Abstract：Objective To investigate the complications of twin-twin transfusion syndrome (TTTS) in preterm infants and to analyze the clinical conditions and prognosis of cardiac abnormalities in TTTS recipients. Methods A retrospective analysis was performed on the clinical data of 17 pairs of preterm infants with TTTS born between June 2009 and December 2012. Results Compared with the recipients, the donors had significantly lower body weights (1.4±0.6 kg vs 1.9±0.6 kg; PConclusions Among preterm infants with TTTS, the recipients are more susceptible to complications of valvular heart disease and cardiomyopathy. Fetal echocardiography, evaluation of cardiac function, and treatment should be performed for recipients as early as possible to improve the prognosis.
