INTRODUCTION: Percutaneous treatment (PCI) of single lesions in the LAD with balloon angioplasty or bare-metal stent (BMS) often have poorer outcomes when compared to PCI of lesions in the other major coronary arteries. OBJECTIVE: To compare the long term safety and efficacy of DES vs. BMS for the treatment of single lesions in the LAD. METHODS: Between June 2002 and June 2003, 166 patients with single lesions in the LAD were treated with DES and compared to a historic cohort of 141 patients treated with BMS under the same inclusion/exclusion criteria. Long term clinical follow-up (approximately 2 years) was obtained in all patients. The primary endpoint was the comparison of major adverse cardiac events (MACE) defined as cardiac death, non fatal MI and target-lesion revascularization (TLR) between the two groups. RESULTS: Baseline clinical characteristics did not differ between groups. Procedure success was achieved in all cases with no in hospital MACE. After two years of follow-up, 95.7% of patients treated with DES and 73.7% treated with BMS were free from any MACE (p < 0.0001). TLR occurred in 15.6% and 1.2% of the patients receiving BMS and DES respectively (p < 0.0001). Although not significantly reduced, cardiac death was less frequent among patients treated with these DES (6.38% vs. 1.81%, p = 0.07). CONCLUSION: The use of DES for the treatment of single LAD lesions was superior to BMS due to a marked reduction in MACE rates, mainly at the expense of a very low need for RLA.
