Stent recoil: comparison of the Wiktor-GX coil and the Palmaz-Schatz tubular coronary stent.
Wiktor-GX coil stents and Palmaz-Schatz 154A tubular stents were implanted in a consecutive series of 40 patients and 45 arteries undergoing successful primary stent placement in de novo lesions treated with single stents in order to compare the acute recoil of a coil stent to a tubular stent in native coronary arteries. Acute stent recoil was determined by measuring the difference between the maximum inflated diameter of the stent deployment balloon and the minimum lumen diameter after stent deployment. There was no difference between the two groups for reference vessel diameter, nominal balloon diameter, maximum inflated balloon diameter, maximum inflation pressure, or poststent vessel minimum lumen diameter. Acute recoil averaged 0.15 +/- 0.2 mm for the Wiktor-GX and 0.13 +/- 0.1 for the Palmaz-Schatz (P = 0.58). In this series of patients, there was no significant difference between the acute recoil of the coil stent compared to the tubular stent.
