A case was reported of a fetus with the anomaly of limb body wall complex associated with placenta accreta. To date, only one account of this condition has been published in the world literature. Due to the low frequency of both complications, the hypothesis has been raised that this association may have happened not by mere coincidence, but rather by a possible common etiopathogenic mechanism. For the first time, a study proposes the existence of a possible etiopathogenic connection between the anomaly of limb body wall complex and hypoxic disorders caused by inadequate placentation in previous uterine scarring.

PURPOSE: to analyze the differential diagnosis, follow-up and therapeutic approach in five cases of primary cardiac tumors diagnosed during the prenatal period. METHODS: during the period from January 1997 to December 2008, 7989 pregnant women were submitted to morphological ultrasound due to the presence of risk factors for fetal malformations. Fetuses with hyperechogenic intracardiac masses larger than 1 mm diagnosed by ultrasound evaluation of the fetal heart, were selected for study. The differential diagnosis between the different tumor types was made on the basis of the ultrasound characteristics of the masses. RESULTS: five fetuses with hiperechogenic intracardiac masses were diagnosed, corresponding to a 0.06% prevalence rate. Gestational age ranged from 28 to 36 weeks (mean: 31), and maternal age ranged from 23 to 45 years (mean: 34,2). The most frequent location of the masses was the left ventricle (100%). Echographically, all masses were single or multiple, hyperechogenic, homogeneous and well delimited, compatible with a diagnosis of rhabomyoma. In cases in which the diameters of the masses were less than 20 mm, an expectant conduct was followed and no complications occurred during the prenatal period. One case with a huge tumor presented arrhythmia and cardiac insufficiency during the 35 gestational weeks, and the interruption of pregnancy was indicated. Tuberous sclerosis was associated in four cases (80%) and the diagnosis was confirmed during the postnatal follow-up. CONCLUSIONS: fetal morphological ultrasonography is the main form of early detection of primary cardiac tumors. The fetal cardiac evaluation is of fundamental importance for the differential morphological characterization of cardiac masses and for the evaluation of cardiac function. Rhabdomyomas are the most common type of fetal tumor. An expectant pre and postnatal conduct is followed, with a low risk of complications and with the possibility of spontaneous regression in most cases. Postnatal clinical follow-up is mandatory due to the high frequency of associated tuberous sclerosis.

PURPOSE: to analyze the results of a screening and diagnostic program of arrhythmias and congenital heart disease in a reference hospital and the relevance of early diagnosis in the fetal and neonate evolution. METHODS: cardiac evaluation of 1159 fetuses was done in two different levels. Level I: by morphological ultrasound examination with the objective to detect the existence of either arrhythmias or structural cardiac malformations. Level II: by fetal echocardiography to establish the differential diagnosis. The results of level I in the arrhythmia group were compared with those of level II, and in the group with malformations the results of both levels were confronted with the neonate echocardiogram or necropsy. The kappa index was calculated to evaluate the concordance between the two levels. RESULTS: all detected arrhythmias in level I were confirmed in level II, there were no false negative cases and five patients with severe arrhythmia required pharmacological therapy. The diagnosis of structural malformation by level I had sensitivity of 72% and specificity of 98% and there were 28% of false-positive cases. In level II, the sensitivity and specificity of the diagnosis of congenital heart disease were 100 and 99%, respectively. The kappa index was 57% and indicated a moderate degree of concordance between the two levels. Fifty-one percent of the fetuses with diagnosis of cardiac malformations required pharmacological or invasive intervention immediately after birth. CONCLUSION: morphological ultrasound examination is a important tool in the screening of arrhythmias and congenital heart defects during fetal life. The sensitivity and specificity of the fetal echocardiogram were very high and the early diagnosis made it possible to treat the fetus with severe cardiac disease either during pregnancy or immediately after birth.
