Use of the DyeVert system in chronic total occlusion percutaneous coronary intervention

Background. Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) often requires administration of large contrast volume. The DyeVert system (Osprey Medical) is a disposable, Food and Drug Administration (FDA)-approved device that interfaces with standard manifold systems to reduce the amount of contrast used in cardiac catheterization. Methods. We compared the procedural outcomes of patients in whom the DyeVert system was used vs those in whom it was not used during CTO-PCI at a single center between 2017 and 2018. Results. The DyeVert system was used in 39 of 134 CTO-PCIs performed in 130 patients (30%). Most patients (79%) were men and the mean age was 66.6 ± 10.9 years. The most common target vessel was the right coronary artery (54.5%), followed by the left anterior descending artery (26.1%), and circumflex artery (15.7%). The median contrast volume used in DyeVert patients was significantly lower (200 mL [interquartile range, 153-256 mL] vs 250 mL [interquartile range, 170-303 mL]; P=.04). There were no in-hospital major complications with the DyeVert system, nor device-related procedural complications. One patient in the DyeVert group had contrast-induced nephropathy following CTO-PCI that did not require dialysis. Conclusion. Use of the DyeVert system is feasible during CTO-PCI and may reduce the contrast volume administered to the patient. Additional larger studies with a primary clinical endpoint are needed to confirm these findings.
