Diagnosis of cor triatriatum by echocardiography

|April 1, 1977
Insights
Cor triatriatum diagnosis is aided by echocardiography, revealing a membrane in the left atrium. This imaging technique is crucial for identifying pulmonary venous obstruction in pediatric cardiac cases.
Area of Science:
- Cardiology
- Pediatric Cardiology
- Medical Imaging
Background:
- Cor triatriatum is a rare congenital heart anomaly characterized by an intra-atrial septum dividing the left atrium into two chambers.
- Accurate diagnosis is essential for timely surgical intervention and improved patient outcomes.
- Conventional diagnostic methods can sometimes be challenging in pediatric cases.
Observation:
- Echocardiography demonstrated a normal anterior mitral valve echo.
- A distinct, dense band of echoes was observed posterior to the aortic root.
- This echo-dense band was located within the body of the left atrium, consistent with a dividing membrane.
Findings:
- The echocardiographic findings suggested the presence of cor triatriatum.
- Cardiac catheterization confirmed the diagnosis.
- Surgical findings validated the echocardiographic and catheterization results.
Implications:
- Echocardiography serves as a vital non-invasive tool for diagnosing cor triatriatum in children.
- The study highlights the utility of echocardiography in assessing pulmonary venous obstruction.
- Early and accurate diagnosis through echocardiography can significantly impact management strategies for pediatric congenital heart disease.
Abstract:
The echocardiographic findings in a case of cor triatriatum are described. The diagnosis was suggested by a normal anterior mitral valve echo and a dense band of echoes posterior to the aortic root and within the body of the left atrium; it was documented at cardiac catheterization and proved surgically. Echocardiography is an important diagnostic aid in assessing pulmonary venous obstruction in children.
