“…Rotational angiography (RA) for cardiac applications was first described in 1998 and was developed to improve both diagnostic and therapeutic interventions in cardiac disease [1]. RA can be performed with an image intensifier or flat detector system.…”

Imaging modalities utilized in the interventional cardiology suite have seen an impressive evolution and expansion recently, particularly with regard to the recent interest in three-dimensional (3D) imaging. Despite this, the backbone of visualization in the catheterization laboratory remains two-dimensional (2D) X-ray fluoroscopy and cine-angiography. New imaging techniques under development, referred to as three-dimensional rotational angiography (RA) and C-arm CT, hold great promise for improving current device implantation and understanding of cardiovascular anatomy. This paper reviews the evolution of rotational angiography and advanced 3D X-ray imaging applications to interventional cardiology.

“…Early observational data have suggested that contrast and radiation exposure may be reduced with the use of a single anteroposterior (AP) rotation of the imaging camera while providing similar percent stenosis image information [12][13][14]. These findings have not been previously corroborated in any randomized study.…”

This study evaluates the safety and clinical utility of rotational angiography in the diagnosis of coronary artery disease. High-speed rotational angiography is a newly available angiographic modality that gives a dynamic multiple-angle perspective of the coronary tree during a single contrast injection. We prospectively randomized 56 patients referred for diagnostic coronary angiography to either standard or rotational angiography. Contrast and radiation utilization were compared between the two groups. The number of additional cine acquisitions needed was used to determine adequacy of the diagnostic study protocol. Rotational angiography was successfully completed in all subjects. There was a 33% reduction in contrast utilization in the rotational group as compared to the standard group (35.6 +/- 12.6 vs. 52.8 +/- 10.7 ml, respectively; P < 0.0001). Additionally, there was a 28% reduction in total radiation exposure in the rotational group as compared to the standard group (39.0 +/- 18.5 vs. 53.9 +/- 23.4 Gycm(2), respectively; P = 0.01). Total whole-body radiation exposure to the primary operator was 144 mrem with rotational angiography and 170 mrem with standard angiography. Procedure time tended to be shorter for rotational angiography (353.9 +/- 146.7 vs. 396.8 +/- 165.8 s; P = 0.3). Rotational coronary angiography can be rapidly performed in any patient and provides a significant reduction in contrast and radiation utilization while at the same time providing adequate angiographic data to complement or replace standard coronary angiography in the evaluation of coronary artery disease.

“…Tommasini et al [8], using a manually rotated C-arm method, identified lesions that appeared to be critical on rotational angiography but were categorized as noncritical or insignificant with conventional methods. Rotational X-ray coronary angiography has also been implemented in a preliminary form on a conventional image intensifier system [9].…”

We designed and implemented a digital flat-panel-based rotational X-ray coronary angiography technique hypothesizing that luminal disease could be identified with less radiation exposure and contrast usage compared to conventional angiography. Individuals scheduled for diagnostic coronary angiography were prospectively enrolled. In addition to conventional acquisitions in standard planes, subjects underwent one additional left coronary artery (LCA) or right coronary artery (RCA) rotational (spin) acquisition using a predefined trajectory. Radiation exposure and contrast volume were recorded for each run. Seventy-five subjects were enrolled. When compared with standard five-view cine acquisition, LCA spin angiography with one cranial and one caudal run resulted in 34.38% +/- 13.65% less radiation, 18.98% +/- 4.97% less contrast, and comparable assessment of stenosis severity. One spin acquisition compared with three standard cine acquisitions for RCA angiography resulted in 59.31% +/- 29.07% lower radiation, no significant change in contrast, and comparable assessment of stenosis severity. Rotational X-ray coronary angiography provides comparable visualization of coronary anatomy compared with traditional nonrotational coronary angiography with significantly less radiation exposure and contrast volume.
