Conclusion

The treatment of aorto-ostial stenotic lesions is technically challenging. The major contributors to the challenge are technical and anatomical. The limitations of angiographically guided stent placement are clearly demonstrated in this study. Inaccurate stent positioning was observed in more that half of the cases. This study is unique among all previous studies examining aorto-ostial lesions, by defining both the incidence of stent misplacement and demonstrating the adverse clinical outcome of a significantly higher rate of TLR associated with stent misplacement. These findings suggest that there is a need for tools or techniques to improve the accuracy of positioning of stents to treat aorto-ostial disease.
