Extremely rare single right coronary artery: multidetector computed tomography findings

Area of Science:

• Cardiovascular Imaging
• Anatomical Variations
• Radiology

Background:

• Coronary artery anomalies occur in 1.3% of patients undergoing angiography.
• Most anomalies are clinically insignificant incidental findings.
• However, some can lead to severe symptoms like angina, syncope, arrhythmias, or sudden death.

Observation:

• This case report details coronary CT angiography findings.
• It focuses on an exceptionally rare coronary anomaly: the Lipton R-I type single right coronary artery.
• This specific anomaly has been documented in very few cases previously.

Findings:

• The Lipton R-I type single right coronary artery has a prevalence of only 0.0007% in the population.
• Coronary CT angiography is effective in visualizing such rare anatomical variations.
• The case highlights the importance of detailed imaging for identifying congenital coronary artery abnormalities.

Implications:

• Accurate diagnosis of rare coronary anomalies is crucial for risk stratification.
• Understanding these variations aids in preventing potential cardiac events.
• This case contributes to the literature on rare coronary artery anomalies and their imaging characteristics.
