Abstract
Although fetal cardiac programs are well established in developed countries, establishing an efficient program in low- and middle-income countries (LMICs) is still considered a significant challenge. Substantial obstacles usually face the initiation of fetal cardiac service from scratch in LMICs. The primary structural frame of a successful fetal cardiac program is described in detail, emphasizing the required team members. The potential challenges for starting fetal cardiac services in LMICs include financial, awareness-related, prenatal obstetric screening, sociocultural, psychosocial, and social support factors. These challenges could be solved by addressing these barriers, such as collecting funds for financial support, raising awareness among families and health care providers, telemedicine, building international health partnerships, modifying training protocols for fetal cardiologists and sonographers, and initiating support groups and social services for families with confirmed fetal cardiac disease. Initiating a successful fetal cardiac program requires multi-aspect structural planning. The challenges for program initiation require diverse efforts, from modified training and promoting awareness of care providers and the community to governmental and nonprofit organizations' collaborations for proper building and utilization of program resources.

[PMID: 36609702 DOI: 10.1007/s00404-023-06910-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2022] [Accepted: 01/01/2023] [Indexed: 01/09/2023]
Abstract
PURPOSE The aim of this meta-analysis was to evaluate the risk of chromosomal abnormalities in fetuses with congenital heart disease (CHD). METHODS Four literature databases were searched until 17th January 2022 using the relevant medical subject heading terms, word variants, and keywords for "congenital heart defect, fetal, and chromosomal abnormalities". The prevalence of overall chromosomal abnormality, aneuploidy, 22q11 deletion, other copy number variants (CNVs), and variants of unknown significance (VOUS) was analyzed. RESULTS 45 studies met the inclusion criteria for the analysis. The pooled proportion of overall chromosomal abnormalities, aneuploidy, 22q11 deletion, and other CNVs in fetuses with CHD was 23% (95% CI: 20-26%), 19% (95% CI, 16-22%), 2% (95% CI, 2-3%), and 4% (95% CI, 3-5%), respectively. The incidence of overall chromosomal abnormalities, aneuploidy, and other CNVs in non-isolated CHD was higher than in isolated CHD, with odds ratios of 3.08, 3.45, and 4.02, respectively. The incidence of overall chromosomal abnormalities in septal defects was higher than in conotruncal defects and other defects, with odds ratios of 1.60 and 3.61, respectively. In addition, the pooled proportion of VOUS in CHD was 4%. CONCLUSION CHD is commonly associated with chromosomal abnormalities. If karyotyping or fluorescence in situ hybridization is normal, chromosomal microarray should be performed to look for submicroscopic abnormalities, especially in fetuses with non-isolated CHD and septal defects.

Associated factors with parental pregnancy decision-making and use of consultation after a prenatal congenital heart disease diagnosis. Pediatr Neonatol 2023; 64:371-380. [PMID: 36585272 DOI: 10.1016/j.pedneo.2022.07.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 07/12/2022] [Accepted: 07/18/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Prenatal diagnosis of congenital heart disease (CHD) often leads affected families to experience psychological stress. Pediatric cardiology consultation is important in providing parents with sufficient information and reducing their anxiety to make an informed pregnancy decision. Involving a fetal nurse coordinator may optimize fetal anomaly care. Our study aimed to identify factors associated with parental decision-making for choosing to use pediatric cardiology consultations and pregnancy termination. METHODS From September 2017 to December 2018, all fetal CHD cases diagnosed in the second trimester from a primary screening clinic in Taiwan were included (n = 145). Univariate and multivariate logistic regression were performed to analyze maternal, fetal, and medical factors for predictors of parental decisions for consultation use and pregnancy termination. RESULTS Acceptance for fetal nurse coordinator care and pediatric cardiology consultation were 84.8% (n = 123) and 83.4% (n = 121), respectively. Predictors for termination of pregnancy included the following: multiple anomalies (OR: 10.6; 95% CI: 3.6-35.7), chromosomal/genetic abnormalities (OR: 20.2; 95% CI: 3.1-395.8), severe CHDs (OR: 9.8; 95% CI: 4.3-23.4), CHDs that required surgery (OR: 32.4; 95% CI: 11.4-117.8), and physiological single-ventricle (OR: 47.3; 95% CI: 12.4-312.5). Parents who had pediatric cardiology counseling were less likely to terminate the pregnancy (OR: 0.1; 95% CI: 0.0-0.7). Parents with fetal diagnosis having multiple anomalies (OR: 0.2; 95% CI: 0.1-0.7) or chromosomal/genetic abnormalities (OR: 0.1; 95% CI: 0.03-0.9) were less likely to make use of cardiology consultation. Parents who accepted fetal nurse coordinator care were more likely to have pediatric cardiology consultation before pregnancy decision (OR: 149.5, 95% CI: 37.8-821.5). CONCLUSIONS Anomaly complexity appeared to be a strong predictor for termination of pregnancy beyond non-acceptability of prenatal cardiology consultation. Prenatal cardiology counseling may help support the parental decision to continue with the pregnancy. Incorporation of a fetal nurse coordinator care into the multidisciplinary fetal medicine team improved the acceptability of prenatal consultation.

J Perinat Med 2022; 51:477-491. [PMID: 36474319 PMCID: PMC10164033 DOI: 10.1515/jpm-2022-0387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Accepted: 10/15/2022] [Indexed: 12/12/2022]
Abstract
OBJECTIVES Manual and intelligent navigation (i.e. fetal intelligent navigation echocardiography or FINE) by the operator are two methods to obtain standard fetal cardiac views from spatiotemporal image correlation (STIC) volumes. The objective was to compare the performance between manual and intelligent navigation (FINE) of the fetal heart by non-expert sonologists. METHODS In this prospective observational study, ten sonologists underwent formal training on both navigational methods. Subsequently, they were tested on their ability to obtain nine cardiac views from five STIC volumes of normal fetal hearts (19-28 gestational weeks) using such methods. The following parameters were determined for both methods: (1) success rate of obtaining nine cardiac views; (2) mean time to obtain nine cardiac views per sonologist; and (3) maximum number of cardiac views successfully obtained for each STIC volume. RESULTS All fetal cardiac images obtained from 100 STIC volumes (50 for each navigational method) were reviewed by an expert in fetal echocardiography. Compared to manual navigation, FINE was associated with a significantly: (1) higher success rate of obtaining eight (excluding the abdomen view) appropriate cardiac views (92-100% vs. 56-88%; all p<0.05); (2) shorter mean time (minute:seconds) to obtain nine cardiac views (2:11 ± 0:37 vs. 15:49 ± 7:44; p<0.0001); and (3) higher success rate of obtaining all nine cardiac views for a given STIC volume (86 vs. 14%; p<0.001). CONCLUSIONS When performed by non-expert sonologists, intelligent navigation (FINE) had a superior performance compared to manual navigation of the normal fetal heart. Specifically, FINE obtained appropriate fetal cardiac views in 92-100% of cases.

