The
routine use of intracoronary stents to reduce acute complications and
improve the clinical outcome of percutaneous coronary intervention is
now well established, with a reduction in the complications of acute
closure, myocardial infarction, and emergency surgery, as well as the
six month restenosis rate by up to 50%.1-3 However, with
the continued incidence of subacute stent thrombosis and the fact that
a six month clinical restenosis rate of 10-20% still exists, this
suggests that stenting, particularly in "non-Benestent" lesions,4 is less than perfect. Initial experience with
coronary stent deployment was characterised by a high thrombosis rate
despite aggressive anticoagulant regimens, which increased the risk of early vascular complications.5 6 Improvements in clinical outcomes followed from the use of antiplatelet rather than
anticoagulant drugs,7 better stent designs, and the
evidence from intravascular ultrasound (IVUS) of suboptimal stent
expansion with lower pressure deployment. Studies using the latter
technique showed that full stent
