A rare case of acardius, a twin pregnancy complication, was observed in a tenthgravida woman. This condition, where one twin lacks a heart, did not cause obstetrical issues and is explained by vascular anastomoses in multiple pregnancies.

Area of Science:

  • Obstetrics and Gynecology
  • Perinatology
  • Fetal Medicine

Background:

  • Acardius, a rare congenital anomaly, occurs in twin pregnancies.
  • It is characterized by the absence of a heart in one of the twins.
  • Understanding its etiology is crucial for managing multiple gestations.

Observation:

  • A 47-year-old tenthgravida woman presented with a postnatally detected acardius.
  • The acardius twin did not lead to any significant obstetrical complications during the pregnancy.
  • This case provides a unique clinical observation of an uncomplicated acardius.

Findings:

  • The most plausible explanation involves vascular anastomoses between twins in a multiple pregnancy.
  • A twin with a hemodynamic advantage supplies deoxygenated blood to the other twin.

  • This unequal blood supply results in the development of the acardius twin.

    • Implications:

    • This case highlights the importance of monitoring twin pregnancies for potential complications.
    • The proposed theory of vascular shunting offers a clear mechanism for acardius development.
    • Further research into managing twin vascular anomalies can improve perinatal outcomes.