Maximal Reduction of STIC Acquisition Time for Volumetric Assessment of the Fetal Heart—Benefits and Limitations of Semiautomatic Fetal Intelligent Navigation Echocardiography (FINE) Static Mode. J Clin Med 2022; 11:jcm11144062. [PMID: 35887826 PMCID: PMC9320472 DOI: 10.3390/jcm11144062] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 07/09/2022] [Accepted: 07/12/2022] [Indexed: 11/17/2022] Open
Abstract
(1) Objective: To scrutinize the reliability and the clinical value of routinely used fetal intelligent navigation echocardiography (FINE) static mode (5DHeartStatic™) for accelerated semiautomatic volumetric assessment of the normal fetal heart. (2) Methods: In this study, a total of 296 second and third trimester fetuses were examined by targeted ultrasound. Spatiotemporal image correlation (STIC) volumes of the fetal heart were acquired for further volumetric assessment. In addition, all fetal hearts were scanned by a fast acquisition time volume (1 s). The volumes were analyzed using the FINE software. The data were investigated regarding the number of properly reconstructed planes and cardiac axis. (3) Results: A total of 257 volumes were included for final analysis. The mean gestational age (GA) was 23.9 weeks (14.3 to 37.7 weeks). In 96.9 (standard acquisition time, FINE standard mode) and 94.2% (fast acquisition time, FINE static mode) at least seven planes were reconstructed properly (p = 0.0961, not significant). Regarding the overall depiction rate, the standard mode was able to reconstruct 96.9% of the planes properly, whereas the static mode showed 95.2% of the planes (p = 0.0098). Moreover, there was no significant difference between the automatic measurement of the cardiac axis (37.95 + 9.14 vs. 38.00 + 8.92 degrees, p = 0.8827, not significant). (4) Conclusions: Based on our results, the FINE static mode technique is a reliable method. It provides similar information of the cardiac anatomy compared to conventional STIC volumes assessed by the FINE method. The FINE static mode has the potential to minimize the influence of motion artifacts during volume acquisition and might therefore be helpful concerning volumetric cardiac assessment in daily routine.

Abstract
BACKGROUND Examine the effectiveness of prenatal ultrasound diagnostics in the detection of cardiovascular malformations, and their association with polyhydramnios and oligohydramnios. METHODS We examined the fetal ultrasonography and postnatal clinical/fetopathological data of 372 newborns/fetuses over a 7-year period in a tertiary centre. Fetal echocardiography was performed in cases of suspected US findings between 18-32 weeks. During the ultrasound the amniotic fluid amount was measured and the amniotic fluid index (AFI) or largest amniotic fluid pocket was determined. RESULTS Prenatal ultrasonographic results and postnatal/fetopathological diagnosis were fully congruent in 236/372 cases (63.4%), and in 66/372 cases of cardiovascular anomalies (17.7%) the discovery was partial, while in 70/372 cases no fetal cardiovascular anomalies were diagnosed during pregnancy (18.8%) (false negative). Cardiovascular malformations were isolated in 255 cases, in 172 of which (67.5%) the results of prenatal ultrasonography and postnatal diagnostics were fully congruent. In 43 cases (16.9%) the prenatal discovery was partial, and in 40 cases (15.7%) there was no prenatal recognition of the malformation. Cardiovascular abnormalities were found as a part of multiple malformations in 76 cases. In 41 fetuses the cardiovascular malformation was associated with chromosomal abnormalities. Cardiovascular malformations were significantly associated with polyhydramnios. Although in some of the cardiovascular malformations the association rate with polyhydramnios was high (AVSD, double outlet right ventricle, tetralogy of Fallot), we found a moderate association rate (19.7%). The association with oligohydramnios was 8.57%. CONCLUSIONS Echocardiography plays an important role in the prenatal diagnostics. In cases of polyhydramnios and oligohydramnios, fetal echocardiography should be performed.

Abstract
OBJECTIVES We investigated the feasibility of a semiautomatic approach for assessments of the fetal heart (fetal intelligent navigation echocardiography [FINE]) in cases of optimal and unfavorable fetal spine positions. METHODS In this study, a total of 1693 spatiotemporal image correlation volumes of first-, second-, and third-trimester fetuses were evaluated by experts using the FINE approach. The data were analyzed regarding proper reconstruction of the diagnostic cardiac planes depending on the fetal spine position. RESULTS A total of 1531 volumes were included. The volumes were divided into 4 groups depending on the fetal spine position: 5-7 o'clock, 4 + 8 o'clock, 3 + 9 o'clock, and 2 + 10 o'clock. In total, 93.2% of the diagnostic planes were displayed properly. Between 5 and 7 o'clock, 94.9% of the diagnostic planes were displayed properly. The correct depiction rates in the other groups were 92.4% (4 + 8 o'clock; n = 538; P = 0.0027), 88.3% (3 + 9 o'clock; n = 156; P < .0001), and 87.3% (2 + 10 o'clock; n = 41; P = .0139). In total, the highest dropout rates were found in the sagittal planes: ductal arch, 13.9%; aortic arch, 10.5%; and venae cavae, 12.0%. CONCLUSIONS Based on our results, the FINE technique is an effective method, but its feasibility depends on the fetal position. The use of this semiautomatic work flow-based approach supports evaluation of the fetal heart in a standardized manner. Semiautomatic evaluation of the fetal heart might be useful in facilitating the detection of fetal cardiac anomalies.

Abstract
The main objective of this study was to investigate the diagnostic performance of FINE in generating and displaying 3 specific abnormal fetal echocardiography views such as left ventricular outflow tract (LVOT) view, right ventricular outflow tract (RVOT) view, and 3-vessels and trachea (3VT) view in fetuses with double-outlet right ventricle (DORV). In this prospective study, thirty fetuses diagnosed with DORV by fetal echocardiography in the second and third trimesters were enrolled. One or more STIC volume data-sets were collected from the 4-chamber view as initial view for each fetus, one optimal volume per fetus was selected for on-line analysis using FINE, and the diagnosis plane image was optimized using the Virtual Intelligent Sonographer Assistance (VIS-assistance).The visualization rates of 3 specific abnormal fetal echocardiography views of DORV and key diagnostic elements were calculated. One or more STIC volumes (n = 30 total) were obtained in 25 patients. A single STIC volume per patient was analyzed using the FINE method. FINE was able to successfully generate and display 3 specific abnormal fetal echocardiography views. The display rates of the 3 specific abnormal fetal echocardiography views (3VT, LVOT, RVOT) were 84.0%, 76.0% and 84.0%, respectively. By applying intelligent navigation technology to STIC volume data-sets, the FINE method can successfully generate three specific abnormal cardiac fetal echocardiography diagnostic views in fetuses with DORV, the FINE method can be used for screening and remote consultation of fetal DORV.

Abstract
OBJECTIVES To investigate the interobserver and intraobserver variability and corresponding learning curve in a semiautomatic approach for a standardized assessment of the fetal heart (fetal intelligent navigation echocardiography [FINE]). METHODS A total of 30 stored spatiotemporal image correlation volume data sets of second-trimester fetuses were evaluated by 3 physicians with different levels of expertise in fetal echocardiography by using the FINE approach. Data were analyzed regarding the examination time and proper reconstruction of the diagnostic cardiac planes. The completions and numbers of correct depictions of all diagnostic planes were evaluated by a blinded expert (time t0). To determine interobserver and intraobserver variability, the volumes were reassessed after a 4-week training interval (time t1). RESULTS All operators were able to perform the investigation on all 30 volumes. At t0, the interobserver variability between the beginner and both the advanced (P = .0013) and expert (P < .0001) examiners was high. Focusing on intraobserver variability at t1, the beginner showed a marked improvement (P = .0087), whereas in advanced and expert hands, no further improvement regarding proper achievement of all diagnostic planes could be noticed (P > .999; P = .8383). The beginner also showed improvement in the mean investigation time (t0, 82.8 seconds; t1, 73.4 seconds; P = .0895); nevertheless, the advanced and expert examiners were faster in completing the examination (t1, advanced, 20.9 seconds; expert, 28.3 seconds; each P < .0001). CONCLUSIONS Based on our results, the FINE technique is a reliable and easily learned method. The use of this semiautomatic work flow-based approach supports evaluation of the fetal heart in a standardized and time-saving manner. A semiautomatic evaluation of the fetal heart might be useful in facilitating the detection of fetal cardiac anomalies.

