Abstract

Intravascular ultrasound is a usful too to assess the adequate stent strut expansion after stent implantation and nowadays it can bo also used as a dicision making method about omitting anticoagulant therapy. We used intravascular ultrasound before and after Palmz-schatz stent implantation in 3 patients with coronary artery narrowings and analysed serial post porcedure lumen diameter, cross sectional area. We think it is a useful tool to assess the effect of stent implantation and post stent balloon dilatation.
