Clinical implementation of first trimester screening for congenital heart defects. Prenat Diagn 2024; 44:688-697. [PMID: 38738737 DOI: 10.1002/pd.6584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 04/07/2024] [Accepted: 04/27/2024] [Indexed: 05/14/2024]
Abstract
OBJECTIVE To examine the feasibility and performance of implementing a standardized fetal cardiac scan at the time of a routine first-trimester ultrasound scan. METHOD A retrospective, single-center study in an unselected population between March 2021 and July 2022. A standardized cardiac scan protocol consisting of a four-chamber and 3-vessel trachea view with color Doppler was implemented as part of the routine first-trimester scan. Sonographers were asked to categorize the fetal heart anatomy. Data were stratified into two groups based on the possibility of evaluating the fetal heart. The influence of maternal and fetal characteristics and the detection of major congenital heart disease were investigated. RESULTS A total of 5083 fetuses were included. The fetal heart evaluation was completed in 84.9%. The proportion of successful scans increased throughout the study period from 76% in the first month to 92% in the last month. High maternal body mass index and early gestational age at scan significantly decreased the feasibility. The first-trimester detection of major congenital heart defects was 7/16, of which four cases were identified by the cardiac scan protocol with no false-positive cases. CONCLUSION First-trimester evaluation of the fetal heart by a standardized scan protocol is feasible to implement in daily practice. It can contribute to the earlier detection of congenital heart defects at a very low false positive rate.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2023; 42:2839-2844. [PMID: 37647313 DOI: 10.1002/jum.16323] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/24/2023] [Revised: 08/08/2023] [Accepted: 08/11/2023] [Indexed: 09/01/2023]
Abstract
OBJECTIVES As maternal body mass index (BMI) increases, fetal anatomy ultrasound becomes more challenging, less sensitive, and less likely to be complete. We sought to report our experience of incomplete evaluation of anatomy in patients with BMI of 50 kg/m2 or greater. METHODS This is a retrospective cohort of singleton gestations in mothers with BMI of 50 kg/m2 or greater, undergoing anatomy evaluations between 2017 and 2021 at 9 maternal-fetal-medicine sites in Houston, TX. Patient variables and scan results were collected throughout pregnancy to provide a longitudinal assessment of the primary outcome, completion rate (percent of all scans which optimally captured 24 American Institute of Ultrasound in Medicine-recommended images). Secondary outcomes included the rate of optimal capture of each individual structure. RESULTS In total, 293 patients with BMI ≥50 kg/m2 were identified. Only 28% of initial scans were complete, but over the entire pregnancy, a complete anatomic evaluation was achieved in 76% of women, largely due to weekly ultrasounds done for antenatal testing later in pregnancy. Neither BMI, placental location, nor amniotic fluid volume affected completion rate. The most difficult views are the outflow tracts, 4-chamber view, and spine. CONCLUSIONS One quarter of women with BMI of 50 kg/m2 or greater will not have a complete fetal anatomic evaluation by the end of pregnancy, since even basic fetal anatomic views are technically challenging to complete. Solutions deserve further attention, and may include first trimester imaging, transvaginal imaging, and optimization of ultrasound machine settings.

