Key result
Rotational atherectomy was associated with a lower 1-year survival rate compared to non-rotational atherectomy (89.6% vs 97.7%, p<0.005), reflecting the higher baseline comorbidities in the RA group.
Why the study?
Limited data were available on the effect of rotational atherectomy plus stenting in the treatment of complex calcified coronary artery lesions.
Does rotational atherectomy plus stenting improve short and long-term outcomes compared to standard PCI in patients undergoing percutaneous revascularization?
Cohort (n=16,009)
No

Absolute Event Rate: 89.6% vs 97.7%
p-value: p=<0.005
Rotational atherectomy for complex calcified lesions yields high procedural success comparable to standard PCI, though lower 1-year survival reflects the significantly higher baseline comorbidities in this patient population.
No takes yet. Share an insight, caveat, or question.
Survival difference likely reflects comorbidities; leaves open whether rotational atherectomy independently affects outcomes in calcified lesions.
Sayami et al. (2021) conducted a cohort in Obstructive coronary artery disease requiring percutaneous coronary intervention (n=16,009). Rotational atherectomy vs. Non-rotational atherectomy PCI was evaluated on 1-year survival (p=<0.005). Rotational atherectomy was associated with a lower 1-year survival rate compared to non-rotational atherectomy (89.6% vs 97.7%, p<0.005), reflecting the higher baseline comorbidities in the RA group.
