Key result
Rotational atherectomy shows no benefit over balloon angioplasty for procedural success or restenosis.
Why the study?
The comparative immediate and long-term angiographic effects of PTCA versus high-frequency rotational atherectomy (PTCR) in complex coronary artery lesions were not well established.
Does high-frequency rotational atherectomy improve immediate and long-term angiographic outcomes compared to balloon angioplasty in patients with complex coronary artery lesions?

Does high-frequency rotational atherectomy improve immediate and long-term angiographic outcomes compared to balloon angioplasty in patients with complex coronary artery lesions?
Absolute Event Rate: 80% vs 76%
p-value: p=0.260
In complex coronary lesions, rotational atherectomy and balloon angioplasty yielded comparable procedural success and restenosis rates, though balloon angioplasty resulted in a better net luminal gain at 6 months.
No takes yet. Share an insight, caveat, or question.
Lesion characteristics showed no differential procedural impact between PTCA and PTCR; leaves open optimal device selection for complex lesions in contemporary practice.
Dietz et al. (2001) conducted an RCT in Complex coronary artery lesions (n=502). High-frequency rotational atherectomy (PTCR) vs. Balloon angioplasty (PTCA) was evaluated on Procedural success (p=0.260). High-frequency rotational atherectomy yielded comparable procedural success (80% vs. 76%, P=0.260) and 6-month restenosis rates (37% vs. 35%, P=0.658) compared to balloon angioplasty.
