简介
Objectives and background
The impact of underexpansion and minimal stent area (MSA) criteria in the second generation drug‐eluting stents (DES) has not been addressed yet.
Methods
Using intravascular ultrasound (IVUS), we assessed the optimal cut‐off values of post‐stenting MSA to prevent in‐stent restenosis (ISR). Poststenting IVUS data and 9‐month follow‐up angiography were available in 912 patients with 990 lesions: 541 sirolimus‐eluting stents (SES), 220 zotarolimus‐eluting stents (ZES) and 229 everolimus‐eluting stents (EES).
Results
For the prediction of angiographic ISR, the MSA of each DES was measured. The poststenting MSA was 6.4 ± 1.8 mm2 in SES, 6.2 ± 2.1 mm2 in ZES and 6.2 ± 2.1 mm2 in EES. At the 9‐months follow‐up, the incidence of angiographic ISR was similar between SES (3.3%) vs. ZES (4.5%) vs. EES. (4.4%), (P = 0.53). Multivariable logistic regression analysis …
