We describe the high‐pressure deployment of 2.5‐mm stents in small (< 2.5 mm) coronary vessels. Forty‐three lesions in 40 patients were treated. The mean reference vessel diameter was 2.3 ± 0.2 mm. The mean % luminal stenosis was 90 ± 9. The mean lesion length was 11.7 ± 9.1 mm. Sixteen lesions were pretreated with rotational atherectomy, and the remainder with PTCA. The rate of successful stent deployment was 41/43 (95%). The mean postintervention % stenosis was ‐1 ± 10. There were no in‐hospital deaths or procedure‐related Q‐wave MI. The patients were followed for a mean of 18 months. Eight patients (or 21%) developed recurrent chest pain and/or angiographically proven restenosis. One patient (3%) developed intermediate restenosis. Twenty‐nine patients (or 76%) either remain symptom‐free or have patent target sites on repeat angiography. It appears that reasonable acute and long‐term results can be achieved with 2.5‐mm stents in small coronary arteries using high‐pressure deployment techniques. Cathet. Cardiovasc.
