Diagnosis of this syndrome was made with ultrasonography that is usually helpful from 11 weeks of gestation. 5 At present there is a controversy regarding elective verses therapeutic treatment of reversed arterial perfusion sequence. 6 Here we are presenting [medcraveonline.com]

In a single individual this is incompatible with survival beyond the early stages of development, but cases have been reported in which joined twins share a heart present in only one. [medical-dictionary.thefreedictionary.com]

No two acardiac twins are formed exactly alike, so they may present differently. During ultrasound, an acardiac twin may appear as tissue mass or it may appear to be a twin who has died in the womb. [encyclopedia.com]

The normal twin is not always saved by prenatal treatment. Specialists have used laser and electrical cauterization, electrodes, serial amniocentesis, medications, and other treatments successfully. [encyclopedia.com]

Intra-fetal ablation is the treatment of choice because it is simpler, safer and more effective than cord occlusion techniques. [medcraveonline.com]

Treatment and prognosis The acardiac twin is non-viable and management is aimed at maintaining the viability of the other (donor/pump) twin, including close surveillance for development of hydrops. [radiopaedia.org]

Prognosis The acardiac or parasitic twin never survives as it is severely malformed and does not have a functioning heart. Complications associated with having an acardiac twin cause 50-70% of normal twins to die. [encyclopedia.com]

Invasive intervention is needed when the acardiac twin is more than 70% of the pump twin weighs; however, the prognosis appears to be poor. [medcraveonline.com]

Studies on its epidemiology and etiology are challenging and still rare. [rug.nl]

Two theories exist as to the etiology of this condition: One theory holds that the TRAP anomaly is caused by an abnormal twining event. 11 Deep placental anastomoses in early embryogenesis cause malformation of the acardiac twin. [medcraveonline.com]
