Objectives:  We sought to characterize the use, efficacy, and performance characteristics of premounted stents relative to nonpremounted stents when used during congenital cardiac catheterization. Background:  Endovascular stent implantation is an effective means of relieving vascular obstruction in patients with congenital heart disease. However, stent implantation is technically challenging and important complications occur. Premounted stents appear to offer many advantages relative to their nonpremounted counterparts, and it has been suggested that the use of premounted stents is associated with fewer complications. However, translation of these potential benefits into procedural or clinical success has been poorly examined and the data are conflicting. Methods:  All stent placements performed between January 1, 1999 and December 31, 2009 were reviewed. Analysis of technical success, hemodynamic success and complications was performed. Results:  416 stents were placed over the 10 year period. 158 (38%) were premounted. There was no apparent trend in the frequency of use of premounted stents over the study period. Implanted premounted stents were smaller in diameter than nonpremounted stents 4.9 mm +/- 1.8 versus 13.9 mm +/- 3.7, and the site of stent placement differed significantly. Unadjusted and adjusted analysis of technical success with respect to the precision of stent placement, hemodynamic success, and complications showed no difference between premounted and non-premounted stents. Conclusions:  We found no difference between premounted and nonpremounted stents with respect to procedural and hemodynamic success or complications. Nevertheless, there remain practical advantages to the use of premounted stents that may justify their expanding role in congenital cardiac catheterization. (J Interven Cardiol 2012;**:1-4).
