Procedure: Percutaneous coronary intervention
Registration Number
NCT06567938
Lead Sponsor
First Affiliated Hospital Xi'an Jiaotong University
Brief Summary

The IVUS-CKD study is a prospective, randomized controlled, multicenter trial to determine whether the intravascular ultrasound (IVUS)-guided percutaneous coronary intervention is superior to the angiography-guidance in chronic kidney disease (CKD) patients with respect to target vessel failure (TVF) at 12 months after randomization.

GroupInterventionDescription
Angiography-guidance PCIPercutaneous coronary interventionAngiographic success is defined as thrombolysis in myocardial infarction (TIMI) flow grade 3, and residual stenosis \< 20%.
IVUS-guidance PCIPercutaneous coronary interventionIn the IVUS-guidance group, the optimal stent deployment criteria for non-left main lesion will include the following: : (1) the minimal lumen area (MLA) in the stented segment \> 5.0 mm\^2 or \> 90% of the MLA at the distal reference segments, (2) plaque burden 5 mm proximal or distal to the stent edge is \< 55%, and (3) absence of medial dissection over 3 mm in length. In the setting of a two-stent approach for distal left main bifurcation lesions, the optimal stent deployment criteria are an absolute minimal stent area (MSA) greater than 8 mm\^2 for the left main, greater than 7 mm\^2 for carina, greater than 6 mm\^2 for the ostial or proximal left anterior descending artery, and greater than 5 mm\^2 for the ostial or proximal left circumflex artery. For left main lesion treated with single-stent technique, the criteria are greater than 7mm\^2 for distal and greater than 8mm\^2 for proximal. Further treatment will be required if the criteria are not met.
Primary Outcome Measures
NameTimeMethod
Target vessel failure (TVF), including cardiac death, target vessel myocardial infarction (MI), or clinically driven target vessel revascularization (TVR)12 months

The difference in TVF will be calculated from 0 month to 12 months between IVUS- and Angiography-guidance groups.

Secondary Outcome Measures
NameTimeMethod
Hierarchical composite of target vessel failure12 months

Hierarchical composite of cardiac death, target vessel MI, or clinically driven target vessel revascularization after randomization analyzed by win ratio method.

30-day cardiorenal endpoint30 days

A composite of contrast-associated acute kidney injury (CA-AKI), requiring specific treatment for acute renal failure, persistent decline in eGFR, MI, or all-cause death.

Cardiac death12 months

Death that could not be attributed to a noncardiac etiology is considered cardiac death.

Target vessel MI12 months
Clinically driven target vessel revascularization12 months

Any clinically driven repeat percutaneous intervention or surgical bypass of any segment of the target vessel including the target lesion.

Spontaneous MI12 months
Target vessel failure excluding periprocedural MI12 months

The difference will be calculated from 0 month to 12 months between IVUS- and Angiography guidance groups.

Clinically driven target lesion revascularization12 months
Target lesion failure12 months

A composite of cardiac death, target vessel related MI, or clinically driven target lesion revascularization.

Major adverse cardiovascular event12 months

A composite of cardiac death, MI, definite stent thrombosis (ST), or clinically driven TVR
