Engage guide catheter and advance guidewire into the coronary artery without using contrast. IVUS-guided PCI can reduce the contrast load. Perform co-registration of distal and proximal radio-opaque marker bands of intravascular ultrasound (IVUS) catheter. Deploy the stent at the target lesion under fluoroscopic guidance of these co-registered position of the IVUS-marking images. Complete the ULCPCI procedure with a final angiography using minimal contrast. Newer contrast sparing techniques and intravascular imaging technologies provide opportunities to perform ULCPCI efficiently with good results and the least complicationsUltra-low contrast PCIZero contrast PCIContrast-induced acute kidney injuryIVUS-Guided PCIPCI in Chronic kidney diseaseJournal ArticleIndiaDepartment of Cardiology, Fortis Malar Hospital, Adyar, Chennai, India
