Insights
A rare congenital anomaly, single coronary artery, was observed in a 70-year-old man. This case highlights the R-II-B subtype and its clinical significance in managing complex cardiac conditions.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Anatomical Variations
Background:
- Single coronary artery (SCA) is a rare congenital anomaly where one artery supplies the entire heart.
- Understanding SCA subtypes is crucial for diagnosis and management.
- Coronary artery anomalies can present with various clinical manifestations.
Observation:
- A 70-year-old male patient presented with mitral valvular insufficiency.
- Coronary angiography revealed a rare single coronary artery anomaly (R-II-B subtype).
- The anomalous artery originated from the right sinus of Valsalva and coursed between the aorta and pulmonary artery.
Findings:
- The patient had atherosclerotic disease in the right and left circumflex coronary arteries.
- The single coronary artery supplied the entire myocardium.
- The R-II-B subtype was identified, characterized by its origin and course.
Implications:
- This case underscores the importance of detailed coronary angiography in identifying rare coronary anomalies.
- Accurate classification of SCA subtypes is essential for surgical planning and risk stratification.
- Further research into the long-term clinical outcomes of different SCA subtypes is warranted.
Abstract:
A single coronary artery is a rare congenital anomaly of the coronary arteries where only one coronary artery arises from the aortic trunk by a single coronary ostium, supplying the entire heart. We report a case of a 70 years-old man with mitral valvular insufficiency and atherosclerotic right and left circumflex coronary arteries, in whom coronary angiography showed a single coronary artery arising from a single ostium in the right sinus of Valsalva (R-II-B subtype) and transverse trunk coursed between aorta and pulmonary artery. The clinical significance and subtype of the single coronary artery are discussed.
