Two aortic valves in the parasternal long-axis view: Aortic dissection or artifact?

Area of Science:

• Cardiovascular Imaging
• Diagnostic Echocardiography
• Medical Imaging Artifacts

Background:

• Echocardiography is a primary tool for cardiac assessment.
• Accurate interpretation of echocardiographic images is crucial for patient diagnosis and management.
• Understanding potential imaging artifacts is essential for avoiding misdiagnosis.

Observation:

• A parasternal long axis view echocardiogram presented an artifactual appearance of two distinct aortic valves.
• This artifact mimicked a potential pathology requiring further investigation.

Findings:

• The observed dual aortic valve appearance was determined to be a refraction artifact.
• Computed tomography (CT) angiography definitively ruled out aortic dissection, a critical differential diagnosis.

Implications:

• This case highlights the importance of recognizing refraction artifacts in echocardiography.
• Proper identification of artifacts prevents unnecessary invasive procedures and ensures correct diagnosis.
• CT angiography serves as a vital tool for confirming or refuting suspected aortic pathologies suggested by echocardiography.