Abstract
OBJECTIVE To evaluate the performance of Fetal Intelligent Navigation Echocardiography (FINE) applied to spatiotemporal image correlation (STIC) volume datasets of the normal fetal heart in generating standard fetal echocardiography views. METHODS In this prospective cohort study of patients with normal fetal hearts (19-30 gestational weeks), one or more STIC volume datasets were obtained of the apical four-chamber view. Each STIC volume successfully obtained was evaluated by STICLoop™ to determine its appropriateness before applying the FINE method. Visualization rates for standard fetal echocardiography views using diagnostic planes and/or Virtual Intelligent Sonographer Assistance (VIS-Assistance®) were calculated. RESULTS One or more STIC volumes (total n = 463) were obtained from 246 patients. A single STIC volume per patient was analyzed using the FINE method. In normal cases, FINE was able to generate nine fetal echocardiography views using: (1) diagnostic planes in 76-100% of the cases, (2) VIS-Assistance® in 96-100% of the cases, and (3) a combination of diagnostic planes and/or VIS-Assistance® in 96-100% of the cases. CONCLUSION FINE applied to STIC volumes can successfully generate nine standard fetal echocardiography views in 96-100% of cases in the 2nd and 3rd trimesters. This suggests that the technology can be used as a method of screening for congenital heart disease.

Abstract
OBJECTIVE To evaluate prospectively the performance of Fetal Intelligent Navigation Echocardiography (FINE) applied to spatiotemporal image correlation (STIC) volume datasets of the normal fetal heart. METHODS In all women between 19 and 30 weeks' gestation with a normal fetal heart, an attempt was made to acquire STIC volume datasets of the apical four-chamber view if the following criteria were met: (1) fetal spine located between 5- and 7-o'clock positions; (2) minimal or absent shadowing (including a clearly visible transverse aortic arch); (3) absence of fetal breathing, hiccups, or movement; and (4) adequate image quality. Each STIC volume successfully acquired was evaluated by STICLoop™ to determine its appropriateness before applying the FINE method. Visualization rates of fetal echocardiography views using diagnostic planes and/or Virtual Intelligent Sonographer Assistance (VIS-Assistance®) were calculated. RESULTS One or more STIC volumes (365 in total) were obtained successfully in 72.5% (150/207) of women undergoing ultrasound examination. Of the 365 volumes evaluated by STICLoop, 351 (96.2%) were considered to be appropriate. From the 351 STIC volumes, only one STIC volume per patient (n = 150) was analyzed using the FINE method, and consequently nine fetal echocardiography views were generated in 76-100% of cases using diagnostic planes only, in 98-100% of cases using VIS-Assistance only, and in 98-100% of cases when using a combination of diagnostic planes and/or VIS-Assistance. CONCLUSIONS In women between 19 and 30 weeks' gestation with a normal fetal heart undergoing prospective sonographic examination, STIC volumes can be obtained successfully in 72.5% of cases. The FINE method can be applied to generate nine standard fetal echocardiography views in 98-100% of these cases using a combination of diagnostic planes and/or VIS-Assistance. This suggests that FINE could be implemented in fetal cardiac screening programs. Published 2015. This article is a U.S. Government work and is in the public domain in the USA.

Abstract
OBJECTIVE To describe a novel method (Fetal Intelligent Navigation Echocardiography (FINE)) for visualization of standard fetal echocardiography views from volume datasets obtained with spatiotemporal image correlation (STIC) and application of 'intelligent navigation' technology. METHODS We developed a method to: 1) demonstrate nine cardiac diagnostic planes; and 2) spontaneously navigate the anatomy surrounding each of the nine cardiac diagnostic planes (Virtual Intelligent Sonographer Assistance (VIS-Assistance®)). The method consists of marking seven anatomical structures of the fetal heart. The following echocardiography views are then automatically generated: 1) four chamber; 2) five chamber; 3) left ventricular outflow tract; 4) short-axis view of great vessels/right ventricular outflow tract; 5) three vessels and trachea; 6) abdomen/stomach; 7) ductal arch; 8) aortic arch; and 9) superior and inferior vena cava. The FINE method was tested in a separate set of 50 STIC volumes of normal hearts (18.6-37.2 weeks of gestation), and visualization rates for fetal echocardiography views using diagnostic planes and/or VIS-Assistance® were calculated. To examine the feasibility of identifying abnormal cardiac anatomy, we tested the method in four cases with proven congenital heart defects (coarctation of aorta, tetralogy of Fallot, transposition of great vessels and pulmonary atresia with intact ventricular septum). RESULTS In normal cases, the FINE method was able to generate nine fetal echocardiography views using: 1) diagnostic planes in 78-100% of cases; 2) VIS-Assistance® in 98-100% of cases; and 3) a combination of diagnostic planes and/or VIS-Assistance® in 98-100% of cases. In all four abnormal cases, the FINE method demonstrated evidence of abnormal fetal cardiac anatomy. CONCLUSIONS The FINE method can be used to visualize nine standard fetal echocardiography views in normal hearts by applying 'intelligent navigation' technology to STIC volume datasets. This method can simplify examination of the fetal heart and reduce operator dependency. The observation of abnormal echocardiography views in the diagnostic planes and/or VIS-Assistance® should raise the index of suspicion for congenital heart disease.

Abstract
Background and Objectives We hypothesized that fetal echocardiography (echoCG) is an accurate diagnostic tool reflecting well postnatal echoCG findings and outcomes. Subjects and Methods We reviewed the medical records of 290 pregnant women, including 313 fetuses, who were examined by fetal echoCG at the Seoul National University Children's Hospital from January 2008 through April 2011. Results The mean gestational age at diagnosis was 26.2±5.2 weeks. The mean age of mothers at diagnosis was 31.7±3.8 years. We identified indications for fetal echoCG in 279 cases. The most common indication was abnormal cardiac findings in obstetrical screening sonography (52.0%). Among the 313 echoCG results, 127 (40.6%) were normal, 13 (4.2%) were minor abnormalities, 35 (11.2%) were simple cardiac anomalies, 50 (16.0%) were moderate cardiac anomalies, 60 (19.2%) were complex cardiac anomalies, 16 (5.1%) were arrhythmias, and 12 (3.8%) were twin-to-twin transfusion syndrome. The most common congenital heart disease was tetralogy of Fallot (23 fetuses, 15.9%). One hundred forty-eight neonates were examined by echoCG. We analyzed differences between fetal echoCG and postnatal echoCG. In 131 (88.5%) cases, there was no difference; in 15 (10.1%), there were minor differences; and in only 2 (1.4%) cases, there were major differences. Conclusion There is a recent increase in abnormal cardiac findings of obstetric ultrasonography screenings that indicate fetal echoCG. Fetal echoCG is still a good, accurate diagnostic method for congenital heart disease.

Abstract
The objective of this study was to examine the performance of early fetal echocardiography as a screening tool for major cardiac defects in a high-risk population. Fetal echocardiograms performed at 12 to 16 weeks were reviewed. Cases that did not undergo a follow-up echocardiogram at 18 to 22 weeks were excluded. Results of the early and follow-up echocardiograms were compared. Over a 4-year period, 119 early fetal echocardiograms were recorded. Of those, 81 (68%) had follow-up fetal echocardiograms. Results of the early echocardiogram were normal in 77 of 81 (95.1%) cases. Of these, the follow-up was normal in 75 of these 77 cases; in the remaining 2, the follow-up raised suspicion for a ventricular septal defect (VSD) in one and persistent left superior vena cava in the other. On the other hand, the early echocardiogram was abnormal in 4 (4.9%) cases: (1) atrioventricular canal defect, with the follow-up demonstrating a VSD; (2) hypoplastic right ventricle and transposition of the great arteries, confirmed on follow-up; (3) VSD and coarctation of the aorta, confirmed on follow-up. In the fourth case, the early echocardiogram suspected a VSD and right-left disproportion, yet the follow-up was normal. In conclusion, early fetal echocardiography appears to be a reasonable screening tool for major cardiac defects.

