Insights
This case report details a rare congenital coronary anomaly where the right coronary artery was absent. Percutaneous coronary intervention successfully treated associated stenosis, highlighting tailored approaches for complex coronary artery disease.
Area of Science:
- Cardiology
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Coronary artery anomalies pose significant challenges in interventional cardiology.
- Management requires tailored strategies due to unique anatomical variations.
- Congenital coronary anomalies are infrequently documented, necessitating case reports for knowledge advancement.
Observation:
- A 70-year-old male presented with refractory angina and a rare congenital coronary anomaly: absence of the right coronary artery ostium.
- Myocardial perfusion relied solely on the left coronary system.
- Cardiac catheterization identified stenosis in the mid-left anterior descending artery.
Findings:
- Percutaneous coronary intervention was successfully performed despite anatomical complexities.
- The procedure addressed the critical stenosis in the left anterior descending artery.
- This case highlights successful intervention in a patient with a rare coronary anomaly.
Implications:
- Meticulous diagnostic evaluation and advanced imaging are crucial for managing rare coronary anomalies.
- A multidisciplinary approach is essential for optimizing patient care and outcomes.
- Further research into diagnostic and therapeutic considerations for rare coronary anomalies is warranted to improve treatment strategies.
Abstract:
Coronary artery anomalies present unique interventional challenges, particularly when associated with significant coronary artery disease. This case report contributes to the limited literature on congenital coronary artery anomalies, emphasizing the need for tailored approaches to optimize patient care. We present a case of a 70-year-old male with refractory angina and a rare congenital coronary anomaly characterized by the absence of the right coronary artery ostium, necessitating reliance on the left coronary system for myocardial perfusion. Cardiac catheterization revealed mid-left anterior descending artery stenosis, prompting percutaneous coronary intervention. Despite the anatomical complexities encountered, the procedure was successfully performed. This case underscores the importance of meticulous diagnostic evaluation, advanced imaging techniques, and a multidisciplinary approach to managing patients with rare coronary anomalies. This report also emphasizes the unique diagnostic and therapeutic considerations by providing a comprehensive literature review and identifying areas for further research to advance treatment strategies and improve outcomes.
