Broncho-atrial discordance. A clinically diagnosed case.

Area of Science:

• Cardiology
• Congenital Heart Disease
• Medical Imaging

Background:

• Determining atrial situs is crucial for analyzing complex congenital heart disease.
• Bronchial pattern on chest X-ray typically predicts atrial arrangement but exceptions exist.

Purpose of the Study:

• To report a rare case of discordance between atrial arrangement and bronchial morphology.
• To emphasize the importance of considering exceptions in clinical diagnosis.

Main Methods:

• Chest X-ray for bronchial pattern analysis.
• Diagnostic evaluation for atrial situs determination in a patient with congenital heart disease.

Main Results:

• The patient presented with usual bronchial morphology.
• However, the atrial arrangement was diagnosed as mirror-image, a discordance between the two findings.
• This discordance was identified during the patient's lifetime.

Conclusions:

• Exceptions to the rule correlating bronchial pattern with atrial situs can occur.
• Clinical diagnosis requires careful consideration of potential discordance, even when typical imaging patterns are observed.
• This case underscores the need for comprehensive assessment in congenital heart disease.
