered the fetal cardiac diagnosis were also recorded. Fisher's exact test was used to determine whether the proportion of fetuses with in-utero cardiac changes differed significantly between different segmental findings and single-ventricle lesion subtype.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;A total of 721 FEs were performed for 248 patients over the 11-year study period. The majority of fetuses had hypoplastic left heart syndrome (HLHS) (63.7%) and most changes were seen in the third trimester (median gestational age, 29.3 (range, 17.4-38.4) weeks). In-utero cardiac changes observed on serial FEs were reported in 38 (15.3%) fetuses, with a total of 42 changes noted throughout the study period. However, only eight (3.2%) fetuses had a critical change that impacted perinatal management. All eight fetuses had HLHS, of which the majority developed hydrops (4/8) or atrial-level restriction (3/8). In addition, there were 34 non-critical changes seen in 30 (12.1%) fetuses, largely in the form of intermittent premature atrial contractions, AV valve regurgitation or ventricular dysfunction. There were 12 (2.5%) follow-up FEs that resulted in a change to the fetal cardiac diagnosis, confirmed by postnatal echocardiography.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;In fetuses with single-ventricle lesions, there was a low rate of in-utero cardiac changes that led to alterations in perinatal management. However, fetuses with HLHS were most likely to develop critical changes affecting delivery-room management, often in the form of atrial-level restriction and/or evolving hydrops. It is important to consider these factors when considering the timing of visits for families who face a prenatal diagnosis of a single-ventricle lesion. © 2025 International Society of Ultrasound in Obstetrics and Gynecolo","PeriodicalId":23454,"journal":{"name":"Ultrasound in Obstetrics & Gynecology","volume":" ","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As part of combined first-trimester screening, a routine blood sample was collected at 8-14 weeks' gestation and PAPP-A was measured. Excess serum was stored at -80°C and analyzed for PlGF in batches after delivery. Most women in the PRESIDE study had an extra blood sample collected at the time of the first-trimester scan at 11-14 weeks, which was also analyzed for PlGF and PAPP-A in batches after all the participants had delivered. Screening performance was assessed in terms of the detection rate at a 10% screen-positive rate (SPR) for a combination of PAPP-A or PlGF with maternal factors alone and for a combination of each of these biomarkers with maternal factors, mean arterial pressure (MAP) and uterine artery pulsatility index (UtA-PI).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The study population comprised 8386 women who had a routine combined first-trimester aneuploidy screening blood sample collected at 8-14 weeks' gestation. In pregnancies that developed preterm PE, the median PAPP-A multiples of the median from routine blood samples were 0.78 (95% CI, 0.67-0.90) before 10 weeks, 0.80 (95% CI, 0.58-1.10) at 10 weeks and 0.64 (95% CI, 0.53-0.78) at 11-14 weeks. In women with samples collected before 10 weeks, there was no significant improvement in the detection rate of preterm PE when PAPP-A or PlGF was combined with maternal factors alone or when combined with maternal factors, MAP and UtA-PI. In routine samples collected at or after 10 weeks, PAPP-A only increased the detection rate of preterm PE slightly.

When PlGF collected from the PRESIDE sample at 11-14 weeks was combined with maternal factors, MAP and UtA-PI, there was an increase in the detection rate from 50.9% (95% CI, 37.1-64.6%) to 67.3% (95% CI, 53.3-79.3%), i.e. an increase of 16.4% (95% CI, 5.6-29.0%) at a 10% SPR.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;PAPP-A has limited value in first-trimester screening for PE, whereas PlGF adds significantly to the detection rate of preterm PE at 10-14 weeks' gestation. © 202","PeriodicalId":23454,"journal":{"name":"Ultrasound in Obstetrics & Gynecology","volume":" ","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143701313","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
