Figure 2: Cumulative distribution curves of diameter stenosis immediately after percutaneous coronary intervention procedure and at follow-up angiography. Percent diameter stenosis after PCI was significantly higher in the ELCA group than in the non-ELCA group (p = 0.02), but there was no significant difference between the groups at follow-up (p = 0.21). ELCA, excimer laser coronary atherectomy; PCI, percutaneous coronary intervention.