Am J Obstet Gynecol MFM 2023; 5:101143. [PMID: 37669739 DOI: 10.1016/j.ajogmf.2023.101143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 08/14/2023] [Accepted: 08/24/2023] [Indexed: 09/07/2023]
Abstract
BACKGROUND Second-trimester ultrasound is the standard technique for fetal anatomy evaluation in the United States despite international guidelines and literature that suggest that first-trimester timing may be superior in patients with obesity. First-trimester imaging performs well in cohorts of participants with obesity. OBJECTIVE Our aim was to compare the completion rate of a first-trimester fetal anatomy ultrasound scan with that of a second-trimester fetal anatomy ultrasound scan among pregnant people with a body mass index ≥35 kg/m2. STUDY DESIGN This randomized controlled trial enrolled participants with a body mass index ≥35 kg/m2 with a singleton gestation and who presented before 14+0/7 weeks of gestation. Participants were randomized to receive an ultrasound assessment of anatomy at either 12+0/7 to 13+6/7 weeks or at 18+0/7 to 22+6/7 weeks. The primary outcome was completion rate (percentage of scans that optimally imaged all the required fetal structures). Secondary outcomes included the necessity of a transvaginal approach, completion rates for each individual view, number of anomalies identified and missed in each group, scan duration, and patient perspectives. A 1-year pilot sample was analyzed using Bayesian methods for the primary outcome with a neutral prior and frequentist analyses for the remaining outcomes. RESULTS A total of 128 participants were enrolled, and 1 withdrew consent; 62 subjects underwent a first-trimester ultrasound scan and 62 underwent a second-trimester ultrasound scan. A total of 2 participants did not attend the research visits, and 1 sought termination of pregnancy. In the first-trimester group, 66% (41/62) of ultrasound scans were completed in comparison with 53% (33/62) in the second-trimester ultrasound group (Bayesian relative risk, 1.20; 95% credible interval, 0.91-1.73). When compared with a second-trimester scan plus a follow-up ultrasound, a first-trimester ultrasound plus a second-trimester ultrasound was equally successful in completing the anatomy views (76%). First-trimester anatomy ultrasound scans required a transvaginal approach in 63% (39/62) of cases and had a longer duration than a second-trimester ultrasound scan. No anomalies were missed in either group. First-trimester ultrasound participants who responded to a survey described that they were very satisfied with the technique. CONCLUSION In pregnant subjects with a body mass index ≥35 kg/m2, a single first-trimester anatomy ultrasound scan was more likely to obtain all the recommended anatomic views than a single second-trimester ultrasound scan. An evaluation of anatomy at 12+0/7 to 13+6/7 weeks' gestation plus an evaluation at 18+0/7 to 22+6/7 led to complete anatomic evaluation 4 weeks earlier than 2 second trimester scans. Assessment of ultrasound duration in a clinical setting is needed to ensure feasibility outside of a research setting.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2023; 61:577-586. [PMID: 36240512 DOI: 10.1002/uog.26094] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/26/2022] [Revised: 08/28/2022] [Accepted: 09/08/2022] [Indexed: 05/04/2023]
Abstract
OBJECTIVES To report on the early detection of congenital heart disease (CHD) in low- and high-risk populations managed at our hospital; and perform a detailed analysis of false-negative diagnoses, in order to derive possible recommendations on how to reduce their incidence. METHODS This was a retrospective observational study analyzing cases which underwent an ultrasound examination at the end of the first trimester at the Fetal Medicine and Surgery Unit of Gaslini Children's Hospital, Genoa, Italy, in the period January 2015 to December 2021. The study population included both low-risk pregnancies that underwent standard first-trimester combined screening and high-risk ones referred to our unit because of a positive combined test or suspicion of fetal anomalies raised in a regional community hospital. For each case, the following variables were retrieved and analyzed: number of fetuses, maternal body mass index, gestational age at first-trimester screening, whether the pregnancy was low or high risk, nuchal translucency thickness (normal or > 99th centile), type of CHD, associated extracardiac anomalies, karyotype and pregnancy outcome. For low-risk pregnancies, suspicion of CHD was also recorded. In low-risk cases, sonographic cardiac screening comprised evaluation of the four-chamber view (grayscale and color/power Doppler) and three-vessel-and-trachea view (color/power Doppler). High-risk cases underwent early fetal echocardiography. False-negative cases were categorized according to likely cause of the missed diagnosis, as follows: human factor; technical factor; acoustic-window factor. RESULTS Gestational age at ultrasound ranged from 12 + 0 to 13 + 6 weeks (crown-rump length (CRL), 50.1-84.0 mm) in the low-risk group and from 11 + 5 to 13 + 6 weeks (CRL, 45.1-84.0 mm) in the high-risk group. Over the 7-year study period, 7080 pregnancies were evaluated in the first trimester. Of these, 6879 (7167 fetuses) were low-risk and 201 were high-risk cases. In the low-risk group, there were 30 fetuses with CHD (including 15 major and 15 minor CHD), yielding a prevalence of 4.2/1000 (2.1/1000 for major CHD). Nine of the 30 CHD cases were suspected at screening ultrasound (7/15 major CHD). Excluding cases in which the CHD would not be expected to be associated with a modification of the screening views and would therefore not be detectable on screening ultrasound, 7/12 cases of major CHD were detected, corresponding to a sensitivity of 58.3%. Among the 201 high-risk cases, there were 46 fetuses with CHD (including 44 major and two minor CHD), of which 43 were detected, corresponding to a sensitivity for early fetal echocardiography of 93.5%, or 97.7% if the two cases that were unlikely to be detectable on first-trimester screening were excluded. Analysis of the 11 (of 24) false-negative cases that would be expected to be picked up on screening views revealed that human error (image interpretation and/or scanning approach) was involved in all 11 cases and technical factors (excessive color priority (color-balance function) and/or incorrect plane alignment) were present in two. There was impairment of the acoustic window (associated with maternal obesity and/or twin gestation) as a cofactor in five of the 11 cases. CONCLUSIONS The sensitivity for detection of major CHD of early cardiac screening in low-risk pregnancy is under 60%, partly due to the natural history of CHD and, it seems, partly relating to human error and technical issues with image quality. Factors associated with false-negative diagnoses may be categorized into three types: human error, technical factors and acoustic-window impairment. We recommend: appropriate assessment with fetal posterior spine; that sufficient time is spent on assessment of the fetal situs; and that color/power Doppler settings are adapted to the individual case. A lower threshold for referring doubtful cases for early fetal echocardiography should be adopted in cases of maternal obesity and in twin gestation. © 2022 The Authors.

