Over 400,000 percutaneous transluminal coronary angioplasties (PTCAs) are currently performed annually in the United States. Approximately 10% of these procedures include rotational atherectomy, although the national average rate of stent placements continues to increase in some centers to as high as 75%. The combination of rotational atherectomy and intra-coronary stent placement is between 2% and 7.5% of interventional procedures per year in the United States. This article reviews the existing literature on rotational atherectomy and stent implantation for complex lesions and describes the upcoming prospective, multicenter randomized Stent Implantation, Postrotational Atherectomy (SPORT) trial.
