From Small Coronary Artery Aneurysm to Giant Left Ventricle Aneurysm.

OBJECTIVE: To underscore how challenging the treatment of a coronary artery aneurysm (CAA) can be and highlight the need for consensus guidelines based on focused registries.

CLINICAL PRESENTATION AND INTERVENTION: A 58-year-old man presented with acute coronary syndrome and underwent elective stent placement on a right CAA. The procedure was complicated by inferior acute myocardial infarction; 8 months later, due to remodeling toward a left ventricular aneurysm of the inferior wall, he experienced several episodes of sustained ventricular tachycardia that required urgent surgical treatment.

CONCLUSION: The best therapeutic option for CAA is still a matter of controversy, and though the percutaneous approach can meet the technical challenges, 'heart team'-based decision-making is recommended. The case reported here showed that percutaneous treatment of CAA can be a challenging procedure, even in experienced and high-volume centers. In our patient's case, undersizing the covered stent led to further migration and to a complication that was more severe than the original disease.
