Anomalous single coronary artery on low dose MDCT

Area of Science:

• Cardiology
• Radiology
• Medical Imaging

Background:

• Coronary artery anomalies are uncommon congenital conditions affecting coronary artery origin, course, or structure.
• Prevalence in the general population is less than 1%, with presentations ranging from asymptomatic to sudden cardiac death.

Observation:

• Multi-detector computed tomography (CT) has significantly advanced the diagnosis of coronary artery anomalies.
• Its non-invasive nature and 3D reconstruction capabilities offer substantial benefits over traditional methods.

Findings:

• The study reports two cases of clinically significant single coronary artery anomalies: a single right coronary artery and a single left coronary artery.
• These cases highlight anomalies in both the origin and course of the coronary arteries.

Implications:

• Accurate definition of coronary anatomy using low-dose CT is crucial for clinical decision-making and timely intervention.
• Low-dose CT serves as an excellent diagnostic and follow-up tool, reducing the need for repeated invasive procedures.
