Insights
A novel micro-mesh stent effectively treated a large coronary artery aneurysm with significant thrombus in a myocardial infarction patient. This approach shows promise for complex coronary artery disease cases.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Background:
- Optimal treatment for aneurysmal or ectatic coronary arteries during acute myocardial infarction remains debated.
- Revascularization via percutaneous intervention or surgery has shown limited success and poor outcomes in these cases.
Background:
The optimal treatment of aneurysmal or ectatic culprit vessels in the setting of acute myocardial infarction is still matter of debate, as revascularization with either percutaneous intervention or surgery is associated with low procedural success and poor outcomes.
Case Summary:
We report the case of a 55-year-old male patient, admitted for inferior ST-elevation myocardial infarction, who underwent successful percutaneous implantation of a micro-mesh self-expanding nitinol carotid stent in a right coronary aneurysm with intravascular ultrasonography measured diameter of 9 mm and massive thrombus apposition.
Discussion:
The technical characteristics of the micro-mesh self-expanding nitinol carotid stent allow for adequate plaque coverage and good apposition even in large vessels, making this device particularly suitable for the treatment of coronary lesions with high thrombus burden, when severe coronary ectasia or aneurysms are present.
