Key result
Rotational atherectomy achieved higher procedural success than PTCA (85% vs 78%, P=0.038) in complex coronary lesions, but 6-month restenosis rates were similar (49% vs 51%, P=0.33).
Why the study?
Does rotational atherectomy improve procedural success, restenosis rates, or major cardiac events compared to balloon angioplasty in patients with complex coronary lesions?
Population
502 patients with angiographically pre-defined complex coronary artery lesions
Comparison
Rotational atherectomy (rotablation) vs Percutaneous transluminal coronary angioplasty
Design
RCT, randomized
Follow-up
6 months

Absolute Event Rate: 85% vs 78%
p-value: p=0.038
Rotational atherectomy yields higher initial procedural success than balloon angioplasty for complex coronary lesions, but long-term clinical and angiographic outcomes at 6 months are comparable.
Thorsten Dill (2000) conducted an RCT in Complex coronary artery lesions (n=502). Rotational atherectomy vs. Percutaneous transluminal coronary angioplasty (PTCA) was evaluated on Procedural success (p=0.038). Rotational atherectomy achieved higher procedural success than PTCA (85% vs 78%, P=0.038) in complex coronary lesions, but 6-month restenosis rates were similar (49% vs 51%, P=0.33).
