J Am Heart Assoc 2023; 12:e030083. [PMID: 37929767 PMCID: PMC10727408 DOI: 10.1161/jaha.123.030083] [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: 03/07/2023] [Accepted: 10/09/2023] [Indexed: 11/07/2023]
Abstract
Background Although aortic dilation is common in tetralogy of Fallot (TOF), its progression and risk of dissection are not well understood. The mechanism of dilation is primarily attributed to increased flow in utero; an alternative is unequal septation of the truncus arteriosus resulting in a larger aorta and inherently hypoplastic pulmonary artery (PA). If the latter is true, we hypothesize the aorta to PA ratio in TOF is stable throughout gestation, and sums of great artery dimensions are similar to controls. Methods and Results We performed a single-center retrospective study of fetuses with TOF (2014-2020) and matched controls. We compared sums of diameters, circumferences, and cross-sectional areas of the aorta and PA and evaluated the aorta to PA ratio across gestation in 2 TOF subtypes: pulmonary stenosis and atresia (TOF-PA). There were 100 echocardiograms with TOF (36% TOF-PA) with median gestational age of 31 weeks (interquartile range 26.5-34.4) and median maternal age of 34 years (interquartile range 30-37). There were no differences in sums of great artery dimensions between TOF-pulmonary stenosis and controls. In TOF-PA, sums were significantly lower than controls (P values <0.01). The aorta to PA ratio was stable throughout gestation (Pearson's r=0.08 [95% CI, -0.12 to 0.27], -0.06 [95% CI, -0.25 to 0.14]). Conclusions The aorta in fetal TOF is large but grows proportionally throughout gestation, with sums of great artery dimensions similar to controls. TOF-PA appears distinct from TOF-pulmonary stenosis (with smaller sums), warranting further investigation. In conclusion, our findings suggest an intrinsic developmental mechanism contributes to aortic dilation in TOF.

"Y Sign" at the Level of the 3-Vessel and Trachea View: An Effective Fetal Marker of Aortic Dextroposition Anomalies in the First Trimester. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2018; 37:1869-1880. [PMID: 29280176 DOI: 10.1002/jum.14533] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/28/2017] [Revised: 09/22/2017] [Accepted: 10/09/2017] [Indexed: 06/07/2023]
Abstract
OBJECTIVES The "Y sign" at the level of the 3-vessel and trachea view corresponds to thinning of main pulmonary artery and arterial duct and a dilated transverse aortic arch. The purpose of this study was to evaluate the Y sign for the diagnosis of aortic dextroposition anomalies at the time of the first-trimester scan and to assess the screening performance of only the Y sign, only abnormal left axis deviation (axis sign), and their combination for the diagnosis of aortic dextroposition anomalies. METHODS A prospective evaluation of 6025 pregnant women undergoing first-trimester ultrasonography was conducted. The cardiac axis was measured in all examined patients and considered abnormal (positive axis sign) at greater than 57 °. The frequency of the Y sign and the axis sign was assessed for this population, and their screening performance for the diagnosis of aortic dextroposition anomalies was calculated. RESULTS A total of 5775 patients fulfilled the inclusion criteria. Aortic dextroposition anomalies were diagnosed in 17 cases (tetralogy of Fallot in 8 and Fallot-like double-outlet right ventricle in 9). The Y sign was found in 18 of 5775 (0.3%) fetuses examined, of which 7 of 18 were confirmed with tetralogy of Fallot, 9 of 18 with a Fallot-like double-outlet right ventricle, and 2 of 18 with pulmonary stenosis. A positive axis sign of greater than 57 ° was found in 20 fetuses, including 4 with normal heart anatomy. The sensitivity values of the Y sign, the axis sign, and their combination were 94%, 76%, and 94%, respectively. CONCLUSIONS Visualization of the Y sign should increase the suspicion of aortic dextroposition anomalies in the late first trimester. The screening performance of the Y sign alone and in combination with an abnormal cardiac axis was high and may aid in the early diagnosis of aortic dextroposition anomalies in the fetus.

