CT and MRI of coronary artery disease: evidence-based review

Giant right coronary artery aneurysm. Case Report

Introduction: Coronary aneurysms are rare and are linked to drug abuse; symptomatology depends on the coronary anatomy. This is a case of acute coronary syndrome associated with a giant right coronary aneurysm.Case description: A 40-year-old male, with history of heroin and crack use since age 20, attended consultation due to dyspnea, stable angina and diaphoresis. An electrocardiogram showed ST segment overlay on the underside and troponin problems. A coronary catheterization was performed, which revealed apparent inconclusive aortato-right atrium fistula. Based on the findings, angiotomography and magnetic resonance imaging were performed, finding a giant right coronary aneurysm. The aneurysm was resected using extracorporeal circuit, femoral cannulation, moderate hypothermia, aortic cross-clamping and cardioplegia, and the right coronary artery was revascularized with the left internal saphenous vein. The patient had a satisfactory postoperative period and was discharged after 7 days.Conclusion: There is an important association between drug use and the development of coronary aneurysms. Aneurysm size makes diagnosis difficult, so complementary studies are necessary to establish a differential diagnosis. An appropriate surgical approach allows for a complete resection of the aneurysm and optimal coronary revascularization.

A Rare Combination of Giant Right Coronary Artery Aneurysm

Context:

Giant coronary artery aneurysm (CAA) in adults is a rare clinical entity with an estimated incidence of 0.02%. CAA is commonly found in the right coronary artery with significant number of cases associated with fistula formation.

Case Report:

We describe a rare case of an 87 year-old man with large CAA with fistulous drainage into the right ventricle (RV) along with RV free wall vegetation as a cause of chronic weakness and lethargy.

Conclusion:

Giant CAA with fistulous drainage to the RV could present in the form of infective endocarditis. Early detection and surgical treatment would provide a significant benefit to these patients.
