Key result
DCA before stenting ostial LAD lesions is linked to ~64% lower six-month MACE vs stenting alone.
Why the study?
Does directional atherectomy followed by stenting improve angiographic and clinical outcomes in patients with de novo ostial LAD lesions compared to stenting alone?
Cohort (n=117)
Does directional atherectomy followed by stenting improve angiographic and clinical outcomes in patients with de novo ostial LAD lesions compared to stenting alone?
Absolute Event Rate: 8.7% vs 23.9%
p-value: p=0.048
Directional atherectomy prior to stenting for ostial LAD lesions is safe and significantly improves mid-term angiographic and clinical outcomes compared to stenting alone.

May support directional atherectomy before stenting for ostial LAD; leaves open confirmation in randomized trials before practice change.
F. Airoldi (2003) conducted a cohort in De novo lesions located at the ostium of the left anterior descending coronary artery (n=117). Directional atherectomy (DCA) followed by stent implantation vs. Stenting alone was evaluated on Six month major adverse events (MACE) (p=0.048). Directional atherectomy followed by stenting for ostial LAD lesions significantly reduced six-month major adverse events compared to stenting alone (8.7% vs 23.9%, p=0.048).
