Summary
Atheromatous aneurysms of the right coronary artery, even without significant stenosis, can cause myocardial infarction. Long-term anticoagulation and antiplatelet therapy may prevent future clinical events.
Area of Science:
- Cardiology
- Vascular Medicine
- Interventional Cardiology
Background:
- Coronary artery aneurysms (CAAs) are uncommon vascular abnormalities.
- While CAAs associated with significant coronary stenosis are well-documented, those without stenosis are less frequent.
- Understanding the pathophysiology and clinical outcomes of CAAs without stenosis is crucial.
Observation:
- Two cases of atheromatous aneurysms of the right coronary artery (RCA) are presented.
- These aneurysms were not associated with critical coronary artery stenosis.
- Myocardial infarctions occurred in these patients, treated successfully with intravenous thrombolysis.
Findings:
- Aneurysms without significant stenosis appear to be less common than those with stenosis.
- The prognosis for patients with CAAs not associated with significant stenosis may be similar to individuals without coronary artery disease.
- Local thrombosis within the aneurysm is identified as a key factor in clinical manifestation.
Implications:
- Early recognition and management of CAAs without stenosis are important.
- Long-term combined therapy with platelet antiaggregants and oral anticoagulants is recommended for prevention.
- Further research into the long-term outcomes of these specific lesions is warranted.
