“…When we compare diagnosis of the patients with CHD with postnatal echocardiography and autopsy data, specificity of FE in diagnosis of CHDs was 100% and sensitivity-97%. These values are better than in our first study and similar to results reported in literature (26)(27)(28). When prenatal diagnoses were compared with autopsy and postnatal echocardiography results, specificity rates varied between 70-98% (26-29).…”

Objective: Fetal echocardiography (FE) is considered for fetal, maternal or hereditary reasons in pregnants with suspect of intrauterine heart disease (IUHD). However, in few studies it was reported that most of the fetuses with IUHD are in the low-risk group (suspicion of IUHD during 2 nd trimester ultrasound, lack of good vision of the heart, self-referral). Our aim is to examine retrospectively the reasons for referral of pregnants, the results of FE, distribution of pregnants having fetuses with IUHD according to low-and high-risk factors and to evaluate reliability of FE. Methods: Our study group consisted of 1395 fetuses and 1370 pregnants underwent FE between 1999 and 2006. These cases included selfreferred women and the pregnants having previous child or family history of cardiac anomaly or referred by obstetricians. The prevalence of IUHDs in low-and high-risk pregnancies was compared by Chi-Square test. Results: The low risk group included 453 patients and the remaining 917 women were in the high-risk group. Intrauterine heart diseases were detected in 152 (10.9%) of 1395 fetuses. The prevalence of IUHDs was 19% in the low-risk group and 7% in the high-risk group. Of the152 fetuses 56.6% were in the low-risk group and 43.4% were in the high-risk group. The sensitivity of FE for diagnose of IUHDs was 97%, the specificity was 100%. Conclusion: Fetal echocardiography is highly reliable method for diagnosing of IUHDs. The most IUHDs occur in the low-risk group.

Ancak yapılan çok az sayıdaki çalışmada KKH'lı fetusların çoğunun düşük riskli (ikinci trimester ultrasonunda KKH şüphesi, kalbin iyi görüntülene-memesi, gebelerin kendi istediğiyle başvurması) gebelik grubuna dahil olduğu bildirilmiştir. Bu çalışmada bölümümüzde son yıllarda FE'si yapılan gebelerin başvuru nedenlerini, ekokardiyografi sonuçlarını ve fetuslarında KKH'ı olan gebelerin düşük ve yüksek risk faktörlerine göre dağılımlarını ve FE sonuçlarımızın güvenilirliğini retrospektif olarak değerlendirdik. Yöntemler: Çalışmamızda Ekim 1999-Haziran 2006 tarihleri arasında Ünitemizde 1536 gebeye FE yapıldı. Postnatal ekokardiyografi sonucu bilinen 1243 normal kalp bulguları olan fetus ile postnatal ekokardiyografisi ve/veya otopsisi bilinen 152 intrauterin kalp hastalıklı (IUKH) fetus olmak üzere toplam 1395 fetus ve 1370 gebe çalışma grubumuzu oluşturdu. Bu olgular, kadın hastalıkları ve doğum uzmanları tarafından yönlendirilen, kendi isteğiyle başvuran ve ailesinde veya daha önceki gebeliklerinde KKH'ğı olan gebelerden oluşmaktadır. Düşük ve yüksek riskli gebelerdeki IUKH'ğı prevalansı Ki-Kare testiyle karşılaştırılmıştır. Bulgular: Düşük risk grubunda 453 (%33.1), yüksek risk grubunda 917 (%66.9) gebe yer almaktaydı. 1395 fetusun 152'sinde (%10.9) IUKH ...

“…Unfortunately, most population studies regarding the use of ultrasonography to detect congenital heart disease have reported low sensitivities for abnormalities of the great arteries [10,12,13,28,41,42,63,64]. Studies documenting higher detection rates emphasized routine visualization of the outflow tracts in addition to the usual four-chamber view [8,22,24,25,27,32,36,37,[65][66][67].…”