Abstract
OBJECTIVE To describe a novel and simple technique—simple targeted arterial rendering (STAR)—to visualize the fetal cardiac outflow tracts from dataset volumes obtained with spatiotemporal image correlation (STIC) and applying a new display technology (OmniView). METHODS We developed a technique to image the outflow tracts by drawing three dissecting lines through the four-chamber view of the heart contained in a STIC volume dataset. Each line generated the following plane: (a) Line 1: ventricular septum en face with both great vessels (pulmonary artery anterior to the aorta); (b) Line 2: pulmonary artery with continuation into the longitudinal view of the ductal arch; and (c) Line 3: long-axis view of the aorta arising from the left ventricle. The pattern formed by all three lines intersecting approximately through the crux of the heart resembles a star. The technique was then tested in 50 normal fetal hearts at 15.3–40.4 weeks' gestation. To determine whether the technique could identify planes that departed from the normal images, we tested the technique in four cases with proven congenital heart defects (ventricular septal defect (VSD), transposition of great vessels, tetralogy of Fallot and pulmonary atresia with intact ventricular septum). RESULTS The STAR technique was able to generate the intended planes in all 50 normal cases. In the abnormal cases, the STAR technique allowed identification of the VSD, demonstrated great vessel anomalies and displayed views that deviated from what was expected from the examination of normal hearts. CONCLUSIONS This novel and simple technique can be used to visualize the outflow tracts and ventricular septum en face in normal fetal hearts. Inability to obtain expected views or the appearance of abnormal views in the generated planes should raise the index of suspicion for congenital heart disease involving the great vessels and/or the ventricular septum. The STAR technique may simplify examination of the fetal heart and could reduce operator dependency.

Abstract
INTRODUCTION Congenital heart diseases are the most common prenatal and postnatal malformations. Nowadays, fetal echocardiography is a widely practiced technique; however, the impact of prenatal diagnosis on prognosis of the newborns affected by congenital heart disease remains uncertain. OBJECTIVE To assess the outcome and the changes in the spectrum of prenatally detected congenital heart disease in our tertiary care centre in 12 years of activity (1995-2006). METHODS AND RESULTS We detected 705 congenital heart diseases: 32% (223) were associated with extracardiac or chromosomal anomalies or both, and 68% (482) were isolated. Termination of pregnancy was chosen in 81% for associated anomalies and 37% for isolated anomalies (P<0.001). Of these, more than one-third occurred in hypoplasic left heart cases. The general survival rate was 72%; it was significantly lower in the group with associated heart diseases (46 vs. 80%, P<0.001). Over 12 years we noticed a reduction in the number of multimalformed fetuses and of the hypoplasic left heart cases, and a higher number of aortic arch anomalies detected. During the past 6 years of activity the survival rate obtained has significantly increased (55 to 84%, P<0.05), the termination rate has significantly decreased (35 to 14%, P<0.001) and the number of neonatal deaths has significantly decreased (39 to 10%, P<0.001). CONCLUSION The survival and the voluntary termination of fetuses with prenatally detected congenital heart diseases are strongly influenced by disease severity and by associated extracardiac or chromosomal anomalies, or both. Over 12 years, the spectrum of fetal congenital heart disease has changed and their outcome has significantly improved.

Abstract
OBJECTIVES Prenatal minimally invasive therapy represents a challenging option for reducing long-term complications of pathological fetal heart development. Here, the potential of the chick embryo as a model for ultrasound-guided intrauterine cardiac intervention is explored. METHODS Chick embryos were incubated for 18 days in fenestrated eggs and their hearts were punctured in ovo under ultrasound guidance. Indian ink and Nile blue sulfate were applied to mark the injection channel. After cardiac intervention, embryos were further incubated and subsequently sacrificed for macroscopic and histological evaluation of the heart. RESULTS Stereomicroscopic analysis revealed that the catheter had successfully penetrated the cardiac ventricular wall in 26/38 embryos. The myocardium was not severely injured. Histological evaluation showed that the myocardium had almost reoccluded after the intervention and that the injection channel was clogged with fibrin. In one case, the embryo was not sacrificed, but was removed from the egg 24 h after the intervention, with no signs of cardiac dysfunction, and was followed up for 6 months. CONCLUSIONS Intrauterine ultrasound-guided heart intervention in the human fetus can be simulated in the chick embryo. Fenestrated eggs have to be used because the egg shell and shell membrane are impermeable to ultrasound.

Abstract
BACKGROUND/PURPOSE Outcome for fetuses with prenatally detected congenital heart disease (CHD) and/or cardiac arrhythmias is important for prenatal counseling and perinatal management; however, there exists little literature regarding the outcome for CHD diagnosed in utero in Taiwan. Therefore, we attempted to investigate the outcome for fetuses with CHD and/or cardiac arrhythmias diagnosed prenatally at a tertiary care medical center in Taiwan. METHODS Between January 1995 and December 2000, 339 patients referred to the National Taiwan University Hospital for fetal echocardiography were included in this study. Medical records were reviewed retrospectively to determine the salient clinical characteristics for all fetuses. RESULTS CHD was found in 103 fetuses. Gestational age at diagnosis ranged from 17 to 40 weeks; in 37 cases (35.9%) the diagnosis was made before 24 weeks. Mean gestational age at diagnosis was 27.8 weeks. Of the 103 cases, 15 fetuses (14.6%) had major extra cardiac malformations and 15 fetuses (14.6%) had chromosomal abnormalities (five had both) and 30 pregnancies (29.1%) were terminated. Of the remaining 73 pregnancies, three (4.1%) of the fetuses died in utero and 28 (38.4%) postnatally, with 42 (57.5%) surviving. The mortality rates were both 60% in cases with extracardiac or chromosomal anomalies. Arrhythmias were identified in 25, and two pregnancies involving hydrops fetalis were terminated. Of the remaining 23 continued pregnancies, two (8.7%) with long QT syndrome expired postnatally. CONCLUSION Outcome for fetuses with prenatally detected CHD remains poor, with the prognosis negatively influenced by the presence of complex heart defects as well as extracardiac and chromosomal anomalies. However, prognosis is good for fetuses with cardiac arrhythmia, except with long QT syndrome or hydrops fetalis.

Abstract
OBJECTIVE Congenital heart diseases (CHD) are the most common congenital anomalies, and most cases occur in the low-risk population. Prenatal ultrasound screening based on visualization of the four-chamber view has had disappointing results in detecting these anomalies thus far. The aim of this study was to evaluate the diagnostic accuracy of ultrasound screening based on the combination of the four-chamber and outflow-tract views. METHODS We conducted a multicenter prospective observational study in 15 obstetric units in the Piedmont Region, Italy. All operators received specific training. Data were recorded regarding visualization of the four-chamber view and the outflow tracts at each routine scan in pregnancies without any risk factor. When an anomaly was suspected, the patient was sent to the referral center. We obtained the follow-up data of the newborns until discharge from hospital and calculated the diagnostic accuracy of the test. RESULTS 9074 ultrasound scans were performed on 7041 women and complete follow-up information was available for 6368 of them. Fifty-eight cases of CHD were observed at birth or postmortem (prevalence 9.1 per thousand); 38 of them were diagnosed in utero. The sensitivity of the test was 65.5%, the specificity 99.7%, the positive predictive value 70.4% and the negative predictive value 99.7%. The sensitivity of the four-chamber view alone was 60.3%. CONCLUSIONS The sensitivity was significantly higher than that in a similar study performed in 1997 in the same setting. This improvement can be attributed in part to extension of the examination to the outflow-tract view, but also to technological developments and better training of the operators.

