Abstract: |
The purpose of this study is to evaluate the relationship between vessel size and outcome of directional coronary atherectomy (DCA). Patients who underwent DCA for lesions in native coronary arteries were included. Reference vessel size was quantitatively measured using a computer assisted system. Based on reference vessel size (VS), lesions were categorized in 5 groups: VS 2.0(<2.25mm). VS 2.5 (2.25–2.75mm), VS 3.0 (2.75–3.25mm), VS 35 (3.25–3.75 mm) and VS 4.0 (≥3.75mm). The outcome of DCA was as follows:VS 2.0VS 25VS 3.0VS 35VS4.0pLesions242357303187146Acute outcomeVDR0.961.201.391.581.88<0.009DCA success93%92%93%91%95%n.s.Perforation0.4%0.3%0.3%0%0.7%n.s.CABG1.2%2.8%3.0%4.3%1.4%n.s.Tissue (mg)12.513.914.218.014.7<0.001% residual14%14%14%19%19%<0.001Restenosis (6 month)Primary53%47%38%24%20%<0.001Restenosed57%49%39%34%28%0.03VDR: Vessel device ratio |
