A puzzling CHD: a late diagnosis of left atrial isomerism

Area of Science:

• Cardiology
• Medical Imaging
• Congenital Heart Disease

Background:

• Complex cardiac anatomy presents diagnostic challenges.
• Previous cardiac surgeries can complicate anatomical assessment.
• Heterotaxy syndrome, particularly left isomerism, is a rare congenital condition.

Observation:

• A 41-year-old patient with a history of two cardiac surgeries presented with an unknown complex cardiac anatomy.
• Multimodality imaging was utilized for diagnostic evaluation.

Findings:

• Retrospective diagnosis identified heterotaxy syndrome (left isomerism).
• The patient's complex cardiac anatomy was elucidated through advanced imaging techniques.

Implications:

• Accurate diagnosis of rare congenital heart conditions is crucial for patient management.
• Multimodality imaging is vital for characterizing complex cardiac structures.
• Understanding left isomerism aids in surgical planning and prognosis for affected individuals.
