This case report details a rare congenital heart defect involving multiple anomalies of the left atrium and associated structures. Surgical intervention was successful despite severe pulmonary hypertension.

Area of Science:

  • Cardiology
  • Congenital Heart Disease
  • Cardiac Surgery

Background:

  • Congenital heart defects (CHDs) encompass a range of structural abnormalities present at birth.
  • Complex CHDs often involve multiple cardiac anomalies requiring thorough diagnostic evaluation.
  • Understanding rare CHD associations is crucial for effective clinical management.

Observation:

  • A rare case presented with a combination of cardiac anomalies: divided left atrium, supramitral stenosing ring, left superior caval vein connection to the left atrium roof, unroofed coronary sinus with interatrial communication, and ventricular septal defect.
  • Pulmonary venous obstruction was a significant concern in this complex presentation.
  • The patient exhibited severe preoperative pulmonary hypertension.

Findings:

Related Experiment Videos

  • Complete echocardiographic examination is vital for diagnosing complex congenital heart disease, particularly when pulmonary venous obstruction is suspected.
  • Surgical correction of the multiple cardiac anomalies was performed.
  • The surgical outcome was successful, even with significant preoperative pulmonary hypertension.

    • Implications:

    • This case highlights the importance of comprehensive echocardiography in identifying intricate congenital heart anomalies.
    • Successful surgical management of complex CHDs, even with severe comorbidities like pulmonary hypertension, is achievable.
    • Further research into rare CHD associations can improve diagnostic and therapeutic strategies.
