Percutaneous coronary intervention for cardiac allograft vasculopathy in Asian patients

摘要


Background: The optimal treatment of cardiac allograft vasculopathy (CAV) remains controversial. Percutaneous coronary intervention (PCI) is one of the treatment options. There was paucity of data on Asian patients with CAV undergoing PCI. The purpose of our study was to investigate the clinical outcomes of PCI in Asian patients with CAV. Methods and Results: The study involved 21 heart transplant recipients who underwent PCI for 40 de novo coronary lesions since 2004. The treatment included 20 lesions with stenting and 20 lesions with balloon angioplasty.All PCIs were successful and there were no in-hospital complications. The follow-up angiography was performed after a mean period of 37±17 months. Comparing with the balloon angioplasty group, the stenting group showed significantly higher binary restenosis rate (80% vs. 3%, p=0.001), higher percentage diameter restenosis (71±29 vs. 46±21%, p=0.004), and higher late lumen loss (2.1±1 vs. 0.9±0.4mm, p<0.001). Kaplan-Meier survival curves showed that the target lesion revascularization rates were significantly higher in the stenting group than the balloon angioplasty group (70 vs. 25%, p=0.021). Conclusions: PCI can be performed safely in cardiac transplant recipients. The need for repeat intervention was common. Target lesion revascularization rates were significantly higher in the stenting group compared to the balloon angioplasty group. Further trials are required to evaluate the optimal PCI strategy in Asian patients with CAV.