Abstract
Fetal echocardiography allows for early detection of congenital heart disease, and pregnancy termination may be an option in cases of complex defects. In the current study, the most important factors contributing to the diagnosis and termination of affected pregnancies are reviewed and their combined effect on the future prevalence of liveborn congenital heart disease is evaluated. The relative reduction of the prevalence of the most severe forms of congenital heart disease is estimated as the product of the probability that (1) a fetal cardiac screening is performed (p (evaluation)), (2) an affected pregnancy is detected (P (detection)), (3) pregnancy termination is decided following antenatal diagnosis (P (decision)). In areas where termination of pregnancy is a realistic and supported option, a universal sonographic screening of all pregnancies (P (evaluation) = 1), with an average reported sensitivity of 35% and a termination rate of 43% following antenatal diagnosis, would result in a 15% overall reduction of the prevalence of the most severe forms of congenital heart disease. However, wide variability exists regarding the defect-specific estimates (2-50% prevalence relative reduction) due to considerable differences in the reported diagnostic sensitivity and termination rates associated with each heart defect. If an earlier diagnosis could be achieved, which is reported to be associated with an average 1.4-fold increased probability of termination, the overall reduction of the prevalence of congenital heart disease could approach 21%. As the skills of obstetric and pediatric cardiology sonographers improve, fetal echocardiography is expected to have a substantial impact on the future epidemiology of liveborn congenital heart disease.

Abstract
OBJECTIVE The purpose of this study was to determine whether patterns of referral for fetal echocardiography (FE) and the subsequent yield for structural congenital heart disease (CHD) have changed between 1985 and 2003. METHODS All FE performed between 1985 and 2003 at Yale-New Haven Hospital was reviewed. The primary indication for study and the presence of structural CHD were recorded, and data were analyzed for trends. Linear regression with Pearson coefficient calculation and Mantel-Haenszel chi(2) analysis were performed (P < .05 significant). RESULTS Between 1985 and 2003, 10,806 patients had FE at Yale-New Haven Hospital, and 774 cases of structural CHD were detected. The annual number of studies and rate of detected structural CHD remained constant through the study period. There was a significant increase in the proportion of studies for diabetes, maternal structural CHD, suspicious 4-chamber heart, and family history of cardiac disease. There was a significant decrease in the proportion of studies for a previous child with structural CHD, cardiac teratogen exposure, other fetal anomalies, aneuploidy, fetal arrhythmia, and nonimmune hydrops. The percentage of structural CHD detected by indication remained constant through the study period. Subgroup analysis of diabetes revealed an increase in class B diabetes, while classes C and D remained stable. CONCLUSIONS This is one of the largest series of FE and suggests that the pattern of indications has changed since 1985. Specifically, referral for diabetes (mostly class B) has increased without a change in yield of structural CHD by indication for sonography. The changing referral patterns reflect a change in obstetric demographics and has implications for obstetric care.

Abstract
OBJECTIVE To investigate whether pulsatility of ductus venosus (DV) flow velocity waveforms is of diagnostic value in predicting survival in fetuses with congenital heart disease (CHD). METHODS In a cross-sectional study, Doppler investigation of DV and umbilical artery blood flow was performed in 58 fetuses with isolated structural CHD, without other sonographically detectable structural or chromosomal abnormalities or tachyarrhythmia. The pulsatility index for veins of DV (DV-PIV) waveforms was expressed as multiples of the 95th centile (Mo95th) of the reference ranges for gestational age. The PIV was related to intrauterine and neonatal mortality within the first 6 months of life. Terminations of pregnancies and neonates with additional abnormalities detected after birth were excluded from statistical analysis. For statistical analysis, the different types of heart defects were separated into atrial and/or ventricular (AV) septal defects, right or left ventricular in- and outflow tract abnormalities and others. RESULTS After exclusion of 9 pregnancies (2 cases with failure of measurements of DV-PIV, 2 neonates with additional malformations, and 5 terminations of pregnancies), 49 cases were available for statistical analysis. The umbilical artery pulsatility index was within normal ranges in all but 1 case with AV canal and hydrops. In 7 pregnancies intrauterine fetal deaths occurred and 6 of them were hydropic. The median gestational age at birth for liveborn neonates was 39.0 weeks (range 27.8-41). There were 6 postnatal deaths, all but 1 within 28 days of delivery. The remaining fetuses survived for at least 6 months. The overall mortality rate was 27% (13/49). The DV-PIV was significantly higher in non-survivors than in survivors (median of Mo95th and interquartile ranges 1.48 (1.04-1.95) vs. 0.81 (0.70-1.15); p = 0.01). Analysis of subgroups showed significant differences for AV septal defects and abnormalities affecting predominantly the right ventricle (p = 0.046 and 0.043, respectively). Ten out of 13 non-survivors showed an abnormal DV-PIV (sensitivity 77%) as compared to 12 out of 36 survivors (specificity 67%). All hydropic fetuses (n = 6) showed an abnormal DV-PIV and ended in intrauterine deaths. CONCLUSIONS Evaluation of the DV pulsatility is a useful additional variable for predicting the risk for mortality in fetuses with isolated structural CHD, in particular in fetuses with defects of the AV septum and with defects affecting predominantly right ventricular function. As there is no fetal hydrops without abnormal DV, this is another sign for the association of DV and cardiac failure.

Abstract
OBJECTIVE To determine if a policy of universal fetal echocardiography for all pregnant diabetic women is cost-effective as a screening tool for congenital heart defects. STUDY DESIGN Using a decision-analysis model, we compared the cost-effectiveness of four screening strategies: (1) none--no ultrasound is performed; (2) selective fetal echocardiography after abnormal detailed anatomic survey; (3) fetal echocardiography for only high hemoglobin A1C, and (4) universal fetal echocardiography for all diabetics. The sensitivity and specificity for each strategy were derived by literature search. The analysis was from a societal perspective using a willingness-to-pay threshold (50,000 dollars) and a theoretic cohort of 40,000 pregnant diabetics. Costs included costs of tests and the costs of complications and of raising a child with a cardiac defect. Outcomes were reported as cost per quality-adjusted life years (QALY) gained for each congenital heart defect prevented by each strategy and the number of congenital heart defects detected. One-way, multiway and probabilistic sensitivity analyses were performed. RESULTS Compared with the other strategies, selective fetal echocardiography after abnormal detailed anatomic survey costs less per QALY gained for cardiac defect screening. Although universal fetal echocardiography was associated with a higher detection rate for cardiac defects, it was more costly. The sensitivity analyses revealed a robust model over a wide range of values. CONCLUSION Under the baseline assumptions, selective fetal echocardiography after an abnormal detailed anatomic survey is more cost-effective compared with universal fetal echocardiography as a screening strategy for cardiac defects in pregnant diabetics.

Abstract
PURPOSE The present study was conducted to evaluate the indications for fetal echocardiography in a tertiary-care obstetric sonography practice and to determine the incidences of confirmed congenital heart disease for each primary indication. METHODS A retrospective analysis of all pregnant women referred to a pediatric cardiology unit for fetal echocardiography by the tertiary-care sonography unit over a 2-year period was performed. The primary indications for referral for fetal echocardiography were obtained from the sonographers' reports. Outcome data were extracted from the fetal echocardiograms, postnatal echocardiograms or pathology and autopsy reports, and patient medical records. RESULTS Of 6,002 pregnant women who had undergone prenatal sonographic examination during the study period, 275 (4.6%) had been subsequently referred for fetal echocardiography. The most common primary indication for referral had been abnormal cardiac findings on the prenatal sonographic examination, which had been present in 64 (23.3%) of the 275 cases. In 44 (69%) of those 64 cases, congenital heart disease had been confirmed. Among the 211 patients who had had normal cardiac findings on prenatal sonography but had been referred for fetal echocardiography owing to other primary indications, congenital heart disease had been confirmed in only 7 cases (3.3%). CONCLUSIONS An abnormal cardiac finding during prenatal sonographic examination is a common primary indication for fetal echocardiography and is more useful for identifying congenital heart disease than are other risk factors. Careful routine cardiac screening during routine prenatal sonographic examination may facilitate further investigation and treatment.

