Table 5 IVUS stent lengths vs manufacturer box-stated stent length

From: Longitudinal stent elongation or shortening after deployment in the coronary arteries: which is dominant?

  Box-stated length E-E length p A-A length p* Average IVUS length p
Elongated stent group, mm 19.3 ± 5.7 21.2 ± 6.2 <0.001 20.7 ± 6.3 <0.001 19.7 (16.2–24.3) <0.001
Shortened stent group, mm 19.9 ± 4.7 18.5 ± 4.3 0.05 18.2 ± 4.4 0.04 17.4 (14.7–22.7) 0.001
  1. Data provided as mean ± SD or median (IQR)
  2. A-A length area-to-area stent length, E-E length edge-to-edge stent length, IVUS intravascular ultrasound
  3. *p denotes A-A stent length vs box-stated stent length
  4. p denotes average IVUS stent length vs box-stated stent length [in the elongated stent group = 19.7 (16.2–24.3) vs 18.0 (15–23) and in the shortened stent group = 17.4 (14.7–22.7) vs 18.0 (15.8–23.8)]
