Abstract
The CrossFlexTM stent is a flexible, balloon-expandable new device with an excellent flexibility,
radial strength, and conformability. The aim of this study was to evaluate the safety and efficacy of the new
CrossFlex stent in the treatment of native coronary artery diseases. Methods:The CrossFlexTM stent was implanted
in 328 consecutive patients (mean age 60±10, M/F=2.6:1) with the 345 lesions. Stent deployment was
accomplished with a single inflation to 14–16 atmospheres without adjunct high-pressure balloon dilatation
(single high pressure technique). Intravascular ultrasound (IVUS) imaging was performed to evaluate the results
of stent deployment in selected patients. Results:The indications for stent implantation were elective in 304
lesions (88.1%), suboptimal angioplasty results in 15 lesions (4.4%), and threatened or acute vessel closure in
26 lesions (7.5%). Procedural success rate was 99.1%, and nonfatal myocardial infarction occurred in 3 patients
(0.9%) after stent deployment. The minimal lumen diameter increased from 0.8±0.4 to 3.2±0.5 mm, and the
diameter stenosis decreased from 74±13 to 0.5±9%. IVUS was performed in 40 lesions at the time of stent
implantation. The IVUS images after stenting seemed to be more like slotted-tube stents than coil stents. Mild
plaque prolapse within the stent occurred in 3 lesions. There were no lesions of incomplete stent apposition
using single high-pressure technique. Conclusions:The CrossFlexTM stent is a safe and effective device with a
high procedural success rate for treatment of native coronary artery disease. Further studies may be needed to
assess late clinical outcomes of this stent.
