Incidence, predictors, and consequences of coronary dissection following high-speed rotational atherectomy.
The incidence of dissection following rotational atherectomy was 12.8%. By multivariate analysis tortuosity, primary and non-type B lesions were correlated with an increased incidence of dissection. The procedural success rate was reduced in the presence of dissection (86% vs 96%; p = 0.0001) primarily because patients with dissection required coronary bypass more frequently than those without dissection.