Abstract
Congenital heart disease has the characteristics of a disease that is suited to screening, and the four-chamber view is an effective screening tool with a sensitivity of 40% to 50%. The use of multiple cardiac views can increase the pre-natal detection to 60% to 80%. Given that most infants with congenital heart disease are born to low-risk women, routine screening is warranted. Early pre-natal diagnosis provides an opportunity to exclude associated extracardiac and chromosomal abnormalities, discuss pregnancy options, adjust obstetric management, prepare parents for delivery of an affected baby, and plan delivery in a tertiary care center. Despite the widespread use of ultrasonography, only 15% to 30% of infants with congenital heart disease are identified prenatally. There is a need to do better.

Abstract
OBJECTIVES We hypothesized that increased facility with fetal echocardiographic diagnosis by obstetricians is associated with changes in its indications and yields. METHODS We reviewed 300 fetal echocardiograms (December 2002-August 2003) and compared our findings with previous studies. RESULTS Mean maternal age was 31 +/- 6 (range 16-44) years. Gestational age was 24 +/- 5 weeks (mean +/- SD; median 22, range 15-38). Indications for fetal echocardiography included family history of congenital heart disease (CHD) (23%), maternal diabetes (18%), obstetrical scan suspicious for CHD (13%), arrhythmia (12%) maternal rheumatologic disease (7%), extracardiac congenital anomalies (6%), chromosomal anomaly (6%) and exposure to a potential fetal teratogen (5%). High yield indications included chromosomal anomaly (47%) and a suspicious obstetrical scan (42%). Low yield indications included family history of CHD (4%) and teratogen exposure (0%). 1/7 of the patients with increased nuchal translucency had pulmonary atresia/intact ventricular septum. No anomalies were associated with the single umbilical artery. CONCLUSION Indications and yields of fetal echocardiography have changed over the last decade. The frequency of an obstetrical scan suspicious for CHD has increased 2.5 to 3 times over a decade and continues to have high yield. Thus, increasing prenatal detection of CHD depends, to a large extent, on increasing the skills of obstetricians.

Abstract
OBJECTIVE To investigate the outcome of fetuses affected by congenital heart defects (CHD), either detected or undetected at ultrasound screening, according to their complexity and severity. DESIGN The study group comprised 3633 malformed fetuses entered into the Eurofetus database of which 798 had CHD. We compared the short-term outcome in cases where a CHD was detected by ultrasound screening with that in cases where a CHD was not detected. Isolated and associated CHD (ICHD and ACHD) and the degree of severity of defects were considered separately. Outcome data included termination of pregnancy (TOP), intrauterine fetal death, neonatal death (< 6 days after birth), gestational age at diagnosis and at delivery, mode of delivery and birth weight. RESULTS Of the 798 fetuses with CHD, 595 had ICHD and 203 had ACHD. The diagnosis of an anomaly was made significantly earlier in ACHD cases. TOP was chosen in 28% of cases with a prenatal diagnosis of CHD, 20% for ICHD and 37% for ACHD (P < 0.001). The survival rate of antenatally diagnosed fetuses was lower in those with ACHD than in those with ICHD (P < 0.001) and lower for fetuses with antenatal diagnosis than with postnatal diagnosis (P < 0.001); this was due to significant differences in the complexity and severity of the defect. Premature delivery (< 32 weeks) was more frequent in fetuses in which an antenatal diagnosis of CHD had been made. Severe CHD were diagnosed earlier and were associated with a higher rate of TOP and spontaneous loss. CONCLUSIONS The severity of CHD has a positive influence on the sensitivity of screening but a negative influence on the outcome. CHD that are not diagnosed antenatally include a high proportion of benign malformations. This explains the apparent paradox of a poorer outcome in fetuses in which a CHD was detected prenatally compared to those fetuses in which the defect was undetected prenatally. However, prenatal diagnosis provides parents with the option of TOP or of preventive care in specialized centers.

Abstract
OBJECTIVES To analyse the spectrum and frequencies of observed malformations; to evaluate associated extracardiac and chromosomal anomalies and outcomes in each diagnostic category; to demonstrate the need for a multidisciplinary approach to the diagnosis of CHD in the fetus. METHODS From January 1994 to December 1999, 450 cases of CHD were detected among 4052 pregnancies at risk of fetal CHD seen at our combined unit. Confirmation of the diagnosis was not available in 50 cases, leaving 400 cases for analysis. From our computerized database, the following variables were retrieved and analysed: indication, gestational age at diagnosis, associated extracardiac anomalies, karyotype, natural history, pregnancy and feto-neonatal outcome. RESULTS CHDs most commonly detected were VSD (75 cases), AVSD (40 cases) and HLH (37 cases). The aneuploidy rate was 29.3% in the 355 cases submitted for karyotyping (25.9% in the whole series), with a prevalence of trisomy 21 and 18 (48 and 30 cases, respectively). The aneuploidy rate was highest for AVSD (80%), coarctation (49%), tetralogy of Fallot and VSD (45%). Associated extracardiac anomalies were present in 29.5% of the cases (118/400). As for pregnancy outcome, there were 150 (37.5%) terminations of pregnancy, 16 (4%) intrauterine fetal deaths and 85 (21.3%) neonatal deaths. The remaining 149 neonates are alive (37.3% survival rate). The termination rate for pregnancies in which CHD was detected at a gestational age <25 weeks was 65.2%. Evolutive changes determined progressive prognostic deterioration in 21 cases (5%), consisting of semilunar valve obstructions and development of ventricular hypoplasia. CONCLUSIONS The high association rate with extracardiac and chromosomal anomalies (29.3% and 25.9%) and the possible progressive prognostic deterioration require a multidisciplinary team for correct management and follow-up. Survival of fetuses with certain CHD is severely reduced, in comparison with postnatal figures, for the common association with aneuploidies.

Abstract
OBJECTIVES Most pregnant women in New South Wales undergo obstetric ultrasound examination, including some assessment of fetal cardiac anatomy. We aimed to review the spectrum of cardiac defects, management and outcome data of all fetuses with diagnosis of major congenital heart disease between 1994 and 1996 and compare them to major congenital heart disease in infants born during the same 3-year study period. METHODS Descriptive comprehensive study of the New South Wales population. Study centers included the single fetal echocardiographic referral service and the two pediatric cardiac centers of New South Wales. RESULTS Ninety-seven fetuses and 562 infants with major congenital heart disease were identified (240,000 livebirths), resulting in a prenatal detection rate of 15%. Anomalies detectable by cardiac four-chamber views were diagnosed at an average rate of 30% (68/229) in utero. By contrast, lesions associated with abnormal ventricular outflow and great artery views were detected in only 6.7% (29/430; P < 0.0001) of cases prior to birth. Of the 97 fetuses, 29 were aborted, 16 died in utero, and 9 died early postnatally without treatment. Within 2 weeks of age, 23% with fetal and 40% (P < 0.05) with infant major congenital heart disease diagnosis required an intervention, mainly for patent ductus arteriosus dependent lesions. Postnatal survival was similar for the fetal and infant series up to 2 years of age: 77% (95% confidence interval 64-90%) vs. 85% (95% confidence interval 82-88%). CONCLUSIONS Prenatal diagnosis has important implications for pregnancy outcome, in particular for univentricular lesions. However, the present mode of obstetric routine ultrasound scanning fails to identify most ductus arteriosus dependent cardiac lesions with a predictable need for early postnatal intervention.

