Lesions at the ostium of the left anterior descending coronary artery constitute a distinct group because of suboptimal results and higher restenosis rate after balloon angioplasty. Several non-balloon devices have been used to improve the outcome of dilatation of such lesions. We retrospectively compared the in-hospital and follow-up results of directional coronary artherectomy and stents for the treatment of ostial lesions of the left anterior descending artery. Out of 37 patients, 12 underwent directional coronary atherectomy and 25, stent implantation. The two strategies were deployed at different periods over the past five years. The baseline clinical and angiographic characteristics were comparable in the two groups. Directional coronary atherectomy was done using 7Fr atherocath with adjunctive balloon angioplasty in all. All the stents were deployed using moderate to high pressure balloon inflation after adequate predilatation. While the pre-procedure luminal diameter stenosis was similar in the two groups (87.3 +/- 8.8% vs 89.3 +/- 7.2%; p = NS), the residual stenosis was significantly lower in the stent group (5 +/- 2.8%) compared to directional coronary atherectomy (18.7 +/- 9.8; p = 0.02). There was no significant difference in the primary success rate between the two devices (91.6% directional coronary atherectomy vs 100% stent; p = NS). One patient in the directional coronary atherectomy group developed acute closure followed by emergency coronary artery bypass graft surgery and death. No major complication was observed in the stent group. Over a mean follow-up of 9.9 +/- 11.6 months following directional coronary atherectomy and 8.6 +/- 4.4 months after stenting, significantly higher number of patients (60%) developed recurrence of angina or any event following directional coronary atherectomy compared to stent (15.8%; p < 0.02). There was no myocardial infarction, coronary artery bypass graft surgery or death in either group on follow-up. The need for target lesion revascularisation was significantly higher in the directional coronary atherectomy group (50%) compared to stenting (10.5%; p < 0.02). Comparing directional coronary atherectomy with stent, the event-free survival was 80 percent vs 94.7 percent at three months and 50 percent vs 84.7 percent, both at six and nine months, respectively. In conclusion, stenting of the left anterior descending artery ostial lesion results in a significantly lesser post-procedure residual stenosis, improved in-hospital outcome, a lesser need for target lesion revascularisation and much improved event-free survival on follow-up as compared to directional coronary atherectomy. Therefore, stenting appears to be a more favourable treatment option compared to directional coronary atherectomy for the treatment of ostial lesions in the left anterior descending artery.
