“…Our average contrast delivery over the course of the study has been 68.3 ± 6.2 cc (N = 88), not including any test bolus given beforehand. This contrast usage is similar to or less than what is typically used for cardiac CT scanning [20,21]. While it is important to note that the patient may receive additional contrast during the interventional procedure on top of that delivered during the rotation, it will be necessary to document the impact on the overall contrast delivered since it is feasible that the presentation of a 3D reconstruction will reduce the number of subsequent angiograms needed.…”

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.

Objective: Though successful transcatheter closure has been reported in secundum atrial septal defect (ASD) with deficient posterior-inferior rim, it is still difficult to screen the appropriate candidates. Three-dimensional printing (3DP) makes in vitro trial occlusion possible, and might provide a feasible method in the prediction of successful closure.Methods: Thirty-five consecutive ASD patients (10M/25F, age, 47.7 AE 11.8 years) with deficient posterior-inferior rim (≤3 mm) were referred for attempted transcatheter closure, and personalized heart model (elastic rubber) was produced based on end-systolic MSCT images. The in vitro measurement and trial occlusion were performed for preoperative evaluation (in vitro successful/unsuccessful group), and the results were compared with postoperative outcomes. Results: Successful in vitro occlusion was achieved in 30 patients (7M/23F), and the size of ASD was 27.1 AE 4.4 mm. The posterior-inferior rim was 0.95 AE 1.22 mm (rim defect in 17 patients), and 12 patients were associated with aortic rim deficiency. The subsequent transcatheter closure was performed successfully in 29 patients, and the occluder-diameter was identical to that of in vitro occlusion (35.0 AE 4.4 mm). The follow-up (1.4 AE 0.58 years) showed no residual shunt and related-complications. In unsuccessful in vitro group (n = 5), the range of rim deficiency was wider (P = 0.019) and the rim to inferior vena cava was shorter (4.60 AE 2.07 mm vs. 10.71 AE 5.28 mm, P = 0.016). Furthermore, transcatheter closure failed in all patients.Conclusions: In ASD with deficient posterior-inferior rim, 3DP allows accurate determination of the size and surrounding rims of ASD. Based on personalized heart model, in vitro trial occlusion is an effective method to identify the appropriate candidates for transcatheter closure.

“…One example of this is for atrial septal defects and aorta stenosis. Quaife et al (260) showed that CT images actually had a higher correlation with the actual size of a septal defect than those of transesophageal echocardiography done to assess atrial septal defects with balloon sizing using intracardiac echocardiography, the reference standard.…”

Korean Guidelines for the Appropriate Use of Cardiac CT

et al. 2015

View full text Add to dashboard Cite

The development of cardiac CT has provided a non-invasive alternative to echocardiography, exercise electrocardiogram, and invasive angiography and cardiac CT continues to develop at an exponential speed even now. The appropriate use of cardiac CT may lead to improvements in the medical performances of physicians and can reduce medical costs which eventually contribute to better public health. However, until now, there has been no guideline regarding the appropriate use of cardiac CT in Korea. We intend to provide guidelines for the appropriate use of cardiac CT in heart diseases based on scientific data. The purpose of this guideline is to assist clinicians and other health professionals in the use of cardiac CT for diagnosis and treatment of heart diseases, especially in patients at high risk or suspected of heart disease.
