Abstract
Introduction: Prenatal atrioventricular septal defect (AVSD) on frequent occasions coexists with other cardiac or extracardiac abnormalities or malformation which may change the prognosis and the management with the fetus and the newborn. The aim of the research was to assess the prognosis and the outcome of prenatally diagnosed AVSD based on the classification which also includes coexisting extracardiac abnormalities and malformations as well as its influence on the prenatal consultation.Methods: It was a retrospective analysis of 113 patients with prenatally diagnosed AVSD. The group was selected out of 871 patients with CHD. Out of 113 fetuses with AVSD we exclude those in whom AVSD was coexistent with other cardiac malformations (n = 41). Extracardiac abnormalities [ECA] were defined as problems which do not require surgical intervention after delivery, they were usually markers of a genetic syndrome. Extracardiac malformations [ECM] were defined as problems requiring surgical interventions after delivery or lethal malformations. All 72 fetuses with an isolated AVSD were classified to one of the three groups: (1) Simple AVSD - (sAVSD) - a fetus with isolated AVSD without coexisting ECA and ECM (n = 6), (2) sAVSD + ECA - a fetus with isolated AVSD, with coexisting ECA (n = 28), (3) sAVSD + ECM - a fetus with isolated AVSD, with coexisting ECM (n = 38).Results: The pregnancy from the groups sAVSD + ECM were, in fact, more often referred to the prenatal cardiology centers on account of the existing ECM (p=.03). There were no differences between the two subgroups in regard to: the mean age of the pregnancy, the mean age of the fetus at the time of diagnosis and during diagnostic testing at the referral center, the gender of the fetus. An increased nuchal translucency (NT) was most often found in fetuses from the group AVSD + ECA (n = 13/23), which was connected with more frequent occurrence of abnormal karyotype (p=.048). The trisomy 21 more frequently referred to pregnancy with sAVSD + ECA than those with sAVSD + ECM (p=.0006). In the group sAVSD + ECM there was the highest number of fetuses small for the gestational age detected -48.65% (p=.01). Most often premature deliveries were found in the group sAVSD + ECM (72.73%). The duration of gestation in the group sAVSD + ECM turned out to be much shorter than that in the group with the isolated sAVSD (p=.01) and sAVSD + ECA (p=.03). The lowest Apgar score was in the newborns from the group sAVSD + ECM (p=.002). Longer period of gestation was connected with the higher score on Apgar scale (R = 0.541; p=.001). The average delivery weight of the newborns was the lowest in the group sAVSD + ECM (p=.04). sAVSD + ECM was connected with the significantly higher death rate than the isolated sAVSD (p=.0047) or sAVSD + ECA (p<.00001). The fatality rate of the newborns/ fetuses from the pregnancies lasting less than 37 weeks turned out to be much higher than in the case of the remaining pregnancies (sAVSD p=.002).Conclusions: (1) The majority of fetuses with AVSD remained the patients of just obstetricians and prenatal cardiologists because of highly heterogeneous of the coexisting malformations and abnormalities and since they perish in the period of fetal or neonatal life usually they are not seen by the pediatricians or cardiac surgeons. (2) The classification of the AVSD in fetus to a particular group of the prognostic classification of the fetal heart defects helps to plan perinatal management and supplies information regarding the prognosis. (3) The highest mortality rate was in a group of AVSD + ECM, probably due to shorter time of pregnancy duration, fetuses grow restriction and low Apgar score in 1 minute of life.

Spontaneous Left Cardiac Isomerism in Chick Embryos: Case Report, Review of the Literature, and Possible Significance for the Understanding of Ventricular Non-Compaction Cardiomyopathy in the Setting of Human Heterotaxy Syndromes. J Cardiovasc Dev Dis 2019; 6:jcdd6040040.

