Patient-specific valve-in-valve computational modelling to guide the index TAVR procedure
Transcatheter aortic valve replacement (TAVR) is often used to treat severe aortic stenosis in younger patients with a longer life expectancy. These patients may out live their index transcatheter aortic valve (TAV) and Heart Teams must anticipate and plan for future redo-TAVR. This includes the choice of TAV used and its deployment position which may potentially preclude future redo-TAVR and coronary access. New models to assess and mitigate the risk of coronary obstruction or inaccessibility in TAV-in-TAV are needed prior to performance of the index procedure (see Fig.  1).

Prognostic utility of the pericoronary fat attenuation index in patients with takotsubo cardiomyopathy
The etiology of takotsubo cardiomyopathy (TCM) remains poorly understood and no optimal management strategy has been established. Identification of features associated with poor outcomes may improve the prognosis of patients with TCM. We aimed to identify the predictors of poor prognosis in patients with TCM using coronary computed tomography angiography (CCTA). (Source: Journal of Cardiovascular Computed Tomography)

Rationale and design of the INVICTUS Registry: (Multicenter Registry of Invasive and Non-Invasive imaging modalities to compare Coronary Computed Tomography Angiography, Intravascular Ultrasound and Optical Coherence Tomography for the determination of Severity, Volume and Type of coronary atherosclerosiS)
The INVICTUS registry is a multicenter, retrospective, and prospective study designed to evaluate the dimensions of coronary arteries, as well as the characteristic, volume, and phenotype of coronary atherosclerosis by CCTA, compared with the invasive imaging modalities including intravascular ultrasound (IVUS), near-infrared spectroscopy-IVUS and optical coherence tomography. The main objective of the INVICTUS registry is to achieve a high diagnostic performance of CCTA and a more in-depth evaluation of the phenotype of coronary atherosclerosis. Our findings will potentially shed new light on precision medicine informed b...

Stent-frame decoupling following self-expandable transcatheter aortic valve replacement
In 2009, Shultz et  al.1 analysed multidetector computed tomography (MDCT) scans of 30 patients following first-generation CoreValve (CRS, Medtronic, Luxembourg) implantation and demonstrated that incomplete and non-uniform expansion of the transcatheter aortic valve (THV) stent frame could be observed at all prosthe sis levels. However, they also found a high level of eccentricity in the left ventricle outflow tract (LVOT) and native annulus, and less deformity in the middle and higher THV segments.

SCCT Past, Present, and Future – It’s All About the People
It is a privilege to take over the presidency of the Society of Cardiovascular CT, a special society born from the development of a new field of cardiovascular imaging almost two decades ago. The initial vision of Stephan Achenbach and colleagues, who set up the Society and pioneered the field of cardiovascular CT, set the path to a truly international community that remains inclusive, warm, energetic, and welcoming.

Ultra-high-resolution CT —Has the future arrived?
While claims for “high-resolution” CT have been made for years—often based on software improvements without proof of actual improved spatial resolution—the term “ultra-high-resolution” CT (or UHR-CT) has been defined by Koweek et al. in this issue based on hardware characteristics, i.e., a detector width of 0.25 mm or less. Given that CT spatial resolution is closely linked to detector width, decreasing the latter does indeed lead to improved ability to differentiate greater detail compared to conventional CT technology.

Pericoronary adipose tissue attenuation is associated with non-calcified plaque burden in patients with chronic coronary syndromes
Pericoronary adipose tissue attenuation (PCAT) is a marker of inflammation of the pericoronary fat tissue, which can be assessed by coronary computed tomography angiography (CCTA). Its prognostic value was reported in previous studies. Nevertheless, the relationship between PCAT, plaque burden and coronary artery disease (CAD) severity, are not well defined.

Calcium scoring on coronary computed angiography tomography with photon-counting detector technology: Predictors of performance
Acquiring accurate virtual non-iodine (VNI) images from coronary artery CT angiography datasets could decrease both acquisition time and radiation dose associated with routine calcium scoring. In the current paper, the in-vivo agreement of Agatston scores obtained with a novel spectral reconstruction VNI algorithm and with conventional true non-contrast (TNC) images were investigated and potential predictors of performance were identified. The investigation revealed that VNI-based calculations correlate significantly with TNC calcium scores, demonstrating substantial agreement. On the other hand, increased tube voltage pro...

A systematic review of contrast-enhanced computed tomography calcium scoring methodologies and impact of aortic valve calcium burden on TAVI clinical outcomes
This systematic review examines the role of aortic valve calcification (AVC) on transcatheter aortic valve implantation (TAVI) outcomes. Sixty-eight studies were included, reporting varied methodologies for quantifying AVC. AVC quantification methodology with contrast-enhanced CT was found to be variable. A positive association between calcium burden and increased risk of adverse outcomes, including permanent pacemaker implantation, paravalvular leak, and aortic rupture, was reported. AVC negatively impacts TAVI outcomes independently of the quantification method. (Source: Journal of Cardiovascular Computed Tomography)

Proposed competencies for the performance of cardiovascular computed tomography in pediatric and adult congenital heart disease
Cardiovascular computed tomography (CCT) is rated appropriate by published guidelines for the initial evaluation and follow up of congenital heart disease (CHD) and is an essential modality in cardiac imaging programs for patients of all ages. However, no recommended core competencies exist to guide CCT in CHD imaging training pathways, curricula development, or establishment of a more formal educational platform. To fill this gap, a group of experienced congenital cardiac imagers, intentionally inclusive of adult and pediatric cardiologists and radiologists, was formed to propose core competencies fundamental to the exper...

Comparison of the rate of change (slopes) in impact factor of medical imaging journals unveils journals with organic growth: An observational study (2016 –2022)
On June 2023, the Clarivate Analytics Journal Citation Reports (JCR) electronic platform published the annual Impact Factor (IF) of the year 2022 for its indexed journals. The IF has been used as a quality measurement for journals. IF is commonly an essential criterion when authors choose where to submit their articles; therefore, it is a necessary measure for the researcher and the author community.1 As bibliometrics is one of our group's investigation lines, we have observed and published exciting behaviors.

AI-based, automated chamber volumetry from gated, non-contrast CT
Cardiac chamber volume is known to be an excellent predictor of future heart failure events. According to recent guidelines, gated, non-contrast cardiac CT (NCCT) is recommended for CAD screening in asymptomatic individuals at low to intermediate risk. We validated a novel, fully automated, AI based method for cardiac chamber volume and myocardial mass quantification from gated NCCT scans used for coronary calcium scoring. NCCT based volume quantification shows excellent agreement with the volumes obtained from CCTA scans in the same patient. Thus, volume assessment from NCCT scans acquired for calcium scoring appears feas...
