Tissue Doppler Analysis of Postnatal Circulatory Dysfunction in Recipient Infants of Twin-Twin Transfusion Syndrome
نویسنده
چکیده
Methods: Out of 172 very low birth weight (VLBW) infants admitted from 2004 to 2007, five recipient infants of monochorionic diamniotic twins were defined as recipient group (n=5). Three to five control infants matched for gestational age, birth weight, gender were selected from the remaining VLBW infants in the same study period (control group, n=20). Serial echocardiographic examinations including TDI were performed from birth to days 7, then peak systolic velocities (S), early diastolic velocities (Ea), late diastolic velocities (Aa), and myocardial performance index (MPI) were measured at the lateral annulus of mitral and tricuspid valves.

Clinical and echographic features of in utero cardiac dysfunction in the recipient twin in twin-twin transfusion syndrome.
OBJECTIVE Fetal twin-twin transfusion syndrome (TTTS) presenting in the second trimester has been associated with almost no perinatal survival until recently, when serial drainage of amniotic fluid has improved the prognosis to 70%-80%. Most recipient twins now survive but develop cardiac dysfunction. The study was undertaken to evaluate the abnormal echocardiographic features and clinical comp...

OBJECTIVE To test the hypothesis that identical twins show no inter-twin differences in cardiovascular structure or physiology in fetal life unless there has been twin-twin transfusion syndrome. DESIGN Unselected prospective case-control observational study of fetoplacental haemodynamics including echocardiography at a median of 24 (16.7 to 32.3) weeks, with postnatal confirmation of congenit...
متن کاملLate-onset transient adrenal insufficiency in preterm twins with twin-to-twin transfusion syndrome
RATIONALE Late-onset transient adrenal insufficiency with circulatory collapse is a rare condition that occurs in preterm infants. Although the incidence of late-onset transient adrenal insufficiency in preterm infants has been reported in Japan, reports from Western countries are lacking. In addition, no study has investigated the effect of twin-to-twin transfusion syndrome (TTTS) in monozygot...

OBJECTIVES The goal of this study was to determine the prevalence and evolution of acquired right ventricular outflow tract obstruction (RVOTO) in the recipient twin in twin-twin transfusion syndrome (TTTS). BACKGROUND Twin-twin transfusion syndrome complicates 4% to 26% of diamniotic monochorionic twin gestations and is associated with high fetal morbidity and mortality. Cardiac dysfunction ...
متن کاملComparing Perinatal Outcome in Twin and Singleton Pregnancies Regarding Doppler Evaluation of Uterine Artery Indices in the Second Trimester
Background: Prediction of adverse perinatal and postnatal outcomes could be possible by using ultrasound Doppler evaluation, however there are some controversies regarding this issue in the literature. The goal of present study was to evaluate predictive value of Doppler indices in single and twin pregnancies during second trimester. Materials and Methods: This prospective study was conducted i...
