Atrial fibrillation (AF) is a really uncommon arrhythmia in newborns. Here, we report the case of a 1-day-old infant who was recovered in Neonatal Intensive Care Unit for a twin-to-twin transfusion. The appearance of an unexpected AF was registered at his continuous electrocardiographic monitoring. Both chest X-ray and echocardiographic examination revealed the anomalous insertion of the tip of a central venous catheter (CVC) into the heart ('umbilical artery → inferior vena cava → right atrium → patent foramen ovale → left atrium')...

BACKGROUND: The efficacy of antenatal corticosteroid treatment for women with threatened preterm birth depends on timely administration within 7 days before delivery. We modelled the probability of delivery within 7 days of admission to hospital among women presenting with threatened preterm birth, using routinely collected clinical characteristics. METHODS: Data from the Canadian Perinatal Network (CPN) were used, 2005-11, including women admitted to hospital with preterm labour, preterm pre-labour rupture of membranes, short cervix without contractions, or dilated cervix or prolapsed membranes without contractions at preterm gestation...

OBJECTIVE: To analyze monochorionic twin pregnancies with twin anemia polycythemia sequence (TAPS) and acute peripartal twin to twin syndrome (aTTTS), to compare their prenatal management and perinatal outcome. METHODS: Retrospective analysis of monochorionic biamniotic twin pregnancies without signs of chronic TTTS within a period 10/2010 to 10/2013. Further selection of cases with haemoglobin difference in neonates greater than 50 g/l was made, type of feto-fetal haemorrhage was determined and their prenatal and postnatal characteristics were described...

AIM OF THE STUDY: The hemodynamic imbalance due to placental vascular anastomoses in TTTS but also vascular changes generated after intrauterine treatment may lead to hypoxic-ischemic complications. Different intestinal complications in TTTS are reviewed in this paper. METHODS: Retrospective review of TTTS cases treated by laser coagulation (LC) from 2012-2015. Demographic data, fetal therapy, prenatal diagnosis (US, MRI) and perinatal outcome were recorded. We describe cases with intestinal complications and their postnatal management...

Twin-twin transfusion syndrome is a complication of monochorionic-diamniotic placentation. Should one twin die, ≈30% of co-twins will also die, and if they survive, ≈30% experience severe morbidity rates, each believed secondary to hemorrhage of the co-twin into the deceased twin. We report apparently the first ultrasound-documented case of perimortem hemorrhage in twin-twin transfusion syndrome and its treatment by emergent ultrasound-guided percutaneous cord occlusion followed by percutaneous fetal intravascular transfusion...

To evaluate the relative risk of placental abruption in monochorionic (MC) twin pregnancies complicated with twin-to-twin transfusion syndrome (TTTS) and treated with endoscopic laser coagulation of placental vessels (ELCPV). A retrospective analysis from January 2004 and December 2015 of 373 TTTS pregnancies, treated with selective ELCPV until January 2012 (287 cases), after which the Solomon technique was introduced (86 cases), compared with 243 normal MC pregnancies. A significant improvement in perinatal survival was observed after the introduction of the Solomon technique when compared to the selective procedure (77% vs 54%, p < 0...

Dizygotic monochorionic twin pregnancies can result in blood chimerism due to in utero twin-to-twin exchange of stem cells. In this case, we examined the proportion of allogeneic red blood cells by flow cytometry and the proportion of allogeneic nucleated cells by digital polymerase chain reaction at 7 months and again at 5 years. We found an increase in the proportion of allogeneic cells from 63% to 89% in one twin, and a similar increase in autologous cells in the other twin from 57% to 84%. A paradigm for stem cell therapy could be modeled on this case: induction of tolerance and chimerism by antenatal transfusion of donor stem cells...

Solid organ transplantation in pediatric patients has been a reality since 1954, when the first kidney transplantation was successfully performed between identical twins. We report the long-term outcomes, with more than 25 years of follow-up, in a patient born with hypoplastic left heart syndrome (HLHS) who received a heart transplant from a dizygotic twin. While we would not wish for this situation to reoccur, we hope that in reporting it, we can add to the discussion surrounding pediatric heart transplantation and the management of HLHS...

