Abstract:
To compare the safety, radiation dose, and contrast volume between dual axis rotational coronary angiography (DARCA) and conventional coronary angiography (CCA) . Background CCA is performed in multiple, predefined stationary views, at different angulations around the patient, for both the left and right coronary arteries. DARCA (AlluraXperSwing ™ , Philips, the Netherlands) involves a pre‐set rotation of the C‐arm around the patient and allows for the visualization of each coronary artery in different views, using a single automatic pump contrast injection . Methods From November 2012 to February 2013, 201 patients were randomly assigned to either CCA (n = 100) or DARCA (n = 101). Exclusion criteria included acute coronary syndrome (ACS), prior PCI or CABG. CCAs were performed in 4 acquisition runs for the left coronary artery and 2 to 3 acquisition runs for the right coronary artery, whereas DARCAs were performed in a single run for each coronary artery . Results Baseline demographics and clinical characteristics were similar for both groups. The overall prevalence of CAD was 77.6%. The DARCA group had a significant reduction in the amount of contrast, 60 ml (IQR: 52.5–71.5 ml) versus 76 ml (IQR: 68–87 ml), P 〈 0.0001; and radiation dose by Air Kerma, 269.5 mGy (IQR: 176–450.5) versus 542.1 mGy (IQR: 370.7–720.8), P 〈 0.0001. There were fewer patients requiring additional projections in the DARCA group: 54.0% versus 75.0%; P = 0.002 . Conclusions In a population with a high prevalence of CAD, DARCA was safe and resulted in a significant decrease in contrast volume and radiation dose . (J Interven Cardiol 2014;27:456–464)
