One area of potential change may be that focal areas causing pressure loss within a vessel could be specifically targeted for intervention. Presently, coronary intervention is typically performed from normal-to-normal segments with a view to avoid geographical miss, which has been associated with higher rates of target vessel revascularisation, myocardial infarction; imaging studies with IVUS have suggested stent edge plaque burden and geographical miss are associated with early stent thrombosis and restenosis [14,15]. However, it is also known that excessive stent length is associated with increased lumen loss, which may itself have further implications [16].
