Feridoun Sabzi, Aghigh Heidari
Prepartum or postpartum right ventricular thrombosis (RVT) is an exceedingly rare and potentially lethal phenomenon in pregnancy. We here report a case of a pregnant patient with near term pregnancy admitted for dyspnea, amniotic fluids discharge and labor pain in a gynecology center that an eight-month dead fetus was diagnosed and delivered vaginally by induction. A post delivery period was complicated by aggravation of her dyspnea and pleuritic chest pain that she referred for further evaluation in our cardiac center...

Importance: Fetal umbilical vein aneurysm is an uncommon anomaly that accounts for approximately 4% of umbilical cord abnormalities. The rate of intrauterine fetal death is reported to be approximately 4% to 5%, higher than the background rate of 0.7% that is generally reported during pregnancy. Objective: The aim of this study was to review the pathophysiology, diagnosis, and clinical management of fetal umbilical vein aneurysm. Evidence Acquisition: Advances in high-resolution ultrasound combined with color Doppler and 3-dimensional rendering have contributed to an increased understanding of the fetal venous circulation in recent years...

Fetal Cardiology. Experiences from a tertiary referral centre in Stockholm, Sweden This review provides a brief overview of the current position and clinical experiences of fetal cardiology at a tertiary referral centre in Stockholm, Sweden. In Stockholm, more than 60% of congenital cardiac defects requiring surgery or catheter intervention before one year of age are detected before birth. This not only results in termination of pregnancy in the majority of cases carrying a poor prognosis, but also conveys a better postnatal care and prognosis in cases of continued pregnancy...

BACKGROUND: Tuberous sclerosis, also known as tuberous sclerosis complex (TSC), is a rare genetic condition that mainly causes hamartomas to develop in different parts of the body. TSC, an autosomal dominant trait with variable penetrance, can adversely affect maternal and fetal outcome. CASE PRESENTATION: In this paper, a case of maternal and fetal tuberous sclerosis having fetal cardiac rhabdomyoma detected in utero at 26 weeks was reported who subsequently had fetal demise at 31 weeks...

Total anomalous pulmonary venous connection (TAPVC) is a rare form of cyanotic congenital heart disease (CHD) that occurs when the pulmonary veins drain into a site other than the morphologic left atrium. As with other forms of CHD, TAPVC has been shown to cluster in families and is known to have genetic association. We report on a case series of familial TAPVC in three consecutive siblings. A combination of fetal echocardiography, transthoracic echocardiography, as well as cross-sectional imaging was utilized in the diagnosis as well as management of each sibling...

REVIEW
Aleksander Sizarov, Younes Boudjemline
Efficient use of fetal echocardiography has enabled early detection of congenital heart disease and of its often irreversible complications, such as ventricular hypoplasia in case of severe stenosis of the semilunar valves. Experience of the past 25 years has proved that balloon dilatation of the severely stenotic or atretic valve in fetuses as early as the 23rd week of gestation is technically feasible with a learning curve. Reported results regarding the ultimate biventricular circulation outcome after fetal valve intervention are at best controversial, with the desired improvements in the quality of life and cost-benefits of the postnatal treatment being as yet unconfirmed...

Hyperglycemia is an independent risk factor for diabetic cardiomyopathy in humans; however, the underlying mechanisms have not been thoroughly elucidated. Zebrafish (Danio rerio) was used in this study as a novel vertebrate model to explore the signaling pathways of human adult cardiomyopathy. Hyperglycemia was induced by alternately immersing adult zebrafish in a glucose solution or water. The hyperglycemic fish gradually exhibited some hallmarks of cardiomyopathy such as myocardial hypertrophy and apoptosis, myofibril loss, fetal gene reactivation, and severe arrhythmia...

OBJECTIVE: To evaluate segmental left (LV-S) and right (RV-S) ventricular strain as well as longitudinal mechanical myocardial dyssynchrony as a time difference between peaks in strain of both ventricles in fetuses (two-chamber-dyssynchrony, 2C-DYS) using speckle tracking echocardiography (STE). The aim of our study was to evaluate the influence of data acquisition on the results of STE measurement using different ultrasound probes. METHODS: We prospectively recorded cardiac cycles of four-chamber views of 56 normal fetuses with three different ultrasound probes and analyzed them offline with speckle tracking imaging software...

Intrauterine growth restriction in animal models reduces heart size and cardiomyocyte number at birth. Such incomplete cardiomyocyte endowment is believed to increase susceptibility toward cardiovascular disease in adulthood, a phenomenon referred to as developmental programming. We have previously described a mouse model of impaired myocardial development leading to a 25% reduction of cardiomyocyte number in neonates. This study investigated the response of these hypoplastic hearts to pressure overload in adulthood, applied by abdominal aortic constriction (AAC)...

Depression is generally treated with antidepressants, but may often need antipsychotics and mood stabilizers. We discuss the updated data regarding the safety in pregnancy of antidepressants and antipsychotics, except selective serotonin reuptake inhibitors, and their possible impact on the long-term development of the offspring. Several earlier studies demonstrated a slight increase in the rate of major anomalies following maternal tricyclic antidepressant treatment, but most current literature shows their relative safety in pregnancy...

REVIEW
Hyun Suk Yang
Congenital heart disease (CHD) is now more common in adults than in children due to improvements in fetal echo, neonatal and pediatric care, and surgical techniques leading to dramatically increased survivability into adulthood. Adult patients with CHD, regardless of prior cardiac surgery, experience further cardiac problems or therapeutic challenges; therefore, a non-invasive, easily accessible echocardiographic examination is an essential follow-up tool. Among echocardiographic modalities, three-dimensional (3D) echocardiography provides better delineation of spatial relationships in complex cardiac geometries and more accurate volumetric information without geometric assumptions...

Here we report a case of fetal left ventricular non-compaction cardiomyopathy with ascites and cardiac dysfunction at a gestational age of 34(+5)  weeks. Laboratory tests did not reveal any sign of viral infection in utero. A female neonate weighing 2436 g was delivered by emergency cesarean section due to non-reassuring fetal status. Postnatal echocardiography confirmed left ventricular non-compaction cardiomyopathy with severe cardiac failure. Although she was treated effectively during the acute period by continuous flow peritoneal dialysis, surgical ligation of a patent ductus arteriosus, and inhaled nitric oxide, she died on day 41 of life...
