An asymptomatic case with single atrium.

Area of Science:

• Cardiology
• Congenital Heart Disease
• Echocardiography

Background:

• Single atrium (or common atrium) is a rare congenital heart defect characterized by the absence of septa between the atria.
• While often diagnosed in infancy, isolated cases can present in adulthood.

Observation:

• This report details an adult patient diagnosed with a single atrium.
• The diagnosis was made using transthoracic echocardiography.

Findings:

• Transthoracic echocardiography successfully identified the presence of a single atrium in an adult patient.
• This imaging modality is effective for detecting this rare cardiac anomaly.

Implications:

• Highlights the utility of echocardiography in diagnosing rare adult congenital heart disease.
• Emphasizes the need for considering uncommon cardiac defects in adult patients presenting with relevant symptoms or during routine screening.
