Abstract
AimsThe most prominent procedure-related and thus modifiable risk factor for contrast-induced acute kidney injury is contrast media (CM) volume. The DyeVert™ system has been designed to reduce the amount of CM. The primary objective of this randomised controlled trial was thus to examine whether the novel DyeVert™ contrast reduction system (Osprey Medical Inc., Minnetonka, MN, USA) leads to a reduction in CM volume in patients undergoing diagnostic coronary angiography. MethodsPatients scheduled for a diagnostic coronary angiogram were randomised to angiography with or without the DyeVert™ system. The primary efficacy endpoint was mean CM volume. Image quality was evaluated by an independent reviewer blinded to treatment allocation. ResultsA total of 96 patients underwent randomisation. Baseline characteristics were well balanced between groups. Use of the DyeVert™ system resulted in a significant 41.0% reduction in CM volume (36.9±10.9mL versus 62.5±12.7mL, p<0.001). Image quality using the DyeVert™ system was non-inferior compared to control (p=0.03). There were no device-related adverse events. ConclusionsThe DyeVert™ system leads to significant reduction in CM volume in patients undergoing diagnostic coronary angiography, while maintaining image quality.
