The use of the retrograde approach to treat chronic total occlusion (CTO) has improved overall success rate in this lesion subgroup. Its use to treat complex non-CTO lesions unable to be revascularized by an antegrade approach has not been described. We report a case of the use of the retrograde approach to recanalize a non-CTO lesion under Impella support in a patient with critical stenosis and poor left ventricular function. The retrograde approach may be an alternate pathway in selected non-CTO lesions where the antegrade has been unsuccessful.