Abstract
OBJECTIVE To assess the level of agreement between obstetric and pediatric cardiologist sonographers' diagnosis of fetuses with suspected congenital heart disease and to compare this with the final postnatal diagnosis. DESIGN We retrospectively reviewed the notes of 1037 patients undergoing fetal echocardiography over a 5-year period (1995-99) at the principal tertiary referral center for fetal cardiology in New South Wales, Australia. The median gestational age at presentation was 21 weeks (range 17-38) with 49% of the scans performed at < 21 weeks and a further 17% performed at 21-24 weeks. The accuracy of the fetal cardiac diagnosis was validated by neonatal cardiac investigation or autopsy. RESULTS A total of 249 cases of congenital heart disease were identified antenatally during this 5-year period with the majority (84%) referred because of suspicion of a cardiac malformation during an obstetric scan. Of the 268 fetuses with congenital heart disease suspected by obstetric sonographers, 209 had confirmed cardiac defects. Complete correlation between obstetric sonographers' and pediatric cardiologists' prenatal cardiac findings was achieved in 62% of cases. There were major differences involving the atrioventricular morphology in 18% of cases and the outflow tract anatomy in 20%. Complete agreement between prenatal and postnatal diagnosis in fetuses with complex congenital heart disease was achieved in 59% of cases for obstetric sonography (17% false positive; 41% false negative) and 95% for fetal echocardiography by pediatric cardiologists (2% false positive; 5% false negative). CONCLUSIONS Improved accuracy in diagnosis can be achieved through a pediatric cardiologist with special skills in fetal echocardiography working collaboratively with obstetric sonographers to optimize the details of diagnosis. This may influence management and counseling.

Abstract
A systematic approach to examination of the fetal heart will enhance the detection of structural cardiac abnormalities and will enable an accurate diagnosis of congenital heart disease to be made. Once an abnormality has been detected appropriate counselling must be provided and adequate support given to the parents. Associated extracardiac abnormalities should be sought for, and plans for the remainder of pregnancy, delivery and postnatal management should be made using a team approach. In cases resulting in termination of pregnancy, permission for autopsy should be sought to confirm the ultrasound diagnosis. Although in-utero therapy is available for some forms of fetal arrhythmia and a few limited cases of structural heart disease, this should be conducted in tertiary centres.

Abstract
Series reporting congenital heart disease detected in utero all indicate a different spectrum and severity of disease than is seen in postnatal series, with a tendency toward more severe disease with a poorer outcome. This is largely because of the manner in which cases are selected for fetal echocardiography. As most forms of heart disease occur in otherwise normal pregnancies with no high risk features, detection of these cases is dependent on the skill of the ultrasonographer performing general obstetric scanning. Although detection of even major malformations seen in the four chamber view, is still less than perfect, it is improving. In the future, it is expected that malformations will be detected in earlier pregnancy and examination will include evaluation of great artery structure. This will give more parents the option of termination of pregnancy in complex disease. Alternatively, in continuing pregnancies, the outcome for the affected neonate will be improved by ideal perinatal care.

Abstract
BACKGROUND As prenatal diagnosis of congenital heart disease has gained in popularity, the questions of whether prenatal diagnosis of congenital heart disease is beneficial for the patient and whether fetal echocardiography has improved the prognosis of congenital heart disease are arising. METHODS We compared four patients with prenatally diagnosed hypoplastic left heart syndrome (HLHS) with 10 patients of non-prenatally diagnosed HLHS from the view points of (i) age at transfer to our Children's Hospital; (ii) whether the oxygen was inhaled during perinatal period; (iii) whether prostaglandin E1 was administered in the period of waiting before operation; (iv) whether the patient had ductal shock; (v) timing of operation; and (vi) surgical outcome. RESULTS The timing of the transfer to our Children's Hospital was earlier in prenatally diagnosed group than in non-diagnosed group. Oxygen was not given to any of the patients in prenatally diagnosed group. In contrast, oxygen inhalation was given in two of 10 patients in the non-prenatally diagnosed group. Prostaglandin E1 was administrated in three of four patients in the prenatally diagnosed group and seven of 10 patients in the non-prenatally diagnosed group. In terms of ductal shock, none of the patients in prenatally diagnosed group had ductal shock. However, four of 10 patients had ductal shock in the non-prenatally diagnosed group. The median age at Norwood operation was 7 days in the prenatally diagnosed group; however, it was 19 days in non-prenatally diagnosed group. Surgical outcomes showed no significant changes between the two groups. CONCLUSIONS Prenatal diagnosis of HLHS was surely beneficial for preventing ductal shock and for keeping the patients' preoperative condition good.

Abstract
OBJECTIVES To analyse the evolution and outcome in utero and after birth of infants with a fetal diagnosis of congenital heart disease. DESIGN Inclusion criteria were the fetal diagnosis of congenital heart disease, confirmed postnatally or postmortem, and a complete follow up in utero and after birth. SETTING 20 centres operating prenatal echocardiographic screening. PATIENTS 847 cases were included in the study. Gestational age at diagnosis ranged from 15-39 weeks; in 370 cases (43.7%) the diagnosis was made before 24 weeks' gestation. RESULTS 245/847 cases (28.9%) were terminated during pregnancy, 227 following early diagnosis; 128/245 cases (52. 2%) had associated anomalies and 117/245 (47.8%) had serious congenital heart disease. Of the remaining 602 cases that continued the pregnancy, 72 (11.9%) died in utero, 259 (43%) died postnatally (83 after surgery or invasive procedures), and 271 infants (45%) survived and presently range in age from 18 months to 13 years old. The mortality rate was higher in cases with associated extracardiac or chromosomal anomalies (68% and 74% of cases continuing pregnancy, respectively), and in cases with heart failure and complex cardiac defects. CONCLUSIONS The data confirm a relevant fetal and postnatal loss in cases with complex congenital heart disease, and major clinical use of prenatal diagnosis in the management of ductus dependent anomalies. Negative prognostic factors for the outcome were associated anomalies and heart failure.

Abstract
Echocardiography is an extraordinarily useful imaging technique in fetuses, infants, children, and adolescents. Recent technologic innovations have expanded its versatility in the pediatric population. However, limited societal resources, limitations inherent to ultrasound imaging, and numerous imaging options even within the field of pediatric echocardiography necessitate the discriminate and thoughtful use of echocardiography in children. The clinical assessment remains a critical prelude to echocardiographic examination of the pediatric cardiovascular system.

Abstract
Cardiac malformations are the most frequent and serious fetal malformations. However their prenatal diagnosis is the less easy. Fetal echocardiography is the main diagnostic tool; in addition it is helpful for the therapeutic orientation. Only 30% of fetal heart diseases are detected on account of maternal or fetal indications, most of them being discovered without any known risk factor. In order to improve its diagnostic sensitivity, fetal echocardiography must include a four chambers view and a study of ventricular and arterial connection. Nevertheless, many heart diseases remain undetected, most of them being minor with favorable prognosis. Search of an extracardiac abnormality and karyotype analysis must be performed in order to explicit the prognosis. Fetal arrhythmias can be analyzed by study of the atrial and ventricular contraction using M-mode echocardiogram or Doppler mode; most of them are supraventricular and accessible to maternal therapy. The sustained fetal bradycardia is frequently a complete heart block whose prognosis depends upon its association with a heart defect and/or a ventricular escape. Antibodies SS-A and SS-B are frequently associated with complete heart block without structural heart defects. Hypertrophic cardiomyopathy may be observed in fetus of diabetic mothers needing an accurate evaluation of the thickness of the interventricular septum. Echocardiography is a part of fetal medicine, which includes the different specialties devoted to the fetus.