Methods.A technique was developed to obtain dynamic multiplanar images of the left ventricular outflow tract (LVOT) and right ventricular outflow tract (RVOT) from volume datasets acquired with STIC. Volume datasets were acquired from fetuses with normal cardiac anatomy. Twenty volume datasets of satisfactory quality were pre-selected by one investigator. The data was randomly assigned for a blinded review by two independent observers with previous experience in fetal echocardiography. Only one volume dataset was used for each fetus. After a training session, the observers obtained standardized cardiac views of the LVOT and RVOT, which were scored on a scale of 1 to 5, based on diagnostic value and image quality (1 = unacceptable, 2 = marginal, 3 = acceptable, 4 = good, and 5 = excellent). Median scores and interquartile range, as well as inter-and intraobserver agreement were calculated for each view. Results. The mean menstrual age at the time of volume acquisition was 25.5 + 4.5 weeks. Median scores (interquartile range) for LVOT images, obtained by the first and second observers, were 3.5 (2.25-5.00) and 4 (3.00-5.00), respectively. The median scores (interquartile range) for RVOT images obtained by the first and second observers were 3 (3.00-5.00) and 3 (2.00-4.00), respectively. The interobserver intraclass correlation coefficient for the LVOT was 0.693 (95% CI 0.380-0.822), and 0.696 (95% CI 0.382-0.866) for the RVOT. For the intraobserver agreement analysis, observer 1 gave higher scores to the LVOT the second time the volumes were analyzed [LVOT: 3.50 (2.25-5.00) vs. 5.00 (4.00-5.00, p = 0.008)]. Conclusion. STIC can be reproducibly used to evaluate fetal cardiac outflow tracts by independent examiners. Slightly better image quality rating scores during the intraobserver variability trial suggests the presence of a learning curve for the manipulation and analysis of volume data obtained by STIC.

Background-Although prenatal diagnosis of transposition of the great arteries (TGA) reduces neonatal mortality, the preoperative course can be complicated in infants with a restrictive foramen ovale (FO) or a ductus arteriosus (DA) constriction. We sought to determine the specificity and sensitivity of prenatal features of physiological shunts in predicting postnatal clinical status in prenatally diagnosed TGA in babies delivered in a tertiary care center providing all facilities for neonatal urgent care. Methods and Results-The outcomes of 130 fetuses with TGA were reviewed over a period of 5.5 years. Restriction of the FO and/or constriction of the DA could be analyzed in 119/130 fetuses at 36Ϯ2.7 weeks of gestation. Twenty-four out of 119 had at least 1 abnormal shunt (23 FO, 5 DA, and 4 both). Thirteen of 130 neonates had profound hypoxemia (PaO 2 Ͻ25 mm Hg) and metabolic acidosis (pH Ͻ7.15) in the first 30 minutes and required immediate balloon atrioseptostomy. Two who had abnormal FO and DA died despite aggressive resuscitation. The specificity and sensitivity of the fetal echo in predicting neonatal emergency were 84% and 54%, respectively. The specificity and sensitivity of a combination of restrictive FO and DA constriction were 100% and 31%, respectively. Conclusions-Restriction of the FO and/or of the DA has a high specificity to predict the need for emergency neonatal care in fetuses with TGA, but the sensitivity is too low to detect all high-risk fetuses. Exceptional procedures should be considered for fetuses that have a combination of restrictive FO and DA constriction. Key Words: heart defects, congenital Ⅲ transposition of great vessels Ⅲ echocardiography P renatal detection of transposition of the great arteries (TGA) has been well established. [1][2][3][4] Of those neonates admitted with TGA, mortality is estimated around 4% and is mostly due to inadequate interatrial mixing despite prostaglandin E1 infusion. 5 We have previously reported that prenatal diagnosis of TGA reduced neonatal mortality and morbidity. 3 However, early demise of neonates with TGA has been reported even after a prenatal diagnosis, suggesting that there was no site available for mixing immediately after birth. 3,[5][6][7][8] Indeed, antenatal restriction of the foramen ovale and/or the ductus arteriosus were found predictive of significant neonatal morbidity and mortality. 9 Because the surgical mortality for the arterial switch operation is as low as 2% in many institutions, 10 -13 the preoperative mortality is a major issue in the management and outcome of infants with TGA. Here, we reviewed the prenatal features of the foramen ovale and of the ductus arteriosus in all our cases of prenatally diagnosed TGA to address the relation between prenatal echo features and need for urgent intervention. Methods PopulationOne hundred thirty consecutive patients with a prenatal diagnosis of TGA were identified over a period of 5.5 years (November 1, 1997 to February 28, 2003. TGA was suspected during routine prenatal ultrasonogra...
