Clinical Trial Summary

This study is designed to investigate whether IVUS-guided DK crush stenting technique compared to angiography-guided DK crush after the indexed procedure will lead to lower rates of the composite endpoint of target vessel failure (TVF) at 12 months. The individual components of TVF include cardiac death, target-vessel myocardial infarction (MI), or target vessel revascularization (TVR). Complex bifurcation lesions were defined according to DEFINITION study.


Clinical Trial Description

This is a prospective, multi-center, randomized-controlled, single blind, superiority trial that will include 35 international sites. The investigators aim to enroll 556 subjects with complex coronary bifurcation lesions in native coronary arterial segments. All patients with complex coronary bifurcation lesions suitable for DES implantation will undergo 1:1 randomization either to IVUS-guided or angiography-guided DK crush stenting using a randomization schedule blocked by site. All subjects will be screened according to the predefined inclusion and exclusion criteria per protocol and will further undergo angiography before DES implantation. Data and images will be collected during the index procedure, during re-intervention in the case of clinically driven TVF, and at the predefined 12-month clinical follow-up visit. All subjects will also undergo angiographic follow-up at 13 months. ;
