If left untreated, the pump<unk>  will die in 50–75% of cases. After diagnosis, ultrasound and amniocentesis are used to rule out genetic abnormalities in the pump<unk> . A procedure may then be performed which will stop the abnormal blood flow. The acardiac<unk>  may be selectively removed. The umbilical cord of the acardiac<unk>  may be surgically cut, separating it from the pump<unk> , a procedure called fetoscopic cord occlusion. Or a radio-frequency ablation needle may be used to coagulate the blood in the acardiac<unk> 's umbilical cord. This last procedure is the least invasive. These procedures greatly increase the survival chances of the pump<unk> , to about 80%. The pump<unk>  will be monitored for signs of heart failure with echocardiograms. If the pump<unk> 's condition deteriorates, the obstetrician may recommend early delivery. Otherwise, the pregnancy continues normally. Vaginal birth is possible unless the fetus is in distress, although it is recommended that the delivery take place at a hospital with NICU capabilities.
