[In-stent-stenosis of a bare-metal stent 11 years after its implantation].

HISTORY AND ADMISSION FINDINGS: A 52-year-old man was admitted to our hospital with unstable angina pectoris. A balloon angioplasty of his left anterior descending artery had been performed 12 years ago and two bare-metal stents had been implanted two months later for an early restenosis.

DIAGNOSTIC PROCEDURES: Bicycle ergometry was stopped because the patient experienced angina pectoris and the electrocardiogram showed ST-segment depression in leads V4-V6.

TREATMENT AND OUTCOME: A coronary angiography was performed and a single-vessel disease with a significant in-stent stenosis of the proximal left anterior descending artery was diagnosed. Another successful percutaneous coronary intervention was performed with implantation of a drug-eluting stent. The further hospital course was uneventful.

CONCLUSION

Even after more than 11 years an in-stent stenosis of a bare-metal stent can occur without progression of coronary artery disease in the other coronary arteries.
