Contrast-induced nephropathy (CIN) after coronary angiography or intervention is associated with substantial morbidity. The data supporting various prophylactic measures and adjunctive therapies to prevent this complication are conflicting. However, contrast volume is clearly related to CIN after percutaneous coronary intervention (PCI), and the risk of CIN has been shown to be directly related to contrast dose. Therefore, minimizing contrast exposure is a primary method to reduce the risk of CIN, especially in at-risk patients. We report a novel technique designed to deliver ultra-low (<15 cm(3)) volume contrast to patients with chronic kidney disease undergoing coronary angiography and PCI.
