Rationale and design of the Dynamic Coronary Roadmap for Contrast Reduction (DCR4Contrast) in PCI randomized controlled trial - 11/08/23
Riassunto |
Background |
The clinical and anatomic complexity of patients undergoing percutaneous coronary interventions (PCI) has increased significantly over the past 2 decades. Contrast induced nephropathy (CIN) significantly impacts prognosis after PCI, therefore minimizing the risk of CIN is important in improving clinical outcomes. Dynamic Coronary Roadmap (DCR) is a PCI navigation support tool which may decrease CIN by projecting a motion-compensated virtual coronary roadmap overlay on fluoroscopy, potentially reducing iodinated contrast volume during PCI.
Study design and objectives |
The Dynamic Coronary Roadmap for Contrast Reduction trial (DCR4Contrast) is a multi-center, prospective, unblinded, stratified 1:1 randomized controlled trial investigating if DCR use reduces the total contrast volume administered during PCI compared to PCI performed without DCR guidance. DCR4Contrast aims to recruit 394 patients undergoing PCI. The primary end point is the total undiluted iodinated contrast volume administered during the PCI, performed with or without DCR. As of November 14, 2022, 346 subjects have been enrolled.
Conclusions |
The DCR4Contrast study will investigate the potential contrast-sparing effect of the DCR navigation support tool in patients undergoing PCI. By reducing iodinated contrast administration, DCR has the potential to contribute to reduced risk of CIN and thus increase PCI safety.