Abstract
Our objective was to document the prognosis of cases with fetal heart malformations (FHM). Forty-two fetuses assessed both in a regional fetal medicine and paediatric cardiology unit were classified prenatally into isolated FHM or those associated with extra-cardiac structural or karyotypic anomalies (ECA) and this classification was not changed subsequently (analogous to an intention to treat analysis). The end points studied included chromosomal abnormality, pregnancy outcome and follow-up at one year of age. FHM were isolated in 16 (38%) and associated with ECA in 26 (62%) of cases. The karyotypic abnormality rate was 8/42 (19%) overall and 8/26 (31%) in ECA cases. The pregnancy outcome included termination of pregnancy in 19 (45%), intrauterine death of two (5%) and live birth in 21 (50%). 12/16 (75%) of isolated FHM cases were live born compared with 9/26 (35%) of ECA cases (P < 0.03). Of the isolated FHM live born babies, 8/12 (67%) were alive at the end of the first year and seven of these were growing normally and did not require cardiac medication. However, a considerable proportion of their first year was spent in hospital (median 8%, interquartile range 5-10). Only one of nine ECA live born cases was alive but with poor growth and dependence on cardiac drugs at one year. These data confirm previous findings in prenatal diagnosis series that the prognosis for FHM is worse than that reported in studies of congenital heart disease at birth and is strongly dependent upon the presence of ECA. In their absence, outcome is better than previously published. Counselling must take place only after full fetal medicine assessment and should be based upon prenatal data.

Abstract
Owing to the widely different levels of experience of examiners, there is a large discrepancy in study results of second trimester ultrasound screening for fetal malformations, which is a result of varying levels of obstetric scanning expertise prevalent at the reporting centre. This holds particularly true for the prenatal diagnosis of congenital heart disease where detection rates ranging from 0 per cent to 60 per cent are being reported. On the other hand, congenital heart disease affects about 4-8 per 1000 live births and is a leading cause of infant mortality, whereas prenatal diagnosis could possibly prevent death and long-term morbidity in some of these neonates. Various screening concepts for more effective detection of congenital heart diseases are analysed in this article, including the more recent technique of early echocardiography between 13 and 15 weeks of gestation. High-risk groups are defined and the group of fetuses with increased thickness of nuchal translucency seems to be of particular interest.

Abstract
OBJECTIVE To review the outcomes of 193 fetuses with cardiac abnormalities detected by echocardiography. METHODS A total of 422 fetuses between 16 and 41 gestational weeks, referred to paediatric cardiologists for detailed echocardiography, were included in this study. RESULTS Structural heart defects were found in 55 (28%), isolated arrhythmia in 105 (54%), and other non-structural abnormalities (dilated cardiomyopathy, hypertrophic cardiomyopathy, aneurysm of the foramen ovale, isolated pericardial effusion or echogenic foci) in 33 (17%) of 193 fetuses. Total mortality was 26%. The prognosis was poor in fetuses with structural heart defects; 37 of 55 cases (67%) died in utero or postnatally. Chromosomal abnormality was associated with structural heart defect in 38% of fetuses, of whom 38% died. Among fetuses with isolated arrhythmia survival was 95%. Poor outcome was associated with complete heart block (n = 14) in 2 (14%) fetuses with hydrops and heart rate of less than 55 per minute, and with supraventricular tachycardia (n = 21) in three (14%) neonates delivered prematurely at a mean gestational age of 33 weeks. Furthermore, nine of 12 fetuses (75%) with structural heart defects and arrhythmia died. Among fetuses with non-structural cardiac abnormalities, survival was 73%. Poor outcome was evident in fetuses with dilated cardiomyopathy in eight of 13 (62%) and with hypertrophic cardiomyopathy in one of eight (13%) of cases. CONCLUSIONS Factors associated with a poor prognosis were: structural heart defect associated with chromosomal abnormality or arrhythmia, congestive heart failure associated with supraventricular tachycardia or complete heart block, especially if delivery occurs preterm; and fetal hydrops with congestive heart failure and atrioventricular valve regurgitation.

Abstract
OBJECTIVES In this study we used a population-based approach to assess the impact of fetal echocardiography on a well defined birth population with nearly complete ascertainment of cardiac defects. BACKGROUND Although fetal echocardiography is being used more frequently in the prenatal diagnosis of congenital cardiac malformations, its impact on the diagnosis and surveillance of cardiac defects has not been described in defined populations. METHODS All stillborn and live-born infants with diagnosed cardiac defects and whose mothers resided in the metropolitan Atlanta area from January 1990 through December 1994 were ascertained through an established birth defects surveillance system. All fetuses with cardiac defects diagnosed prenatally by a pediatric of cardiac defects, diagnostic trends and adverse fetal outcomes were described. RESULTS We identified 1,589 infants with congenital cardiac malformations, for a live-birth prevalence rate of 8.1/1,000 (95% confidence interval [CI] 7.8 to 8.6). Overall, 97 (6.1%) of these cases of cardiac malformations were diagnosed prenatally. The proportion of cardiac defects diagnosed prenatally rose from 2.6% in 1990 to 12.7% in 1994, a nearly fivefold increase. The proportion of cardiac defects diagnosed prenatally during the study varied by the type of defect, from a low of 4.7% for atrial septal defects to a high of 28% for hypoplastic left heart syndrome. Prenatally diagnosed cardiac malformations were associated with a high incidence of infant mortality (30.9%, 95% CI 2.4 to 5.4) and fetal wastage (17.5%, 95% CI 6.2 to 11.3). CONCLUSIONS These data show that fetal echocardiography is being used increasingly in the prenatal diagnosis of congenital cardiac malformations in metropolitan Atlanta. Few pregnancy terminations were reported as a result of such diagnoses. However, the study had limited power (10%) to detect a meaningful decrease in birth prevalence rates for congenital heart disease. In addition, survival of infants was not improved after prenatal diagnosis with fetal echocardiography.

Abstract
Left and right atrial isomerism, comprising congenital heart defects with disturbances in normal left-right asymmetry, are phenotypically distinct after birth, although animal models suggest a common embryologic origin. We postulated that the prenatal phenotype may indeed be similar in both syndromes but that differential fetal loss is responsible for the distinct postnatal phenotypes. Distinctive fetal echocardiographic features of these syndromes have not been described in detail. We therefore sought markers of left atrial isomerism that could be recognized prenatally by echocardiography and compared our results with postnatal data to identify unique intrauterine features. We reviewed 10 cases at our center and 28 published cases of cardiac malformations with atrial isomerism detected by fetal echocardiography. Postnatal imaging and autopsies provided definitive diagnoses. Ninety-five percent of cases exhibited left atrial isomerism and formed the primary study population. Echocardiographic markers included a large azygos continuation of an interrupted inferior vena cava, atrioventricular block with structural heart disease, and viscerocardiac heterotaxy. At least 1 of these markers was seen in all of our center's cases. The incidences of most cardiac lesions detected prenatally were similar to those detected postnatally. However, although the incidences of atrioventricular septal defect and pulmonary outflow obstruction in live births were 50% and 45%, respectively, they were found much more frequently among stillbirths (80% each). In summary, we identified key fetal echocardiographic features highly sensitive for left atrial isomerism. Fetal loss selects against certain lesions such as atrioventricular septal defect. The spectrum of cardiac disease suggests a greater primitivity of the fetal heart than previously shown; the typical cardiac phenotypes are closer to right atrial isomerism than are their extrauterine presentations.
