Summary

Cor triatriatum dexter (CTD) is a rare heart defect where the right atrium is divided. Advanced echocardiography is crucial for diagnosing this complex congenital anomaly.

Area of Science:

  • Cardiology
  • Pediatric Cardiology
  • Congenital Heart Disease

Background:

  • Cor triatriatum dexter (CTD) is a rare congenital heart defect characterized by the right atrium's subdivision due to a persistent sinus venosus valve.
  • This anomaly can lead to cyanosis and presents diagnostic challenges.

Observation:

  • Two pediatric patients with CTD, diagnosed and treated in 1979 and 1992, are presented.
  • Initial misdiagnosis of one patient as cor triatriatum sinister highlights the complexity.

Findings:

  • Two-dimensional and Doppler echocardiography, alongside cardiac catheterization and surgery, were used to delineate the anatomical and physiological aspects of CTD.
  • High-resolution imaging confirmed the presence of an atrial membrane and its effects.

Implications:

  • This case series underscores the diagnostic utility of advanced echocardiographic techniques in evaluating complex congenital heart defects like CTD.
  • Accurate diagnosis through imaging is vital for appropriate surgical planning and patient management.
