- Without a heart.
When blood flows in reverse through an acardiac twin (one without a functioning heart) as it is pumped by the other, typically normal twin.
The term “reversed perfusion” is used to describe this scenario because blood enters the acardiac/acephalic twin through reversed flow through its umbilical artery and exits through the umbilical vein, which is opposite to the normal blood supply of the fetus.
In the TRAP sequence, the acardiac/acephalic twin receives all of its blood supply from the normal, or so-called pump twin.
Using color and power Doppler on ultrasound, complete occlusion of blood flow to the acardiac/acephalic twin was confirmed.
This is especially true when the acardiac/acephalic twin is greater than 50 percent of the size of the pump twin by calculated estimated weight.
When the acardiac/acephalic twin outweighs the pump twin by more than 50 percent, death occurs in 64 percent of cases.
Twin A was a typical acardiac/acephalic twin with massive diffuse soft tissue edema and an incompletely formed skeleton with no normal head structures, no normal stomach, kidneys or urinary bladder, and the absence of normal cardiac structures.
If the acardiac/acephalic twin outweighs the pump twin by more than 75 percent, death occurs in 95 percent of cases.
The reversed arterial flow in the acardiac/acephalic twin should be documented using color flow Doppler.
