Coronary stenting is justified by the prevention of acute angioplasty accidents (more or less occlusive, extensive dissection) and by their clearly established value in particular cases (chronic occlusion, venous graft, elastic recoil). Other clinical situations, such as prevention of restenosis are not absolute indications for first-line stenting and some techniques assessing the coronary functional appearance (Doppler, pressure) could select candidate patients for stenting. The choice of stent depends on the type of coronary lesion and each team's experience, bearing in mind that the ideal stent, which does not exist, should combine radial force, softness, good visibility, preservation of collateral vessels, and must be atraumatic and inexpensive. Finally, when the remodelling component of restenosis has been eliminated by stenting, the next step will be to limit or even prevent intrastent intimal hyperplasia by attractive techniques, which still need to be evaluated (intracoronary radiotherapy, gene therapy, etc.).
