Summary: Ultra-low contrast percutaneous coronary interventions (ULPCIs) aim to reduce the risk of contrast-induced nephropathy (CIN) after angiography. Intravascular imaging, particularly intravascular ultrasound (IVUS), offers a promising option for ULPCIs by allowing lesion recognition and characterization without the need for contrast injection.

Summary: A novel technique for accurate ostial stent placement using real-time IVUS guidance has been developed. Benchtop testing showed clear differences in appearance between the stent and other components of the delivery system on IVUS. Real-time IVUS guidance during stent placement reduces the distance between the stent edge and ostium effectively.

Summary: Advancements in stent technology and endovascular devices have improved the safety and effectiveness of second-generation drug-eluting stents. However, in-stent restenosis and stent thrombosis still pose challenges in percutaneous coronary intervention. Recent studies have highlighted the value of intravascular imaging in identifying causes of stent failure and guiding therapy.

Summary: This study investigated the efficacy of the bumper wire technique combined with intravascular ultrasound (IVUS) assessment in aorto-ostial interventions. The results showed that this technique is safe and efficient, with low rates of geographic miss and adverse clinical outcomes.

Summary: Using intravascular ultrasound (IVUS), this study aimed to clarify the cause of in-stent restenosis (ISR) in the ostium of the right coronary artery (RCA). The main mechanisms found were neointimal hyperplasia, neoatherosclerosis, uncovered ostium, stent fracture or deformation, stent underexpansion, and protruding calcified nodules. Half of the ISR cases were due to mechanical causes, and treating mechanically caused ISR without new stent implantation led to a higher subsequent event rate.

Summary: The analysis of published data showed that intravascular volume expansion is effective in preventing CA-AKI, with intensive IV volume expansion further decreasing the risk of CA-AKI.

Summary: In patients with multiple exposures to contrast media, deterioration of renal function over time is associated with known risk factors for kidney disease progression, but not with cumulative contrast volume.

Summary: This study investigated the effects of contrast media (CM) viscosity on renal tubules using a kidney-on-a-chip model. The results showed that under static and low-to-moderate shear stress conditions, low-osmolar contrast media (LOCM) induced more cell injury compared to iso-osmolar contrast media (IOCM). However, under high shear stress conditions, there was no difference in cell injury between LOCM and IOCM.

Summary: This article describes a novel technique that eliminates uncertainty during PCI procedures and achieves the highest precision in stent positioning, arguably even better than with the use of angiography. The technique involves using IVUS guidance alongside stent placement, simplifying low contrast PCI procedures and increasing confidence in precise stent implantation.

Summary: This study aimed to investigate the association between contrast-enhanced ultrasound (CEUS) findings and kidney function. CEUS examinations were conducted on 30 living kidney donors, and various perfusion parameters were analyzed. The results showed that mean signal intensity (MeanLin) had a significant correlation with kidney function, especially in normal-weight individuals. These findings suggest that CEUS signal intensity may be influenced by body mass index (BMI).

Summary: This study aimed to investigate the association between immediate incomplete stent apposition (ISA) detected by intravascular ultrasound (IVUS) and midterm stent failure. The results showed that immediate ISA detected by IVUS was significantly associated with midterm stent failure. Therefore, we should pay attention to reduce immediate ISA for improving midterm outcomes.

Summary: The study in Taiwanese patients found that contrast-enhanced CT was associated with a higher risk of acute kidney injury and further hemodialysis in patients with impaired kidney function, but not in those with normal kidney function.

Summary: The net benefit of percutaneous coronary intervention (PCI) in patients with chronic kidney disease (CKD) is not well established. However, proper management is crucial to improve outcomes for this patient population, including pre-procedural preparation, reducing contrast usage during the procedure, implementing modern strategies, and personalized antithrombotic therapy.
