0165: Outcome after drug-eluting stents for cardiac allograft vasculopathy
PurposeCardiac allograft vasculopathy (CAV) constitues a primary cause of death after heart transplantation. Bare metal stents (BMS) have been used for revascularization, but they are associated with a high-risk of restenosis.Abstract 0474 – Figure: Kaplan-Meier estimates of one-year mortalityLimited data have shown favourable results with percutaneous coronary interventions (PCI) using drug-eluting stents (DES) in this specific population. Our study focuses on intra-stent restenosis (ISR) for DES in CAV, on new revascularisation and mortality.Methods97 consecutive heart transplant recipients with successful PCI were treated with DES (n=106) and BMS (n=25). They were prospectively followed-up at one year after PCI. An angiographic lesion-based analysis at 12-month follow-up and a patient-based survival analysis were performed.ResultsThe lesion-based analysis within 12 months after PCI showed an ISR rate with BMS of 12% and an ISR rate with DES of 3.8%. The target lesion revascularization (TLR) was 8% for BMS and 2.8% for DES. However, the target vessel revascularization was higher (16.5%) and the remote lesion revascularization was 8.7%, indicating the rapid occurrence of new significant lesions. Cardiac mortality at one year was 9.7% and extra- cardiac mortality was 2.9%.ConclusionsDES are associated with a low rate of TLR and can safely be used in heart transplant recipients with coronary artery disease. However, new significant lesions occurred at one year indicating a progression of CAV
