Background

The incidence of chronic stent recoil of currently available stents is not well known.

Methods

The incidence and degree of both diffuse and focal stent recoil during 6 months follow-up were evaluated in 52 Cypher, 64 Taxus, 61 Endeavor and 50 Driver stents using 3 dimensional intravascular ultrasound (IVUS) data.

Results

The overall incidence of diffuse and focal stent recoil was 3.5 % and 1.8 % , respectively. No difference was found in the incidence of stent recoil among all stents evaluated. The degree of recoil was not correlated with the amount of neointima.

Conclusions

Analysis of serial IVUS volumetric data revealed a low incidence of chronic stent recoil among current generation stents.
