“…The use of 3D‐DRA in CHD was first described by Glatz (11). The advantages of 3D‐DRA are (i) convenience of performing tomographic imaging in the cardiac catheterization lab instead of a radiology suite; (ii) tomographic imaging from 3D‐DRA provides details that are not obtainable using biplane cine‐angiography; (iii) selection of optimal camera angles prior to a planned intervention; (iv) accurate registration of the 3D‐image to live fluoroscopy as the image is acquired under the same conditions compared with a computed tomography (CT) or MRI . However, the utility of 3D‐DSRA has not been studied during cardiac catheterizations for CHD.…”

“…Initially, because of concerns of excess radiation to obtain 3D‐DRA, its use was limited to complex interventional procedures. Technological changes have made the radiation dose to obtain 3D‐DRA similar to bi‐plane cine‐angiography allowing its routine use in congenital cardiac interventions. However, these lower dose protocols require larger contrast volumes to be injected to obtain diagnostic quality 3D‐DRA.…”

“…Additionally, despite deep sedation, patient motion or respiratory artefacts were still possible. Furthermore, although the radiation dose is an important concern, significant reduction of the effective radiation dose during rotational angiography is also possible with novel protocols [16].…”

SUMMARYAim: Rotational angiography is a well-known method for the three-dimensional (3-D) reconstruction of left atrium and pulmonary veins during left-sided atrial arrhythmia ablation procedures. In our study, we aimed to review our experience in transseptal puncture (TSP) using 3-D rotational angiography. Methods: We included a total of 271 patients who underwent atrial fibrillation ablation using cryoballoon. Rotational angiography was performed to get the three-dimensional left atrial and pulmonary vein reconstructions using cardiac C-arm computed tomography. The image reconstruction was made using the DynaCT Cardiac software (Siemens, Erlangen, Germany). Results: The mean age of the study population was 61 AE 10 years. The indications for left atrial arrhythmia ablation were paroxysmal AF in 140 patients (52%) and persistent AF patients in 131 (48%) patients. The success rate of TSP using only rotational guidance was (264/271 patients, 97.4%). In the remaining seven patients, transesophageal guidance was used after the initial attempt due to thick interatrial septum in five patients and difficult TSP due to abnormal anatomy and mild pericardial effusion in the remaining two patients. Mean fluoroscopy dosage of the rotational angiography was 4896.4 AE 825.3 lGym 2 . The mean time beginning from femoral vein puncture to TSP was 12.3 AE 5.5 min. Conclusion: TSP guided by rotational angiography is a safe and effective method. Our results indicate that integration of rotational angiographic images into the real-time fluoroscopy can guide the TSP during the procedure.

“…The effective radiation dose for 4DRA, calculated by patient-specific Monte-Carlo simulation, was 5.1 ± 1.1 mSv in Wielandts study [21]. De Buck et al state that three-dimensional rotational angiography is possible with a significant reduction in the effective dose without compromising image quality [11]. To reduce the effective dose they dropped the frame rate from 248 to 67 and 45 frames.…”

Objectives: To compare the image quality, accuracy and effective dose of the default diagnostic program with the low dose program. Methods: The diagnostic and low dose programs of three-dimensional rotational angiography were compared considering their signal to noise ratio, their carrier to noise ratio and their actual radiation dose in μGy·m²/kg. An anthropomorphic phantom underwent both types of scans to evaluate the effective dose. Comparative measurements of vessel diameters were taken in the diagnostic and the low dose program and compared to the angiography as exact basis. The image quality of the scans using the different programs was rated by a specialist physician. Results: The low dose scan does use significantly less radiation and still provides images, which are adequate for 3D navigation of catheter-based interventions. Conclusion: Three-dimensional rotational angiography can be applied with the low dose program and is sufficient for 3D navigation.
