Summary
Twin reversed arterial perfusion sequence (TRAP) is a rare anomaly unique to monochorionic (MC) multiple pregnancies. It is estimated to affect 2.5% of MC pregnancies or 1 in 10 000 pregnancies [1]. TRAP more commonly occurs in monoamniotic than in diamniotic pregnancies, but because diamniotic twins are more common, most TRAP cases are seen in a diamniotic setting. TRAP consists of the combination of a normal-looking twin who pumps blood towards a severely abnormal co-twin. This normal twin is therefore called the ‘pump twin.’ The severely abnormal twin usually does not have a functional heart, hence also the name acardiac twin.
