Summary
Rotational atherectomy combined with stent implantation is used in complex coronary lesions. The upcoming SPORT trial will evaluate this combination in a prospective, multicenter randomized study.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Devices
Background:
- Over 400,000 percutaneous transluminal coronary angioplasties (PTCAs) are performed annually in the US.
- Rotational atherectomy is used in approximately 10% of PTCAs.
- Stent placement rates are increasing, reaching up to 75% in some centers.
Purpose of the Study:
- To review the literature on rotational atherectomy and stent implantation for complex coronary lesions.
- To describe the upcoming Stent Implantation, Postrotational Atherectomy (SPORT) trial.
Main Methods:
- Literature review of rotational atherectomy and stent implantation.
- Description of the SPORT trial design: prospective, multicenter, randomized.
Main Results:
- The combination of rotational atherectomy and intra-coronary stent placement accounts for 2% to 7.5% of US interventional procedures annually.
- Existing literature on this combination for complex lesions is reviewed.
Conclusions:
- The SPORT trial aims to provide further evidence on the efficacy and safety of rotational atherectomy followed by stent implantation for complex coronary lesions.
