Insights
A rare case of a giant coronary artery aneurysm presenting as acute myocardial infarction was successfully treated with angioplasty and stenting. This highlights challenges in managing rare coronary artery conditions.
Area of Science:
- Cardiology
- Vascular Medicine
- Interventional Cardiology
Background:
- Giant coronary artery aneurysms are rare vascular malformations.
- Diagnosis within acute coronary syndrome (ACS) presentation is exceptionally uncommon.
- Limited established guidelines exist for managing these complex cases.
Purpose of the Study:
- To report a unique case of a giant coronary artery aneurysm.
- To discuss the diagnostic and therapeutic challenges encountered.
- To contribute to the limited literature on managing this rare condition.
Main Methods:
- Case presentation of a 75-year-old male with myocardial infarction.
- Diagnostic imaging including echocardiogram and coronary angiography.
- Interventional treatment involving angioplasty and drug-eluting stent implantation.
Main Results:
- A giant aneurysm of the circumflex artery with distal occlusion was identified.
- The patient presented with infero-postero-lateral myocardial infarction.
- Successful revascularization of the occluded coronary artery was achieved.
Conclusions:
- Giant coronary artery aneurysms can present as acute coronary syndromes.
- Multidisciplinary Heart Team evaluation is crucial for management decisions.
- Percutaneous coronary intervention can be a viable treatment option despite management uncertainties.
Abstract:
We describe the case of a 75-year-old hypertensive patient who comes to the emergency room for an infero-postero-lateral myocardial infarction. The entry echocardiogram showed a rounded formation with mixed echogenicity (maximum transverse diameter 4.5 cm), attached to the free wall of the left atrium and without any hemodynamic impact. Coronary angiography revealed a giant aneurysm of the circumflex artery, followed by an occlusion of the distal tract. After Heart Team evaluation, angioplasty with implantation of a drug-eluting stent was performed in the occluded coronary tract. This is one of the very rare cases in the literature of a giant coronary aneurysm diagnosed within the clinical picture of acute coronary syndrome. There is a lack of guidelines and consensus documents regarding management of this condition. In our case report, we discuss the resulting therapeutic challenges.
