Comparison between a dedicated stent positioning system and conventional stenting of aorto-ostial lesions: a prospective, multi-center, randomized controlled study

ABSTRACT:

Background

The accurate placement of stents for treatment of coronary aorto-ostial lesions (AOLs) is technically challenging. The purpose of this study was to evaluate the efficacy and safety of a stent positioning system with a dedicated nitinol device and compare them with those of the conventional approach for stenting of coronary AOLs.

Methods

In this prospective, multi-center, open-label, randomized study, conducted from November 2015 to April 2019, patients with coronary AOLs that underwent percutaneous coronary intervention (PCI) were randomly allocated (allocation ratio 1:1) using block randomization method to either a stent positioning system group or a conventional technique group. The primary endpoint was the range of stent slippage when positioning. The follow