We have developed a calibration target for use with fluid-immersed endoscopes within the context of the GIFT-Surg (Guided Instrumentation for Fetal Therapy and Surgery) project. One of the aims of this project is to engineer novel, real-time image processing methods for intra-operative use in the treatment of congenital birth defects, such as spina bifida and the twin-to-twin transfusion syndrome. The developed target allows for the sterility-preserving optical distortion calibration of endoscopes within a few minutes...

Twin-to-twin transfusion syndrome (TTTS) at times complicates monochorionic twin gestations, resulting in conditions ranging from discordant sizes to fetal demise of one baby. Various types of cardiac defects have been described in the recipient twin of this syndrome. Isolated great artery calcification, i.e. aortic and pulmonary artery calcification is one such uncommon condition associated with TTTS. Calcification of the walls of great vessels may be due to chronic vascular injury sustained as a result of circulatory volume overload in the recipient twin...

Twin-to-twin transfusion syndrome (TTTS) complicates 10% of monochorionic twin pregnancies and it is consequence of an unbalanced exchange blood through the vascular anastomoses at placental surface. If not treated, mortality rates in TTTS may be as high as 80-100%. Laser photocoagulation of the placental anastomoses is the first treatment option; however, in some situations, the damage of the placenta in the postpartum may become difficult the residual anastomoses identification. We propose a new non-invasive technique to assess the residual anastomoses using computed tomography (CT) scan data to generate a three-dimensional (3D) virtual placentoscopy...

The early diagnosis of the Twin-To-Twin transfusion syndrome (TTTS) carries benefits of the better survivor for the fetus-donor; but at the same time there are obvious practical impediments to diagnose the condition earlier in the course of a pregnancy. That's why this particular problem in practical medicine requires in depth investigation to clarify casual factors, and specify tactical approach to the prospective patients which in turn will lead to prevention of the fetal death and damage and improvement of fetal survivor in any form of TTTS...

INTRODUCTION AND OBJECTIVES: Many international studies have demonstrated that delayed umbilical cord clamping reduces neonatal morbidity. However, in France, delayed umbilical cord clamping is still not performed in many neonatal units. The aims of this study were to evaluate the feasibility of developing a protocol of delayed umbilical cord clamping in the maternity ward of the Toulouse university hospital and to evaluate the impact of this new protocol on neonatal mortality. METHODS: We conducted a prospective observational study including 123 preterm infants born before 37 weeks of gestation between June 2012 and June 2013 and hospitalized at birth...

BACKGROUND AND AIMS: Twin pregnancy with monochorionic placenta may be associated with arteriovenous vascular anastomosis of the placental vessels resulting in twin-to-twin transfusion syndrome (TTTS) and twin reversed arterial perfusion syndrome (TRAP). Foetoscopic LASER ablation (FLA) is the treatment of choice in reducing foetal mortality related to this. METHODS: A retrospective review of medical records of 41 FLA procedures for TTTS and TRAP were analysed for anaesthetic management...

A monochorionic-diamniotic twin baby presented with intrauterine growth restriction and anuria. The baby was found to have bladder agenesis, a pelvic dysplastic horseshoe kidney, vertebral anomalies, a ventricular septal defect and facial dysmorphisms. It was surprising to find no abnormalities in amniotic fluid indices prenatally, suggesting the possibility of urine output that declined as the pregnancy proceeded. Some degree of twin-to-twin transfusion of amniotic fluid was also possible, which could have rescued the oligohydramnios known to be associated with kidney and urinary tract abnormalities...

The aim of this study was to determine the effects of intrauterine environment on the magnitude of intrapair differences in six somatic traits of monozygotic (MZ) and dizygotic (DZ) twins (1,263 pairs; 424 MZ twins and 839 DZ twins). Differences in intrauterine environments of MZ twins enforced division of the research material into four groups: (1) MZ-MC-TTTS - MZ twins from monochorionic (MC) pregnancies with twin-to-twin transfusion syndrome (TTTS), (2) MZ-MC (without TTTS)-MZ twins from MC pregnancies without TTTS, (3) MZ-DC-MZ twins from dichorionic (DC) pregnancies, and (4) DZ-DZ twins...
