Editorial Coming close and then pulling away

This editorial refers to ‘Late incomplete apposition after drug-eluting stent implantatioin: incidence and potential for adverse clinical outcomes ’ by Siqueira et al., doi:10:1093/eurheartj/ehm114 Interventional cardiologists have focused great interest and resources on vascular healing. The obvious reasons for this interest relate to what happens after vascular segments have been manipulated—expanded, stretched, cracked, or other-wise broken—during percutaneous intervention. The earliest energies focused on what happened after balloon dilatation alone. There were four possibilities: (i) a significant dissection developed which disrupted flow and resulted in acute or threa-tened closure, (ii) the artery was initially stretched but then recoiled within the first 24 h, (iii) the artery healed after the initial injury but then developed neointimal hyperplasi
