Asymptomatic young man with an incidental murmur.

Area of Science:

• Cardiology
• Medical Imaging
• Congenital Heart Disease

Background:

• Adult presentation of congenital heart disease is uncommon.
• Incidental findings during routine examinations can reveal significant pathology.
• Early diagnosis of coronary anomalies is crucial for preventing complications.

Observation:

• A 32-year-old asymptomatic male presented with an incidental cardiac murmur.
• Transthoracic echocardiography (TTE) and cardiac CT angiography (CTA) were performed.
• Imaging revealed an anomalous left coronary artery originating from the pulmonary artery (ALCAPA).

Findings:

• The patient had an anomalous left coronary artery from the pulmonary artery (ALCAPA).
• This congenital anomaly was diagnosed using TTE and CTA.
• The patient was asymptomatic despite the significant cardiac anomaly.

Implications:

• Highlights the importance of investigating incidental cardiac murmurs, even in asymptomatic adults.
• Demonstrates the utility of advanced imaging modalities like CTA in diagnosing complex congenital heart disease.
• Underscores the potential for adult diagnosis of previously undetected congenital heart anomalies.
