Efficacy and safety of dual-axis rotational coronary angiography versus conventional angiography Background Conventional coronary angiography (CA) is the gold standard for the diagnosis of coronary artery disease. However, this technique requires several orthogonal projections to determine the severity of the disease. Dual-axis rotational coronary angiography (DARCA) is a new technique which allows visualization of each coronary artery using a single contrast injection and obtains unique images. This technique has been shown to reduce both radiation and contrast exposure. Objective To determine the amount of contrast used, radiation exposure and diagnostic accuracy of DARCA compared to conventional CA. Methods We conducted a prospective, self-controlled study of consecutive patients undergoing elective coronary angiography to compare DARCA versus the conventional technique. All the angiographies were reviewed by two independent interventional cardiologists (observer 1 and observer 2) who evaluated agreement between both types of images. The observers evaluated firstly the DARCAs and three weeks later the conventional CAs to prevent bias in reading the images. Results The contrast volume used in the diagnostic procedure was significantly lower with DARCA (33.29±11.2 ml vs. 17±5.4 ml; p <0.01). Radiation exposure in patient (235.6±76.8 mGy vs. 82.7±46.6 mGy; p <0.01) and operator was also significantly lower (5.7±3.26 mSv vs. 2.48±1.47 mSv; p <0.04). A slight difference and a strong correlation were seen in the number of lesions, vessel diameter and percentage of stenosis between both observers and in both methods. Agreement for categorizing percentage of stenoses was also adequate. Conclusion DARCA reduces the use of contrast agent and radiation exposure compared to the conventional technique without modifying the diagnostic accuracy of the method.
