Atherectomy was performed in 133 patients (139 lesions) before stenting (group I), while 187 patients (201 lesions) underwent stent implantation without debulking (group II). At one-year follow-up, target lesion revascularization (TLR) was 19.4% for group I and 18.2% for group II (p = 0.47). There was no difference in cumulative death or Q wave myocardial infarction between the groups. These results suggest that, in most patients with SVG aortoostial lesions, debulking before stent implantation may not be necessary.

The restenosis rate was lower in the DCA-stent group (n=27) than in the stent-alone group (n=47) (20% versus 43%, respectively).

Effectiveness of rotational atherectomy of right coronary artery ostial stenosis

Two years after intervention, target lesion revascularization rate was 16%. Predictors of symptomatic angiographic restenosis were dissection >10 mm, final minimal luminal diameter <2.5 mm, lesion length >10 mm, restenotic lesion, and diabetes. In conclusion, rotational atherectomy of right coronary ostial stenosis results in excellent acute procedural success and in low incidence of clinical recurrence, with a high proportion of patients remaining angina-free 2 years after intervention.

Report of two cases in which the tips of guide catheters were damaged by rotational burrs during rotational coronary atherectomy of aorto- ostial lesions. There were no signs of embolization caused by the material of the guide catheters during and after the interventions

Stent placement for ostial left anterior descending coronary artery stenosis: acute and long-term (2-year) results

111 consecutive patients with ostial LAD stenting were included for this study. Angiographic restenosis rate at 6 month FU was 26.1% (18/69), and target lesion revascularization rate 11.7%. The final luminal diameter after stenting was the only predictor of angiographic restenosis. In conclusions, stenting with or without debulking atherectomy may be considered as an acceptable therapeutic option for the treatment of ostial LAD stenosis.
