Intrauterine Myocardial Infarction in a Twin Gestation Complicated by Twin-to-Twin Transfusion Syndrome

Abstract

Twin-to-twin transfusion syndrome (TTTS) is a known complication of 10% to 15% of monochorionic/diamniotic twin gestations. It is also known that the “recipient” twin in these pregnancies is at higher risk for cardiac abnormalities. Early identification of TTTS and recognition of changes in fetal cardiac function can reduce fetal morbidity and mortality. This case describes intrauterine myocardial infarction developing in the recipient twin of a monochorionic/diamniotic twin gestation complicated by TTTS.
