To the Editor Suboptimal stent deployment is a major problem with percutaneous coronary intervention (PCI) and is associated with an increased risk of major adverse cardiac events such as death, stent thrombosis, and target vessel revascularization.1 Intravascular ultrasonography has been effective in optimizing stent deployment,2 but leads to more balloon dilations after stent implantation.
