We present 6-month follow-up of 435 patients undergoing stent deployment. Forty-four patients were referred because of myocardial ischemia related to the stented artery. In six of these patients (14%), the stented vessel revealed a new proximal lesion separated from the stented portion, which warranted further intervention. It is felt that these new lesions are related to the stenting technique as a result of local trauma induced from the guiding catheter.
