Optimization of image sampling rate to lower the radiation dose of dynamic myocardial CT perfusion
Background: Dynamic myocardial CT perfusion (CTP) has emerged as a potential strategy to combine anatomical and functional evaluation in a single modality. However, this method results in a high radiation dose.Methods: Dynamic CTP was performed in 56 patients with suspected or known ischemic heart disease of whom 48 had complete CT-data. Datasets with reduced sampling rate of 2- and 3 RR-intervals (2RR and 3RR) were constructed post hoc. Myocardial blood flow (MBF) estimates from the 2RR and 3RR datasets were compared with estimates based on the full dataset (1RR) using the two one-sided test of equivalence for paired samp...

Pericoronary adipose tissue CT attenuation and its association with serum levels of atherosclerosis-relevant inflammatory mediators, coronary calcification and major adverse cardiac events
Increased attenuation of pericoronary adipose tissue (PCAT) around the right coronary artery (RCA) derived from coronary CTA might detect coronary inflammation. We investigated a potential association between RCA PCAT attenuation and serum levels of atherosclerosis-relevant cytokines and MACE (coronary revascularization, myocardial infarction and/or cardiac death).

Following the Evidence: The Pre-eminent Role of Coronary CT Angiography in 2021
Eleven years ago, the first Appropriate Use Criteria (AUC) for the clinical use of cardiac computed tomography (CCT) was published.1 That document, largely based on expert opinion and studies that primarily assessed the diagnostic accuracy coronary CT angiography (CTA) compared to invasive coronary angiography (ICA), summarized for the field the utilization of CCT across a number of established and potential clinical indications. The 2010 AUC has proven to be highly prescient despite being, at the time, limited by lack of mature evidence for the use of coronary CTA in many of the considered scenarios. (Source: Journal of C...

CTA Pulmonary Artery Enlargement in Patients With Severe Aortic Stenosis: Prognostic Impact After TAVR
Identifying high-risk patients who will not derive substantial survival benefit from TAVR remains challenging. Pulmonary hypertension is a known predictor of poor outcome in patients undergoing TAVR and correlates strongly with pulmonary artery (PA) enlargement on CTA. We sought to evaluate whether PA enlargement, measured on pre-procedural computed tomography angiography (CTA), is associated with 1-year mortality in patients undergoing TAVR.

The Evolving Role of Coronary CT Angiography in Acute Coronary Syndromes
In the United States, non-obstructive coronary disease has been on the rise and each year nearly one million adults suffer myocardial infarction, 70% of which are non-ST-segment elevation myocardial infarction (NSTEMI). In addition, approximately 15% of patients suffering NSTEMI will have subsequent readmission for a recurrent acute coronary syndrome (ACS). While invasive angiography remains the standard of care in the diagnostic and therapeutic approach to these patients, these methods have limitations that include procedural complications, uncertain specificity in diagnosis of the culprit lesion in patients with multi-ve...

Cardiac Computed Tomography in the Contemporary Evaluation of Infective Endocarditis
Increasing data have accumulated on the role of Cardiac Computed Tomography (CCT) in infective endocarditis (IE) with high accuracy for large vegetations, perivalvular complications and for exclusion of coronary artery disease to avoid invasive angiography. CCT can further help to clarify the etiology of infective prosthetic valve dysfunction (e.g. malposition, abscess, leak, vegetation or mass). Structural interventions have increased the relevance of CCT in valvular heart disease and have amplified its use. (Source: Journal of Cardiovascular Computed Tomography)

Association of Neutrophil-to-Lymphocyte Ratio with Non-calcified Coronary Artery Burden in Psoriasis: Findings from an Observational Cohort Study
Inflammation in the form of elevated high-sensitivity c-reactive protein (hs-CRP) has been shown to be critical in the development of atherothrombosis. Psoriasis, a chronic inflammatory skin disease, is associated with high systemic-inflammation, elevated neutrophil-to-lymphocyte ratio (NLR) and accelerated non-calcified coronary artery burden (NCB) by coronary computed tomography angiography (CCTA).

Diagnostic Performance of Cardiac Computed Tomography versus Transesophageal Echocardiography in Infective Endocarditis: a Contemporary Comparative Meta-analysis
Data regarding the comparison of diagnostic accuracy of TEE and CCT for diagnosing IE are limited. The present meta-analysis compares the diagnostic performance of the two imaging modalities for a variety of complications of IE in the same patient populations. Our results show that both TEE and CCT have good diagnostic accuracy, with TEE showing superiority in detecting leaflet defects and CCT performing better in prosthetic valve endocarditis. CCT also showed a trend towards higher sensitivity than TEE for detection of periannular complications. These findings suggest that CCT is a useful adjunct to TEE for IE, whenever a...

Clinical Impact of Mitral Calcium Volume in Patients Undergoing Transcatheter Aortic Valve Implantation
Mitral annular calcification (MAC) has been associated with mitral valve (MV) disease and cardiovascular events in patients undergoing transcatheter aortic valve implantation (TAVI). We aimed to investigate the incidence and impact of mitral calcium volume (MCV) quantified by multidetector computed tomography (MDCT) on MV function and clinical outcomes after TAVI.

Early Effects of Transcatheter Edge-to-Edge Leaflet Repair for Tricuspid Regurgitation: First-in-Human Experience with Computed Tomography
The feasibility of transcatheter tricuspid valve repair (TTVr) with the TriClip system (Abbott Structural, Menlo Park, CA) has been demonstrated with safe and effective tricuspid regurgitation (TR) reduction and improvement in quality of life (1). The TriClip device reduces TR via approximation of the tricuspid leaflet edges to enhance coaptation in a similar fashion of MitraClip device, but with a modified delivery system. Mitral annulus remodeling has been described after MitraClip treatment (2), but little is known about the TriClip effects on the geometry of the tricuspid annulus.

Effectiveness of Point-of-Care Oral Ivabradine for Cardiac Computed Tomography
Coronary CT angiography (CCTA) is increasing seen as a first line investigation in patients with suspected coronary artery disease. Heart-rate control improves the image quality and diagnostic accuracy of CCTA. Typically, beta-blockers are administered to induce sinus bradycardia. Sinus bradycardia may also be induced by ivabradine. We hypothesized that in a real-world population ivabradine would be an effective alternative to metoprolol at heart rate lowering for CCTA.

Does the ISCHEMIA Trial Provide the Appropriate Cohort to Compare Anatomical and Physiologic Testing?
Since the presentation and subsequent publication of the International Study Of Comparative Health Effectiveness With Medical And Invasive Approaches (ISCHEMIA) trial, multiple intense debates erupted in the medical press and on social media on the implications of these findings on clinical practice.1 This landmark randomized clinical trial attempted to investigate whether revascularization in addition to optimal medical therapy could lower events in patients with moderate to severe ischemia on physiologic imaging.
