Abstract
The prognosis of right heart enlargement varies according to different etiologies. The purpose of this study was to investigate the characteristics of echocardiogram, surgical treatment, chromosome and prognosis for fetal right heart enlargement.The foetal echocardiogram was performed on 3987 pregnant women, and then 88 fetuses with right heart enlargement were identified. The data about prenatal and postnatal echocardiograms, postnatal cardiac surgical treatment, karyotype analysis and autopsy after induced labor were analyzed in the 88 fetuses.Except the 1111 cases that had loss of follow-up, 2876 cases had complete data. Among the 2876 cases, right heart enlargement was identified in 88 fetuses. Of the 88 fetuses, 15 had total atrioventricular septal defect (unbalanced type: right ventricular dominance), 15 Ebstein's anomaly, 18 fallot tetrad, 14 double outlet right ventricle, 13 total anomalous pulmonary venous drainage, and 13 premature closure of ductus arteriosus. Chromosomal abnormality was found in 12 cases.There are many etiological factors causing right heart enlargement. The prognosis is better in the fetuses with single heart malformation than in the fetuses who have extracardiac malformation or/and chromosomal abnormality besides heart malformation. Fetal echocardiography combined with karyotype analysis can provide important bases for evaluating the prognosis of fetuses with right heart enlargement.

Abstract
Intrauterine echocardiography is changing our knowledge of congenital heart disease; cardiac defects diagnosed in utero have distinctive features of both prevalence and morphology when compared with those observed just after birth. We reviewed a series of 171 fetal heart conditions: 148 were diagnosed at intrauterine echocardiography, the diagnosis being verified at autopsy in 41, and 23 were observed at the postmortem only. Peculiarities of prevalence consisted in an excess of various defects, such as hypoplastic left heart syndrome, atrial isomerism, pulmonary atresia, and atrioventricular and atrial septal defects, and in a reduced number of completely different conditions, such as transposition of great arteries and aortic coarctation. Differences in prevalence have been attributed to difficulties in diagnosing some particular anomalies in utero, to the selection of pregnancies undergoing screening, and to the special intrauterine evidence of some heart defects. Peculiarities in morphology result from the coexistence with extracardiac malformations, from the changes in shape conditioned by fetal hemodynamics, and from the intrauterine evolution of the morphology of some malformations. We concluded that the knowledge of these characteristic traits was helpful to cardiac pathologists, pediatric cardiologists, and obstetricians, and allowed the re-evaluation of the role of hemodynamic factors in remodeling the malformed cardiovascular appara-tus.

Abstract
Borderline or equivocal sonographic findings in the fetal heart are occasionally encountered. Echogenic foci in the ventricles, small pericardial effusions, and mild discrepancy in ventricular size are three such problematic findings. The significance of each of these findings, as currently understood, will be discussed in this article.

Abstract
To assess ventricular diastolic filling in fetuses with constriction of ducts arterious, 43 fetuses of pregnant women receiving indomethacin (100 to 150 mg/day) were examined with Doppler echocardiography. Ductal constriction occurred in 21 fetuses, defined as maximal systolic velocity > 140 cm/s and diastolic flow velocity > 30 cm/s. The variables measured to assess diastolic function were peak velocity during early diastole (peak E wave), peak velocity during atrial contraction (peak A wave), and the velocity ratio (peak E/A ratio); these were compared to maximal ductal flow velocity during systole and diastole. The mitral peak E wave, peak A wave, and peak E/A ratio in fetuses with ductal constriction showed no significant difference from those in fetuses without ductal constriction. In fetuses with ductal constriction, the tricuspid A wave increased significantly without changes in the peak E wave (57 +/- 9 vs 50 +/- 6 cm/s, p < 0.01) and the peak E/A ratio was significantly lower than in fetuses without ductal constriction (0.57 +/- 0.10 vs 0.65 +/- 0.08, p < 0.05). In 9 fetuses with ductal constriction, we compared the Doppler tricuspid E wave, A wave, and E/A ratio during indomethacin administration with those after withdrawal of the drug for a mean of 24 hours. Both systolic and diastolic ductal flow velocities in the fetuses returned to normal range after discontinuation of indomethacin. The tricuspid peak A wave decreased (59 +/- 9 vs 50 +/- 11 cm/s) and the E/ A ratio increased significantly (0.56 +/- 0.07 vs 0.69 +/- 0.07) (both p < 0.01) without any significant change in peak E wave after discontinuation of indomethacin. This study suggests that ductal constriction influences Doppler patterns of right ventricular diastolic filling. These changes could be related to the increased afterload presented to the right ventricle which might affect diastolic function.
