[Recanalization of complete coronary occlusions followed by STENT implantation. An angiographic study after 6 months].

The restenosis and reocclusion rate after coronary recanalization by conventional angioplasty are high. The role of stent implantation in this context is unknown. The authors assessed a group of 49 patients who underwent implantation of one or more stent after a recanalization procedure by angiography at 6 months. The restenosis rate assessed by quantitative angiography was 24%; no cases of reocclusion were observed. These angiographic results were accompanied with a significant improvement of the anginal symptoms (p < 0.01). These results suggest that stent implantation following recanalization of a coronary occlusion may be beneficial on the restenosis and reocclusion rates and anginal symptoms. However, they should be confirmed by randomised study. It would also be important to analyse the impact of this procedure on the outcome of left ventricular function.