Abstract
Studies have consistently shown a significant increase in the risk of congenital heart defects in the offspring of diabetic mothers compared with those of nondiabetic pregnancies. Evidence points that all types of pregestational diabetes have the capacity of generating cardiac malformations in a more accentuated manner than in gestational diabetes, and there seems to be an increased risk for all congenital heart defects phenotypes in the presence of maternal diabetes. Currently, the application of some therapies is under study in an attempt to reduce the risks inherent to diabetic pregnancies; however, it has not yet been possible to fully prove their effectiveness. The present review aims to better understand the mechanisms that govern the association between pregestational diabetes and congenital heart defects and how maternal diabetes interferes with fetal cardiac development, as there is still a long way to go in the investigation of this complex process.

Abstract
OBJECTIVE To evaluate the ability of standardized early fetal heart assessment (EFHA) that includes the 4-chamber view, outflow tract relationship (OTR), and transverse arches views (TAV) of the great arteries in excluding major congenital heart defects (CHDs) in high-risk populations. METHODS This retrospective study included high-risk pregnancies for CHDs undergoing EFHA at 11-14 weeks of gestation. Risk factors for CHDs were diabetes mellitus, a family history of CHDs, a history of a CHD use of teratogenic medications, seizure disorder, assisted reproductive treatment-conceived pregnancy, presence of at least one of the ultrasound markers: enlarged nuchal translucency (>95th percentile), tricuspid regurgitation, and reversed a-wave in the ductus venosus, presence of an extracardiac or a suspected cardiac anomaly, a high-risk first trimester combined screen result, and multiple pregnancies. EFHA consisted of visualization of 4ChV, OTR, and TAV, with and without power Doppler ultrasound. The primary outcome was the negative predictive value of EFHA in excluding major CHDs. RESULTS EFHA was performed on 1055 fetuses. Of these, 1024 were used for the final analysis. Of these, 94.9% (n = 923) were singleton. The most common indication for EFHA was maternal DM (n = 231, 22.6%). The sensitivity, specificity, false positive, false negative, and accuracy of EFHA were 93.2%, 99.9%, 1.4%, 0.4%, and 99.5% (P < .0001), respectively, in entire included cases. The performance of EFHA was 88%, 99.9%, 1.4%, 0.4%, and 99.5% (P < .0001) respectively when the terminated cases were excluded. CONCLUSION Early fetal heart assessment is feasible for screening for major CHDs in high-risk populations. This approach may be expanded to the general obstetric population.

