Abstract
- Many interventional cardiologists rely upon percutaneous coronary intervention (PCI) with drug-eluting stents (DES), but DES may provoke serious complications, such as stent thrombosis and delayed restenosis. Previous studies of bare metal stent placement showed regression of neointimal proliferation after 6 months. Here, we report the case of a 50-year-old man demonstrating spontaneous regression of neointimal hyperplasia after undergoing PCI with a bare metal stent to treat a middle left anterior descending (LAD) artery lesion. Coronary angiography showed 90% diffuse restenosis at 6 months after stent placement, but the patient refused PCI due to monetary concerns. After 29 months, follow-up angiography revealed spontaneous regression of restenosis in the middle LAD.