Abstract
The outer shape of most vertebrates is normally characterized by bilateral symmetry. The inner organs, on the other hand, are normally arranged in bilaterally asymmetric patterns. Congenital deviations from the normal organ asymmetry can occur in the form of mirror imagery of the normal arrangement (situs inversus), or in the form of arrangements that have the tendency for the development of bilateral symmetry, either in a pattern of bilateral left-sidedness (left isomerism) or bilateral right-sidedness (right isomerism). The latter two forms of visceral situs anomalies are called “heterotaxy syndromes”. During the past 30 years, remarkable progress has been made in uncovering the genetic etiology of heterotaxy syndromes. However, the pathogenetic mechanisms causing the spectrum of cardiovascular defects found in these syndromes remain poorly understood. In the present report, a spontaneous case of left cardiac isomerism found in an HH-stage 23 chick embryo is described. The observations made in this case confirmed the existence of molecular isomerism in the ventricular chambers previously noted in mouse models. They, furthermore, suggest that hearts with left cardiac isomerism may have the tendency for the development of non-compaction cardiomyopathy caused by defective development of the proepicardium.

Abstract
Left ventricular hypertrabeculation/noncompaction (LVHT) is a cardiac abnormality of unknown etiology. Prenatal diagnosis of LVHT can be established by fetal echocardiography. A review of 106 published cases showed that 46 cases with prenatally diagnosed LVHT were alive 0.5-120 months after birth. Since the course of cases with prenatally LVHT after publication is unknown, we aimed to collect follow-up-information. Information regarding vital status, cardiac and extracardiac morbidity was gathered by contacting the authors of the 46 cases. Fourteen of the 28 authors answered and gave information about 18 cases (six females, seven males, five gender-unknown, age 18 months to 10 years, mean follow-up 60 months). No differences were found between the 18 cases with follow-up and the 28 cases without follow-up regarding age, gender, cardiac or extracardiac comorbidities, and interventions. Three of the 18 cases had died subsequently from heart failure, osteosarcoma, and enterocolitis, respectively. Mutations or chromosomal abnormalities were found in six of the seven examined patients, extracardiac abnormalities in nine patients. Three patients received a pacemaker because of complete AV block, and two patients underwent heart transplantation. Cardiac surgical or interventional procedures were carried out in four patients. None suffered from malignant arrhythmias or had a cardioverter-defibrillator implanted. Based on the limited information, there are indications that cases with fetal diagnosis of LVHT have a continuing morbidity and mortality, even if they receive appropriate care. Since fetal LVHT is frequently associated with genetic abnormalities, further research about survival and underlying genetic causes is needed.

Abstract
Left ventricular hypertrabeculation/noncompaction (LVHT) is a cardiac abnormality of unknown etiology. Aim of the review was to summarize the current knowledge about fetal LVHT, including clinical presentation, associated cardiac and extracardiac abnormalities and outcome. In 88 cases, LVHT was diagnosed by fetal echocardiography. In 36 %, no additional cardiac abnormalities were reported; in the remaining 64 %, one or more cardiac abnormalities were reported. Eight cases died prenatally, 17 were electively terminated, and 24 patients died after birth. Six patients were lost to follow-up, and 33 patients are alive at a mean age of 26 months. Surviving cases presented less frequently with fetal hydrops (13 vs. 62 %, p = 0.0004), complete heart block (27 vs. 78 %, p = 0.0076), more than three associated cardiac abnormalities (9 vs. 47 %, p = 0.0008) and more frequently with isolated LVHT (52 vs. 19 %, p = 0.009) than cases who died. Of the surviving patients, 16 received pharmacotherapy, three received pacemakers, eight underwent surgical procedures and four underwent heart transplantation. Postnatal regression of left ventricular hypertrophy and development of LVHT was found in four cases, improvement in cardiac function in two, and regression of right VHT in two. At autopsy, endocardial fibrosis was the most frequent abnormality in 92 %. Thirty-eight percentage of cases with fetal LVHT survived. Fetal and postnatal echocardiographic findings challenge the "embryonic pathogenetic" hypothesis of LVHT. Furthermore, fetal pathoanatomic findings like endocardial fibrosis might play a role in clarifying the still unsolved pathogenesis of LVHT.
