  1. Shown are the angiographic characteristics of the target lesions of the patients. Plus–minus values are mean ± standard deviation and the curved numbers a represent the known total of which the variable was calculated. b Proximal devices were defined as implantation at lesion segments 1,5,6,11. c Visual estimated diameter stenosis was defined in percent. d Length of lesions, devices and balloons were measured in millimetre (mm) as was the diameter of the devices. e Dilatation and inflation pressures were measured in atmosphere (atm)
