Single coronary artery with "high take-off" origin in a patient with rheumatic mitral stenosis--a case report
Insights
This case report details a rare single coronary artery (R-1 subtype) with a high-take-off origin, originating from the ascending aorta. This unique anatomical variation, coursing between the aorta and pulmonary artery, is presented for the first time in medical literature.
Area of Science:
- Cardiology
- Anatomical Variations
- Congenital Heart Disease
Background:
- Rheumatic mitral stenosis is a significant valvular heart condition.
- Anomalous coronary artery origins can have critical clinical implications.
- Single coronary arteries are rare congenital anomalies.
Observation:
- A patient presented with rheumatic mitral stenosis and an unusual coronary artery anatomy.
- The coronary artery was a single R-1 subtype, originating from the ascending aorta with a "high take-off" position.
- This anomalous vessel coursed between the aorta and pulmonary artery.
Findings:
- This represents the first reported case of an R-1 subtype single coronary artery with a "high take-off" origin.
- The anatomical course of the anomalous artery between the aorta and pulmonary artery is a key feature.
- The clinical significance and differential diagnosis of this rare anomaly were discussed.
Implications:
- Understanding this rare coronary artery anomaly is crucial for accurate diagnosis and surgical planning.
- This case highlights the importance of detailed coronary artery imaging in patients with congenital heart defects.
- Further research into the clinical outcomes associated with this specific anomaly is warranted.
Abstract:
In this case report, a patient with rheumatic mitral stenosis and R-1 subtype single coronary artery arising from the ascending aorta ("high take-off" origin) and coursing between the aorta and pulmonary artery is presented. The clinical significance and differential diagnosis are discussed. To the authors' knowledge, this is the first case reported in the literature with a single R-1 subtype coronary artery that shows "high take-off" origin.
