Insights
A patient developed restenosis and aneurysm after percutaneous coronary intervention for a blocked left anterior descending artery. Coronary artery bypass grafting using the internal thoracic artery was successfully performed.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Surgery
Background:
- Acute anterior myocardial infarction requires prompt revascularization.
- Percutaneous transluminal coronary angioplasty (PTCA) is a common treatment for stenotic coronary arteries.
- Left anterior descending artery (LAD) stenosis significantly increases cardiovascular risk.
Observation:
- A 56-year-old man presented with acute anterior myocardial infarction.
- Successful LAD PTCA was performed.
- Three months post-PTCA, follow-up angiography revealed in-stent restenosis and aneurysm formation at the LAD lesion site.
Findings:
- The restenotic and aneurysmal LAD lesion posed a high risk for repeat PTCA.
- Coronary artery bypass grafting (CABG) was successfully performed using the internal thoracic artery (ITA).
Implications:
- This case highlights a rare complication of PTCA, including in-stent restenosis and aneurysm.
- CABG with ITA is a viable and safe alternative for managing complex post-PTCA LAD lesions.
- Careful long-term surveillance is crucial for patients undergoing coronary interventions.
Abstract:
A 56-year-old man was admitted to our medical center because of acute anterior myocardial infarction. Emergent percutaneous transluminal coronary angioplasty (PTCA) resulted in successful dilatation at the stenotic lesion of the left anterior descending artery (LAD). Three months later, coronary angiography showed not only a restenosis but also an aneurysm formation at the same portion. This lesion was too risky to redo PTCA. We successfully performed coronary bypass grafting with the internal thoracic artery.
