title: In vitro examination of the safety of rotational atherectomy of side branches jailed by stents.
abstract: In vitro experimental models of branch orifices jailed by various stents were created to estimate the safety and the efficacy of rotational atherectomy when rotational burrs were advanced through the struts of stents. The scaffolding structures of the stents were destroyed due to loss and deflection of the struts, and the size of ablated stent-particles differed: the maximal size was 1.7 mm in slotted stents, and 17.6 mm in coiled stents. Thus, there is a definite potential for ablating stents when rotational atherectomy of restenotic lesions of side-branch orifices jailed by stents is performed.
