چکیده
INTRODUCTION AND OBJECTIVES Coronary angiography is the gold standard for the study of coronary artery disease. This technique requires several orthogonal projections. Rotational angiography is a new technique which involves pre-set rotation of the X-ray tube around the patient and allows visualization of each coronary artery in different views, using a single contrast injection. The purpose of this study was to compare conventional coronary angiography (A) vs rotational angiography (B), focusing on radiation dose, amount of contrast administered, and total procedure time for both diagnostic and therapeutic percutaneous coronary interventions. METHODS Prospective study of 104 consecutive patients undergoing coronary angiography who were randomized to one of these techniques. RESULTS We found a significant reduction in the amount of contrast administered (A vs B, 93.1 [41.7] vs 50.9 [14.7] mL; P<.0001) and radiation exposure (27.6 [11.5] vs 18 [6.4] mGycm(2); P<.0001). A significant increase in total procedure time was noted in the rotational angiography arm. However, when only the last 50 patients were analyzed, we found no difference in procedure time between the groups, probably related to the learning curve of the operators. Angioplasty was performed in 29 patients in group A and 28 patients in group B. Contrast reduction was maintained in the rotational angiography group compared to the conventional technique (A vs B, 335.1 [192.1] vs 238.5 [114.4] mL; P=.02). CONCLUSIONS The rotational angiography technique leads to a significant decrease in radiation exposure and contrast dose administered for diagnostic procedures when compared to conventional coronary angiography. In patients who undergo percutaneous coronary intervention, contrast reduction remains significant.

Feasibility evaluation of dual axis rotational angiography (XperSwing) in the diagnosis of coronary artery disease
During coronary angiography, the use of potentially harmful X-ray radiation and iodine contrast agent should be kept to a minimum, without compromising the diagnostic accuracy of the procedure. Coronary angiography is conventionally performed in multiple stationary views at different angles around the patient. A complete X-ray run with contrast injection is made in each view. An alternative to ...

The purpose of this study was to evaluate peak skin dose received by the patient and scattered dose to the operator during dual-axis rotational coronary angiography (DARCA), and to compare with those of standard coronary angiography (SA). An anthropomorphic phantom was used to simulate a patient undergoing diagnostic coronary angiography. Cine imaging was applied on the phantom for 2 s, 3 s, an...
