Abstract

This study sought to investigate the degree of acute recoil of four different stents by means of quantitative coronary angiography. Four hundred and six patients underwent stent implantation for single discrete coronary artery lesion: 105 received a 16 mm Paragon stent, 112 an 18 mm Multilink Duet,97 a 16 mm NIR Prime stent, and 92 a 15 or 18 mm NIR Royal Advance. Elastic recoil was defined as the difference between mean balloon cross-sectionalarea (CSA) at the highest pressure and mean CSA after PTCA. The mean stentrecoil was 13% +/- 10% CSA (P < 0.001), being statistically greater for the nitinol Paragon stent (21% +/- 11%), intermediate for the multicellular Multilink Duet stent (14% +/- 7%), and minimum for the NIR family (9% +/- 6%and 8% +/- 7%, respectively). The recoil was not homogeneously distributedalong the stent length but was lower at the two ends (11% +/- 12% and 13% 11%) and highest in the central part (15% +/- 12%)(P < 0.001). Thus, acute recoil is a significant phenomenon regardless of the mechanical properties and design of new-generation tubular stents. Cathet Cardiovasc Intervent 2001;52:147-153.
