Repeat revascularization is required within five years for around 15 % of patients who underwent coronary artery bypass grafting (CABG) due to accelerated progression of coronary artery disease and a high rate of saphenous vein graft failure.1 Anatomical variability in graft origin and course, a greater number of target vessels and the frequent absence of surgical documentation make invasive coronary angiography (ICA) particularly challenging. These factors result in longer procedure times, gre…

Percentage of left ventricular myocardial blood flow distribution and revascularization completeness in FASTTRACK CABG
TOC summary•The novel CCTA-derived LV%MYO method can objectively and individually quantify the amount of myocardium at risk of ischemia in SYNTAX segments downstream of a stenosed coronary artery, enabling the prospective prediction and retrospective assessment of complete revascularization.•In patients with complex coronary artery disease receiving coronary artery bypass grafting, there were significant differences between the fixed and theoretical myocardial blood flow as per the conventional …

Artificial intelligence-guided quantitative coronary CT angiography (AI-QCT) automated detection and occlusion length estimation of chronic total occlusions
Artificial intelligence (AI)-enhanced coronary computed tomography angiography (CCTA) analyses may enhance the detection of chronic coronary total occlusions (CTOs) and facilitate pre-procedural planning for CTO percutaneous coronary intervention (PCI).

Applying dual energy computed tomography to postmortem coronary computed tomographic angiography
Medical examiners’ offices are increasingly utilizing postmortem computed tomography (CT). While dual energy CT (DECT) has been applied in both clinical and postmortem settings, research on the application to postmortem coronary computed tomographic angiography (PMcCTA) is extremely limited. This study aims to evaluate whether DECT performed following PMcCTA using two contrast agents with differing chemical and physical properties allows for agent discrimination and simultaneous characterization…

Preoperative imaging accuracy and resource utilization in sinus venosus atrial septal defects
Sinus venosus atrial septal defects (SVASDs) have a strong association with partial anomalous pulmonary venous return (PAPVR). Symptoms are uncommon in childhood and the diagnosis may be delayed for several years. Surgery is typically postponed to pre-school age as the lesion is well-tolerated. Preoperative follow-up commonly includes periodic transthoracic echocardiograms (TTE) and electrocardiograms (ECG). An important component of preoperative planning includes accurate delineation of PAPVR w…

Photon-counting detector computed tomography for evaluation of coronary artery disease in older adults
Coronary computed tomography angiography (CCTA) in older adults is often limited by heavy coronary artery calcification and associated blooming artifacts. Photon-counting detector CT (PCD-CT) offers higher spatial resolution and reduced artifacts compared with conventional energy-integrating detector CT (EID-CT). We sought to investigate diagnostic performance and clinical impact of PCD-CT in older adults.

Reply: Balancing innovation and evidence: Coronary computed tomography angiography in preoperative valve surgery
We welcome Celik et al.’s1 thoughtful comments on our recent article, “Coronary CT angiography versus invasive angiography for preoperative coronary assessment prior to valve surgery”.2 We appreciate the opportunity to clarify and expand on several important issues they have raised.

The role of serum phosphate and calcium levels in coronary artery calcification progression: A multicenter, longitudinal cohort study
Table of Contents Summary Higher serum phosphate levels within the normal range were associated with a higher likelihood of prevalent CAC, higher baseline CAC scores, and faster longitudinal CAC score progression. The effect of phosphate on CAC progression had a synergistic interaction with baseline CAC scores and serum calcium levels. Our results identify phosphate as a target to slow CAC progression and ultimately to lower cardiovascular risk.
