Answer:
TRAP is known as an absence of the fetal heart organ in intrauterine life, but not in any situation.
But in that during the pregnancy of twins, that is why one of the embryos presents perfect cardiac pumping with the cardiac vital organ present, and another does not.
This affects the embryo or fetus that has the heart through which it has to send the blood supply through the venous artery to the twin that is developing together with it, at risk of life.
In simple words TRAP is the absence of the heart in one of the twins in intrauterine life.
Explanation:
In these cases, the twin who sends blood circulation through the venous artery to the neighboring twin without a heart pump is called a twin pump and in almost 50% of cases he dies of cardiac overload.
