Abstract:Objective To evaluate the impact of intravascular ultrasound imaging (IVUS) guidance on the final volume of contrast
agent utilized in patients undergoing percutaneous coronary intervention (PCI). Methods A total of 83 patients were randomized
grouped to angiography-guided PCI group and IVUS-guided PCI group. The primary endpoint was the total volume contrast agent
used during PCI. Patients were followed clinically for an average of 4 months. Results The median total volume of contrast was 64.5
mL in angiography-guided group vs. 20.0 mL in IVUS-guided group (P<0.001). Similarly, the median volume of contrast/creatinine
clearance ratio was significantly lower than patients who were treated with IVUS-guided PCI (P<0.001). The in-hospital and 4-month
outcomes were not different between the two groups. Conclusion The tilization of IVUS as the primary imaging tool is safe to guide
PCI, and markedly reduces the volume of iodine contrast, compared to angiography-alone guidance. The use of IVUS should be
considered for patients at high risk for contrast-induced acute kidney injury or volume overload undergoing coronary angioplasty.
