Effectiveness and Luminal Changes of Rotablator without Adjunctive PTCA for Calcified Stenosis Associated with Coronary Aneurysm of Kawasaki Disease

Background; Highly calcified stenosis associated with coronary aneurysm is often noted in Kawasaki disease.These lesions are difficult to treat by balloon angioplasty or stenting because of their anatomical characteristics. The porpose of this study is to evaluate the efficacy of Rotablator without additional balloon angioplasty to avoid vessel damage. Method; 11lesions of 7 patients (LMT 1, LAD 10;12.3 ±2.1yrs;male 6, female 1) were treated by Rotablator without additional balloon angioplasty. All cases were evaluated postoperatevely,3,6,and12months later by angiography and IVUS. Results; All procedures were successful. No angiographic or clinical restenosis was noted in the follow-up period (8.6 ±4.4months). Final burr size is 2.0±0.2mm. Angiographic result is summerized as Table 1. Conclusion; Rotablator without additional balloon angioplasty would be an effective to treat highly calcified stenosis associated with coronary aneurysm in Kawasaki disease,providing no angiographic or clinical restenosis in 12 months after the procedureTable 1Angiographic Result