Abstract
OBJECTIVES To determine the diagnostic accuracy of ultrasound at 11-14 weeks' gestation in the detection of fetal cardiac abnormalities and to evaluate factors that impact the detection rate. METHODS This was a systematic review of studies evaluating the diagnostic accuracy of ultrasound in the detection of fetal cardiac anomalies at 11-14 weeks' gestation, performed by two independent reviewers. An electronic search of four databases (MEDLINE, EMBASE, Web of Science Core Collection and The Cochrane Library) was conducted for studies published between January 1998 and July 2020. Prospective and retrospective studies evaluating pregnancies at any prior level of risk and in any healthcare setting were eligible for inclusion. The reference standard used was the detection of a cardiac abnormality on postnatal or postmortem examination. Data were extracted from the included studies to populate 2 × 2 tables. Meta-analysis was performed using a random-effects model in order to determine the performance of first-trimester ultrasound in the detection of major cardiac abnormalities overall and of individual types of cardiac abnormality. Data were analyzed separately for high-risk and non-high-risk populations. Preplanned secondary analyses were conducted in order to assess factors that may impact screening performance, including the imaging protocol used for cardiac assessment (including the use of color-flow Doppler), ultrasound modality, year of publication and the index of sonographer suspicion at the time of the scan. Risk of bias and quality assessment were undertaken for all included studies using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. RESULTS The electronic search yielded 4108 citations. Following review of titles and abstracts, 223 publications underwent full-text review, of which 63 studies, reporting on 328 262 fetuses, were selected for inclusion in the meta-analysis. In the non-high-risk population (45 studies, 306 872 fetuses), 1445 major cardiac anomalies were identified (prevalence, 0.41% (95% CI, 0.39-0.43%)). Of these, 767 were detected on first-trimester ultrasound examination of the heart and 678 were not detected. First-trimester ultrasound had a pooled sensitivity of 55.80% (95% CI, 45.87-65.50%), specificity of 99.98% (95% CI, 99.97-99.99%) and positive predictive value of 94.85% (95% CI, 91.63-97.32%) in the non-high-risk population. The cases diagnosed in the first trimester represented 63.67% (95% CI, 54.35-72.49%) of all antenatally diagnosed major cardiac abnormalities in the non-high-risk population. In the high-risk population (18 studies, 21 390 fetuses), 480 major cardiac anomalies were identified (prevalence, 1.36% (95% CI, 1.20-1.52%)). Of these, 338 were detected on first-trimester ultrasound examination and 142 were not detected. First-trimester ultrasound had a pooled sensitivity of 67.74% (95% CI, 55.25-79.06%), specificity of 99.75% (95% CI, 99.47-99.92%) and positive predictive value of 94.22% (95% CI, 90.22-97.22%) in the high-risk population. The cases diagnosed in the first trimester represented 79.86% (95% CI, 69.89-88.25%) of all antenatally diagnosed major cardiac abnormalities in the high-risk population. The imaging protocol used for examination was found to have an important impact on screening performance in both populations (P < 0.0001), with a significantly higher detection rate observed in studies using at least one outflow-tract view or color-flow Doppler imaging (both P < 0.0001). Different types of cardiac anomaly were not equally amenable to detection on first-trimester ultrasound. CONCLUSIONS First-trimester ultrasound examination of the fetal heart allows identification of over half of fetuses affected by major cardiac pathology. Future first-trimester screening programs should follow structured anatomical assessment protocols and consider the introduction of outflow-tract views and color-flow Doppler imaging, as this would improve detection rates of fetal cardiac pathology. © 2021 The Authors.

Abstract
PURPOSE The purpose of this study was to assess the impact of the free choice of ultrasound propagation velocity on ultrasound image construction to improve the completion rate and anatomical quality of fetal second-trimester ultrasound examination in obese women. MATERIALS AND METHODS This repeated cross-sectional single-center study retrospectively collected second-trimester ultrasound images of 88 obese women. During the first period, ultrasound examinations were performed in 44 women (mean age, 31.4±5.9 [SD] years; range: 21.1 - 45.3 years) applying only the standard 1540m/s tissue ultrasound velocity (group 1). During the second period, ultrasound examinations were performed in other 44 women (mean age, 31.4±5.1 [SD] years; range: 20.6 - 41.6 years) with the operator free to choose among three available velocity settings (1420m/s, 1480m/s or 1540m/s) for the scanning planes for the morphological images (group 2). All women underwent mid-trimester ultrasound examination at 20 to 24 gestational weeks. Two observers assessed the examinations in both groups for completeness, quality, and duration of fetal ultrasound examinations. RESULTS No differences in age (P>0.99), body mass index (P=0.67), prevalence of previous cesarean delivery (P=0.30) or gestational age at the second-trimester scan (P=0.20) were found between the two groups. The mean cumulative duration of these ultrasound examinations was longer in group 1 than in group 2 (for both the complete (P=0.04) and incomplete (P=0.03) examinations). The quality of the anatomic images according to Salomon's criteria was less often acceptable in group 1 (5/44, 11.4%) than in group 2 (15/44, 34.1%) (P=0.02). CONCLUSION Free choice of ultrasound velocity improves the overall performance of fetal second-trimester ultrasound examinations in obese women.
