Summary

This study details a newborn with complex congenital heart defects and right atrial isomerism, diagnosed via 2-D Doppler echocardiography. The rare, lethal condition led to surgical mortality, highlighting diagnostic challenges.

Area of Science:

  • Pediatric Cardiology
  • Medical Imaging
  • Congenital Heart Disease

Background:

  • Right atrial isomerism is a rare congenital condition.
  • Complex congenital heart malformations present significant diagnostic and therapeutic challenges in neonates.
  • Anomalous pulmonary venous connection requires precise imaging for diagnosis and surgical planning.

Observation:

  • A neonate presented with cyanosis, heart murmur, and respiratory distress.
  • Echocardiography revealed right atrial isomerism, severe left ventricular hypoplasia, pulmonary atresia, and ductus arteriosus.
  • Detailed imaging demonstrated an uncommon obstructive total anomalous pulmonary venous connection.

Findings:

  • Two-dimensional Doppler color echocardiography reliably diagnosed complex cardiac anomalies and anomalous pulmonary venous connection.

  • Cardiac catheterization confirmed the echocardiographic findings.
  • The infant underwent surgical repair but did not survive due to the severity of the malformations.

    • Implications:

    • The combination of right atrial isomerism, complex cardiac anomalies, and obstructive total anomalous pulmonary venous connection is often lethal in neonates.
    • Two-dimensional echo color flow Doppler is an indispensable tool for diagnosing and guiding management of these critical conditions.
    • Improved diagnostic accuracy through advanced imaging may aid in better surgical planning and outcomes for complex congenital heart disease.
