Clinical angiographic and histologic correlates of eetasia after directional coronary atherectomy

Directional coronary atherectomy can cause ectasia (final area stenosis = 75%, was present in 50% of patients without procedural ectasia and in 70% of patients with marked ectasia (residual area stenosis <-20%; P = 0.12). It is concluded that excision beyond the normal arterial lumen may occur after directional coronary atherectomy, related, in part, to angiographic and procedural features noted at the time of atherectomy. Restenosis tends to occur more often in patients with marked ectasia after coronary atherectomy.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30232/1/0000626.pd
