Key result
Higher institutional volume is linked to ~44% fewer major complications after rotational atherectomy.
Observational (n=13,335)
Yes
Rotational atherectomy has a low overall major complication rate of 1.3%, which is significantly reduced when performed at high-volume institutions.

Rotational atherectomy carries low major complication rates that decrease at higher-volume centers; observational data leaves open causal volume thresholds.
Sakakura et al. (2016) conducted an observational in Percutaneous coronary intervention requiring rotational atherectomy (n=13,335). Rotational atherectomy was evaluated on Composite of in-hospital death, cardiac tamponade, and emergent surgery after rotational atherectomy. Major procedure-related complications after rotational atherectomy occurred in 1.31% of cases, with higher institutional volume associated with lower risk (OR 0.56; 95% CI 0.36-0.89).
