Acardiac twins: a case series.
J Coll Physicians Surg Pak Jan ;17(11):691-3.

Acardiac twinning is a severe and rare complication of monochorionic placentation. The acardiac twin does not survive while mortality of the normal twin is about 50-70% as the normal twin has to provide circulation not only for itself but also for acardiac twin. Proper timing of the delivery is of prime importance to the survival of the normal fetus for which emphasis is placed on close sonographic monitoring for early antenatal diagnosis. This series describes three such cases, which are now termed Twin Reversed Arterial Perfusion (TRAP) sequence.
