Zusammenfassung
Anamnese und klinischer Befund: Ein 52-jähriger Patient mit instabiler Angina pectoris wurde von einer auswärtigen Klinik zur Koronarangiographie überwiesen. Eine koronare 1-Gefäß-Erkrankung war bekannt. 11 Jahre zuvor war eine Ballondilation des Ramus interventricularis anterior (RIVA) durchgeführt worden. Zwei Monate später wurden zwei Bare-metal-Stents (BMS) aufgrund einer frühen Rezidivstenose implantiert.
Untersuchungen: Eine wegen Angina pectoris abgebrochene Belastungsergometrie zeigte horizontale ST-Streckensenkungen in V4 – V6.
Therapie und Verlauf: Es erfolgte eine Koronarangiographie, in der sich eine In-Stent-Stenose des proximalen RIVA bei koronarer 1-Gefäßerkrankung zeigte. Es erfolgte eine erfolgreiche perkutane koronare Intervention des RIVA mit Implantation eines Medikamenten-freisetzenden-Stents (DES). Der Patient war postinterventionell beschwerdefrei.
Folgerung: Eine In-Stent-Stenose eines Bare-metal-Stents kann sich in seltenen Fällen auch nach über 11 Jahren entwickeln, ohne dass es zu einer Progression der koronaren Herzkrankheit an anderen Stellen des Koronarsystems kommt.
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.
