Does Cutting Balloon angioplasty improve angiographic outcomes in patients with ostial lesions of the left anterior descending artery compared to conventional balloon angioplasty?
Cutting Balloon angioplasty may be more effective than conventional balloon angioplasty for treating ostial lesions of the left anterior descending artery, yielding better acute gain and lower late restenosis.
May enhance acute angiographic outcomes in ostial LAD lesions; leaves open need for RCTs before practice change.
We evaluated the effectiveness of Cutting Balloon angioplasty for ostial lesions of the left anterior descending artery compared with conventional balloon angioplasty. Cutting Balloon angioplasty (n = 7) produced larger acute gain (1.70 ± 0.37 vs 0.48 ± 0.25 mm, P < 0.001) and smaller late loss index (0.54 ± 0.55 vs 1.32 ± 0.81, P < 0.05) than conventional balloon angioplasty (n = 7). As a result, late restenosis was seen in only two patients undergoing Cutting Balloon angioplasty, but in all seven patients undergoing conventional balloon angioplasty. Ostial lesions of the left anterior descending artery may be one of the suitable targets of Cutting Balloon angioplasty. (J Interven Cardiol 2000;13:7–14)
