Woven Right Coronary Artery Associated with Myocardial Infarction

Introduction

Congenital coronary artery anomalies are rare, but when they occur, they can significantly impact cardiovascular health. One such anomaly, Woven Coronary Artery (WCA), is characterized by the division of an epicardial coronary artery into multiple thin channels, which later reanastomose. While traditionally considered benign, emerging cases suggest possible links to myocardial infarction.

Understanding Woven Right Coronary Artery and Its Clinical Presentation

A recent case study detailed the diagnosis and treatment of a 46-year-old male who presented with stable angina pectoris. His electrocardiogram (ECG) showed Q waves in the inferior leads, while echocardiography revealed left ventricular akinesis with a 50% ejection fraction. A coronary angiogram indicated 70% stenosis in the left anterior descending artery (LAD), 99% stenosis in the circumflex artery, and a woven right coronary artery with a twisting course. Given the severity of the condition, the patient underwent bypass surgery.

Clinical Implications and Differential Diagnosis

Diagnosing WCA is challenging because it mimics intracoronary thrombus and dissection, leading to potential misinterpretations. The American College of Cardiology (ACC) emphasizes the importance of precise imaging techniques to avoid unnecessary interventions. Although WCA has been historically considered benign, its potential association with myocardial infarction warrants further research.

Key Findings of the Study

• Congenital Anomaly: WCA is an extremely rare malformation.
• Potential Misdiagnosis: Can be mistaken for coronary thrombosis or dissection.
• Risk Factors: The study suggests that WCA may contribute to ischemic heart disease in some cases.
• Need for Further Research: More data is needed to understand the long-term cardiovascular impact of WCA.

Conclusion and Call to Action

Although Woven Coronary Artery (WCA) has been considered a benign anomaly, recent findings highlight its potential link to myocardial infarction. Proper diagnosis through advanced imaging and clinical evaluation is crucial for effective treatment planning.