Abstract
Prenatal diagnosis of tetralogy of Fallot remains less frequent compared to other major congenital heart defects. In this study, we examined how often the 3-vessel and trachea view was abnormal in a large series of prenatally diagnosed cases of tetralogy of Fallot. In addition, we compared its sensitivity to that of the traditional outflow tract views for detection of tetralogy of Fallot. We found that both views were abnormal in all fetuses with tetralogy of Fallot, showing reversed aortic-to-pulmonary valve and aortic arch isthmus-to-ductus arteriosus ratios in the outflow tract and 3-vessel and trachea views, respectively. However, as a single measured marker, the enlarged aortic arch isthmus on the 3-vessel and trachea view appears to be the most sensitive for tetralogy of Fallot.

Abstract
OBJECTIVES The purpose of this study was to quantitatively assess cardiac function and biometric parameters in fetuses with a diagnosis of tetralogy of Fallot and compare them to those in healthy fetuses. METHODS Two hundred healthy fetuses and 20 fetuses with a diagnosis of classic tetralogy of Fallot were quantitatively assessed for 16 cardiac parameters, including morphologic characteristics and functions. All recruited fetuses were in the second trimester with correct gestational ages. The measured values that were out of normal reference ranges were considered abnormal. Rates of abnormalities of these parameters were compared between the groups. The significant parameters were further analyzed for their sensitivity, specificity, and likelihood ratio. RESULTS Of the 16 parameters, rates of abnormalities in 7 parameters, including right ventricular wall thickness, peak systolic velocities (PSVs) in the pulmonary artery and aorta, time to peak velocity, or acceleration time, in the pulmonary artery, aortic valve diameter, pulmonary valve diameter, and aortic-to-pulmonary valve diameter ratio, were significantly higher in fetuses with tetralogy of Fallot (P < .001). The pulmonary artery PSV, pulmonary artery time to peak velocity, aortic valve diameter, pulmonary valve diameter, and aortic-to-pulmonary valve diameter ratio had high sensitivities (80.0%, 75.0%, 90.0%, 90.0%, and 100.0%, respectively) and specificities (95.5%, 97.0%, 94.5%, 96.0%, and 84.5%). CONCLUSIONS In addition to a routine anatomic examination, quantitative assessment of fetal hemodynamics, especially an abnormally high PSV in the pulmonary artery, as well as a shortened acceleration time and abnormal valve size, might be very helpful for confirmation of the diagnosis in cases of suspected tetralogy of Fallot.

Prenatal and Postnatal Survival of Fetal Tetralogy of Fallot: A Meta-analysis of Perinatal Outcomes and Associated Genetic Disorders. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2016; 35:905-915.

Abstract
OBJECTIVES The aim of this systematic review was to compare the postnatal outcomes, genetic testing results, and sonographic findings in 3 subtypes of tetralogy of Fallot. METHODS Thirty-six articles from the MEDLINE and EMBASE databases were selected for this review. The postnatal outcomes, karyotyping results, and sonographic findings of fetal tetralogy of Fallot with pulmonary stenosis, tetralogy of Fallot with pulmonary atresia, and tetralogy of Fallot with an absent pulmonary valve were collected and compared. RESULTS The survival rates (termination of pregnancy was considered fetal death) for prenatally diagnosed tetralogy of Fallot with pulmonary atresia and tetralogy of Fallot with an absent pulmonary valve at the end of neonatal period were significantly lower than the rate for tetralogy of Fallot with pulmonary stenosis (P < .05). The survival rate for tetralogy of Fallot with pulmonary atresia was also lower at birth (P < .001). Major chromosomal anomalies were more frequently detected in tetralogy of Fallot with pulmonary stenosis (P< .05); conversely, 22q11 deletion was present more often in fetuses with tetralogy of Fallot with pulmonary atresia and tetralogy of Fallot with an absent pulmonary valve (P < .001). Compared to tetralogy of Fallot with pulmonary stenosis, a right aortic arch was more associated with tetralogy of Fallot with pulmonary atresia (32.6%; P < .05), and the ductus arteriosus was almost always absent in tetralogy of Fallot with an absent pulmonary valve (87.5%; P < .001). CONCLUSIONS The postnatal outcomes, genetic testing results, and sonographic findings are different among subtypes of tetralogy of Fallot. Documenting those details at diagnosis can help specialists better counsel their patients.
