Stenting of small coronary arteries was long contra-indicated because of a high rate of subacute occlusion. We report a single-center registry including 190 patients stented with 2.5 mm balloons. Procedural success was 98% and subacute occlusion rate was 2.6%. Clinical follow-up showed a 24.5% repeat intervention rate. These results seemed acceptable, warranting stent implantation in small arteries in the case of acute or threatened closure. New stent designs and coatings may contribute to the improvement of outcomes and to the decrease in subacute occlusion and restenosis rates.
