BACKGROUND: Monochorionic diamniotic (MCDA) twin pregnancies are associated with adverse perinatal outcome. Intertwin discordances at the time of nuchal translucency (NT) screening may have a value in the prediction of fetal loss or twin-to-twin transfusion syndrome. We aimed to determine the ability of intertwin NT and crown rump length (CRL) discordances among MCDA twins to predict adverse outcomes. MATERIAL AND METHODS: All MCDA twins with a documented routine ultrasound at 11 to 13+6 weeks' gestation, and known pregnancy outcome between August 2003 and August 2012 were included...

INTRODUCTION: Twin-twin transfusion syndrome (TTTS) is the major cause for fetal demise in monochorionic diamniotic pregnancies. Estimated combined cardiac output (CCO) has not been studied in this setting. The primary aims of this study were to compare CCO in twin donor and recipient fetuses and assess differences in CCO before and after laser coagulation therapy. A secondary aim was to evaluate the relationship of CCO with perinatal mortality, defined as intrauterine or neonatal mortality (≤30 days of age) in fetuses that underwent laser coagulation therapy...

Circulating nucleic acids have revolutionized prenatal diagnosis in the last decade, allowing non-invasive screening for single gene or chromosomal defects using a single sample of maternal blood. In addition to deoxyribonucleic acids (DNA), ribonucleic acids (RNA) from the placenta are released into the maternal blood from early in pregnancy and may reflect changes in gene expression occurring within the placenta. Measuring circulating RNA may therefore provide insights into the placental transcriptome without the need for invasive testing...

OBJECTIVES: Amniopatch is a proposed treatment of iatrogenic preterm premature rupture of membranes (iPPROM). We studied characteristics associated with successful amniopatch treatment of iPPROM after fetoscopic laser surgery for twin-twin transfusion syndrome. METHODS: Patients with iPPROM within 15 days of laser surgery treated with an amniopatch were studied. Factors associated with amniopatch success (i.e. cessation of leakage with normalization of amniotic fluid volume) were tested univariately and in multivariate logistic regression models...

BACKGROUND: Acardiac monochorionic twins lack cardiac function but grow by passive perfusion of the pump twin's deoxygenated arterial blood through placental arterioarterial (AA) and venovenous (VV) anastomoses and by hypoxia-mediated neovascularization. Pump twins therefore must continuously increase their cardiac output which may cause heart failure. Our aims were: to adapt our twin-twin transfusion syndrome model for acardiac twin pregnancies, to simulate pump and acardiac twin development, and to examine the model for early prognostic markers of pump twin survival...

Monochorionic multiple pregnancy has a higher risk for obstetric complications, including those due to the development of twin-to-twin transfusion syndrome and reversed arterial perfusion syndrome (TRAP sequence). The latter occurs in 0.1% of all monochorionic pregnancies. The basis for TRAP sequence is a relationship between arterial and venous anastomoses from the appropriate placental areas, causing a recipient fetus to develop at the expense of a donor fetus. The presence of abnormal anastomoses is considered to be a main cause of acardia...

Twin anemia polycythemia sequence (TAPS) is defined by significant intertwin hemoglobin discordance without the amniotic fluid discordance that characterizes twin-twin-transfusion syndrome (TTTS) in monochorionic twin pregnancies. TAPS is an uncommon condition which can either occur spontaneously, or following fetoscopic laser ablation for TTTS. This complication is thought to result from chronic transfusion through very small placental anastomoses; however, the pathogenesis of TAPS remains unknown. Consequently, there is no consensus in the management of TAPS...

INTRODUCTION: Monochorionic-diamniotic (MCDA) twin pregnancies are high risk, due to twin-to-twin transfusion syndrome (TTTS), twin anaemia polycythaemia sequence (TAPS) and intrauterine growth restriction (IUGR). There is limited evidence to guide ultrasound surveillance protocols. Using a retrospective cohort, we aimed to provide insight into the optimal interval of ultrasound surveillance. METHODS: Retrospective cohort of women with MCDA pregnancies who received antenatal care at Monash Medical Centre (January 2011-October 2014)...

OBJECTIVE: To evaluate the rate of pulmonary stenosis and functional pulmonary atresia (PS/PA) in recipient twins prior to fetal surgery for twin-twin transfusion syndrome (TTTS) and their pre- and postnatal outcomes. METHODS: We carried out a prospective study including 260 cases of TTTS. Echocardiography was performed before laser surgery to detect the presence of PS/PA. The outcomes of recipients with and without PS/PA were compared. The need of postnatal cardiac interventions and the survival rate at 6 months of age were also evaluated...

INTRODUCTION: Twin-twin transfusion syndrome (TTTS) complicates 15% of monochorionic twin pregnancies, often being associated with recipient cardiac dysfunction. Untreated, it has a fetal mortality rate of at least 90%; although treatment by fetoscopic laser coagulation significantly improves prognosis. Measurement of recipient amniotic fluid metabolites, such as cardiac Troponin T and atrial natriuretic polypeptide, correlate with cardiac function in this fetus. The aim of this study is to describe the amniotic fluid metabolomic profile in TTTS, relate this to fetal recipient cardiac function and assess the metabolomic changes induced by fetoscopic laser coagulation...

INTRODUCTION: Management of complicated monochorionic twins and certain intrauterine structural anomalies is a pressing challenge in communities still lacking advanced fetal therapy. We describe our efforts to rapidly initiate selective feticide using radiofrequency ablation (RFA) and selective fetoscopic laser photocoagulation (SFLP) for twin-twin transfusion syndrome (TTTS) and present the latter as a potential model for aspiring fetal therapy units. METHODS: Five pregnancies with fetal complications were identified for RFA...

Two-dimensional (2D) and Doppler echocardiography has become both an essential component in the assessment of anatomic anomalies of the fetal heart and an important tool in the assessment of fetal cardiac function. Various techniques for assessing fetal cardiovascular function exist and can be used to characterize systolic and diastolic ventricular function and estimate fetal cardiac output. These techniques can be utilized to assess fetuses with cardiovascular compromise due to a number of cardiac and non-cardiac conditions, including twin-twin transfusion syndrome, high-cardiac output lesions such as fetal tumors and vascular malformations, and primary fetal cardiomyopathy...
