Comparative StudyIncidental pulmonary nodules in emergent coronary CT angiography for suspected acute coronary syndrome: Impact of revised 2017 Fleischner Society Guidelines.
Pulmonary nodules (PN) are frequently detected incidentally during coronary computed tomography angiography (CTA). We evaluated whether the 2017 Fleischner Society guidelines may result in a decrease of follow-up testing of incidental PN as compared to prior guidelines in patients undergoing coronary CTA. ⋯ Application of the 2017 Fleischner Society Guidelines resulted in a significant decrease of follow-up testing for incidental PN in patients undergoing coronary CTA for suspected acute coronary syndrome.

Leaflet thrombosis following transcatheter aortic valve implantation.
Transcatheter aortic valve implantation (TAVI) is increasingly being offered to high-risk patients with symptomatic aortic valve stenosis. Recent reports have suggested a high incidence of subclinical leaflet thrombosis following bioprosthestic aortic valve replacement. We report the frequency and clinical presentation of leaflet thrombosis identified by cardiac CT in patients referred for follow-up contrast enhanced CT angiography following TAVI. ⋯ Leaflet thrombosis following TAVI is a relatively frequent finding in patients referred for contrast enhanced CT angiography following TAVI. In the majority of patients it follows a subclinical course and is substantially more frequent in individuals who are not on oral anticoagulation. However, in patients with relevant increase in prosthetic gradients, symptomatic presentations are possible.

Cinematic rendering of cardiac CT volumetric data: Principles and initial observations.
Cinematic rendering (CR) a new method of 3D computed tomography (CT) volumetric visualization that produces photorealistic images. As with traditional 3D visualization methods, CR may prove to be of value in providing important information when evaluating regions of complex anatomy such as the heart. ⋯ CR is a promising method to enhance display volumetric CT data and should prove useful in diagnosis, treatment planning, surgical navigation, trainee education, and patient engagement. However, further study is needed to establish the advantaged and disadvantages of CR in comparison to other 3D methods.
