“…Only isolated cases of APW in association with TOF have been described in the literature [8][9][10][11][12][13][14]. Just 40 cases of APW have been detected prenatally, and among them, the combination with TOF was described in only 2 articles (Table 1) [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34].…”

Aortopulmonary window (APW) is a rare congenital cardiac anomaly characterised by abnormal communication between the aorta and the pulmonary trunk in the presence of separately formed semilunar valves. We present a case that was initially diagnosed in prenatal life at 21 weeks as common arterial trunk. Follow-up scans starting from 31 weeks revealed APW type I in the setting of tetralogy of Fallot (S, D, S) with a right-sided aortic arch with wide interatrial communication. The neonate was born at 38 weeks of gestation by caesarean section; its birth weight was 2825 g. The postnatal echocardiogram confirmed the prenatal diagnosis provided later in gestation. Three weeks after birth, the child was scheduled for surgery: complete repair and APW closure using an autologous pericardial patch, excision of trabeculae in the right ventricular outflow tract (RVOT), transannular reconstruction below the RVOT, reconstruction of the RVOT, and partial ASD closure. The child was discharged from the hospital, weighing 3300 g, with 97% saturation. APW may remain undiagnosed until adulthood. A late diagnosis may result in congestive heart failure and irreversible damage to the pulmonary vessels. Early detection of APW, preferably in the prenatal period, remains the key issue in terms of this condition.

“…Although the source of LA blood ow in fetuses differs from that in adults, there are still three phases: the reservoir phase, conduit phase, and contraction phase, which are the same as in adults. Another aspect that differs from adults is that LV lling seems to be more dependent on atrial contraction [11,12], and, thus greater attention has been paid to the role of the atrium in fetal heart development.…”

Introduction: Fetal echocardiography is a valuable diagnostic tool for evaluating the structure and function of the fetal heart. However, assessing fetal left atrial (LA) function in various phases remains challenging, and the relationship between fetal LA and diastolic function is unknown. We used two-dimensional speckle-tracking echocardiography (2D-STE) to assess LA function in healthy fetuses in different stages and evaluated the relationship between fetal LA function and diastolic function. Materials and methods This single-center prospective study included 225 healthy women with normal singleton pregnancies. At three gestational ages, 23–24 weeks, 32–33 weeks, and 36–37 weeks, 2D-STE was performed to obtain the LA strain and strain rate in the reservoir, conduit, and contraction phases. Parameters of left ventricular (LV) diastolic function, including global longitudinal early peak LV strain rate, global longitudinal late peak LV strain rate, diastolic strain rate e/a ratio, and mitral Doppler inflow pattern E/A ratio were measured and correlated with LA strain parameters. Results Of the 225 cases, 198 (88%) were included in the analysis. Compared with measurements in the second trimester, during the third trimester, both LA strain and strain rate were lower during the reservoir and contraction phases, while the LA strain was more significant during the conduit phase (all p < 0.05). The LA strain and strain rate in the contraction phase showed a significant correlation with the parameters of LV diastolic function. Conclusions Our study findings suggest that LA contraction function correlates strongly with LV diastolic function in fetuses. Thus, monitoring changes in atrial function throughout gestation can be valuable for assessing fetal cardiac maturation and identifying abnormal fetal cardiac position.

Objectives Right atrium and left atrium of the fetal heart play a fundamental role in fetal heart circulatory physiology. Methods Excursion of fetal atria walls and tracings of foramen ovale (FO) flap movement were analyzed by M-mode echocardiography by new FO index to determine fetal and neonatal outcome in the first week and month of life in various congenital heart defects. The study group was divided into 3 subgroups: group A: neonates stable after birth (all on I.V. prostaglandin infusion) for at least 7 days, group B: neonates unstable after birth (despite I.V. prostaglandin infusion) requiring catheterization procedure or early cardiac surgery <6th day of life and group C: fetuses with in utero demise. Results The average values of FO index: group A – 32, group B – 20, group C – 12.Schaffe test showed statistical difference of FO index between group A and B (p=0.029) and group A and C (p=0.001), but no difference between group B and C (p=0.24) The FO index of stability was determined by ROC curve analysis. Cut-off point distinguishing between postnatal stability and postnatal instability + in utero demise constituted FO index=25 (specificity 82%; sensitivity 90%). Conclusions Prenatal features of atrial M-mode echocardiography shortly before birth might be helpful to predict the short term prognosis of fetal hemodynamic stability or instability shortly after birth regardless of the type of congenital heart defects (CHD).
