Acardiac fetus: a challenge to pathologists, obstetricians and neonatologists
Autopsy and Case Reports, 2011 Acardius is one of the most severe human malformations, a rare complication present only in monozygotic and monochorionic multiple pregnancies. In this disorder, the major defect is the lack of well-defined cardiac structure in acardiac fetus, whose ...

Hypothesized pathogenesis of acardius acephalus, acormus, amorphus, anceps, acardiac edema, single umbilical artery, and pump twin risk prediction [PDF]
Birth Defects Research, Volume 114, Issue 5-6, Page 149-164, March 2022., 2022 Abstract Background Acardiac twinning complicates monochorionic twin pregnancies in ≈2.6%, in which arterioarterial (AA) and venovenous placental anastomoses cause a reverse circulation between prepump and preacardiac embryos and cessation of cardiac function in the preacardiac.

Management of twin reversed arterial perfusion sequence: one center's experience [PDF]
Annals of Saudi Medicine, 2023 BACKGROUND: Twin reversed arterial perfusion (TRAP) sequence is a rare condition that affects primarily monozygotic monochorionic twin pregnancies in which a normal twin acts as a pump (donor) for an acardiac recipient (perfuse) twin.

Case Report: Missed diagnosis of twin reversed arterial perfusion sequence discovered at delivery: lessons from poorly monitored monochorionic twin pregnancy [PDF]
Frontiers in MedicineTwin reversed arterial perfusion (TRAP) sequence is an extremely rare and serious complication that occurs specifically in multiple monozygotic pregnancies. Early sonography and Doppler examination are the cornerstones for an accurate diagnosis.

Thoraco-Omphalopagus Conjoined Twins Following IVF With Day 5 Embryo Transfer: A Rare Case Report and Multidisciplinary Management Approach. [PDF]
Clin Case RepABSTRACT Conjoined twinning is a rare and severe complication of monozygotic pregnancies. Assisted reproductive technologies (ART), including in vitro fertilization (IVF), may increase the risk of such anomalies. We report a case of thoraco‐omphalopagus conjoined twins following a day 5 embryo transfer after IVF with intracytoplasmic sperm injection ...

“The Strange Case of Dr Pump and Mr Acardiac”: The Twin Reversed Arterial Perfusion (TRAP) Sequence in Two Monochorionic Monoamniotic (MCMA) Twin Pregnancies—Diagnosis, Prognosis and Management: Review of Literature [PDF]
Diagnostics, 2023 The Twin Reversed Arterial Perfusion (TRAP) Sequence is an extremely rare complication of monochorionic twin pregnancies, with one severely malformed twin (the “acardiac”) lacking autonomous placental blood supply and being perfused by the co-twin (the ...

Acardiac Twinning (Twin Reversed Arterial Perfusion Sequence): A Review of Prenatal Management [PDF]
Taiwanese Journal of Obstetrics & Gynecology, 2005 Acardiac twinning, or the twin reversed arterial perfusion (TRAP) sequence, occurs in 1% of monozygotic twins, or 1 in 35,000 births. It is caused by the development of arterioarterial vascular anastomoses between the umbilical arteries of monozygotic ...
