Scholarcy highlights

  • We studied 12 patients undergoing elective coronary stent implantation for either recurrent restenosis or adverse lesion appearance
  • Fractional plaque area remained unchanged from 30 ± 12% after conventional balloon angioplasty to 32 ± 11% after stent implantation
  • In contrast to the substantial improvement in the angiographically assessed residual luminal obstruction after stent implantation compared with the prestent condition, considerably less improvement was found by intravascular ultrasound-assessed examination
  • The inherently different approaches to vascular imaging represented by contrast angiography and intravascular ultrasound techniques appear to provide complementary information
