Background. Direct stent implantation without predilatation is considered a promising new technique that may reduce procedural time, radiation exposure, ischemic time and cost, but little information is available concerning the long-term outcome. The aim of this study was to investigate the long-term clinical outcome of successful direct stenting without predilatation. Methods. We prospectively undertook a clinical follow-up program (minimum 8 months) in a consecutive series of 101 patients (113 lesions) Results. Clinical follow-up was obtained in all 101 patients at a mean period of 12.8 months (range 8 to 18.9). Stress test results were available in 94 patients (94%). During the follow-up period, 23 patients (23%) had one or more events, which included death in 2 patients (2%), target vessel revascularization in 14 (14%), myocardial infarction in 1 (1%) and positive stress test results or recurrence of symptoms (Canadian Cardiovascular Society I to II) treated medically in 6 (6%). Cumulative event-free survival at 8 and 18 months were 80% and 72%, respectively. Long-term clinical event rate was not significantly different among the clinical presentations, lesion types, or stent types. Angiographic follow-up was performed in 43 (43%) patients with 45 lesions. Restenosis (defined as 50% diameter stenosis) was observed in 14 of the lesions (31%). Conclusions. Direct stenting without predilatation is an effective method of coronary intervention in terms of low long-term clinical event rate.
