  Purpose
Most doctors who use the new drug-eluting stents for the treatment of long coronary narrowings tend to cover the full length of the lesion with long or multiple stents. The investigators hypothesized that a policy of spot-stenting, i.e., stenting of only the very tight parts of the coronary narrowing, might result in better outcomes by means of avoiding multiple stents that have been associated with significant complications such as late stent thrombosis.

Detailed Description:
Coronary artery lesion length is an independent predictor of restenosis following coronary intervention and the deployment of multiple or long bare metal stents has been associated with an increased risk of adverse clinical outcome. Spot stenting, ie discrete stenting of only the most severe stenoses of long, diffuse lesions has been proposed as an alternative in this clinical setting. The introduction of drug-eluting stents has resulted in longer lesions being stented and the use of multiple, overlapping DES in patients with diffusely diseased coronary arteries has been considered safe and effective. However, there has also been evidence of increased major adverse cardiac events (MACE) with the use of multiple, overlapping DES,10-12 while long DES have been associated with increased probability of intraprocedural stent thrombosis.13 We hypothesized that an approach based on spot-stenting with the use of DES might result in superior clinical outcomes compared to full cover of atheromatic lesions with long or multiple stents. We are therefore conducting a randomized comparison of spot versus multiple overlapping stenting on consecutive patients with long (>20 mm) lesions and indications for percutaneous coronary intervention.
