An entire coronary system arising from right coronary cusp: a rare anomaly

Area of Science:

• Cardiology
• Medical Imaging
• Anatomical Variations

Background:

• Coronary artery anomalies (CAAs) affect about 0.6% of individuals undergoing angiography.
• While often benign, some CAAs can precipitate serious cardiac events like myocardial infarction and sudden cardiac death.
• Anomalous origin of the entire coronary circulation from a single cusp is exceptionally rare.

Observation:

• A 57-year-old male presented with exertional chest pain and dyspnea.
• Invasive coronary angiography revealed a unique anomaly: all three major coronary arteries arising from the right coronary cusp.
• This anatomical variation represents a significant deviation from typical coronary artery anatomy.

Findings:

• The study details an extremely uncommon congenital coronary anomaly.
• The entire coronary arterial tree originated from the right coronary cusp in the presented case.
• This anatomical configuration has critical implications for cardiovascular diagnosis and treatment planning.

Implications:

• Accurate definition of coronary anatomy is paramount in patients with suspected or confirmed ischemic heart disease.
• Understanding rare CAAs is essential for guiding appropriate cardiac interventions and surgical strategies.
• This case underscores the need for comprehensive angiographic assessment to identify and manage potentially life-threatening coronary anomalies.
