Recent trials showed potential clinical benefit of fractional flow reserve (FFR) application in patients with severe aortic stenosis undergoing transcatheter aortic valve implantation (TAVI),1,2 however, the optimal FFR cut-off point still remains unclear in this clinical setting. Advances in computational methods facilitated non-invasive physiological assessment from coronary computed tomography angiography (CCTA), that may be especially beneficial in patients undergoing TAVI, allowing for the …

Response to “Reassessing the role of serum phosphate in coronary artery calcification progression”
We sincerely appreciate the thoughtful comments by Dr. Birgün and colleagues regarding our recently published article examining the association between serum phosphate and coronary artery calcification (CAC) progression.1,2 Their correspondence raises several important considerations that allow us to clarify the intention and scope of our analyses.

Assessment of calcium characteristics in chronic total occlusion using computed tomography coronary angiogram and implications for percutaneous coronary intervention
Calcification in a chronic total occlusion (CTO) is better visualised on Computed Tomography Coronary Angiography (CTCA) than invasive angiography.

2025 ACC/AHA/ASE/ASNC/SCCT/SCMR Advanced Training Statement on Advanced Cardiovascular Imaging
Since the publication of its first Core Cardiovascular Training Statement (COCATS) in 1995,1 the American College of Cardiology (ACC) has defined the knowledge, experiences, skills, and behaviors expected of clinical cardiologists. Subsequent revisions have moved toward competency-based training based on the 6-domain competency structure promulgated by the Accreditation Council for Graduate Medical Education (ACGME) and the American Board of Medical Specialties and endorsed by the American Board…

CT-derived computational modelling in the lifetime management of aortic stenosis
Lifetime management of aortic stenosis represents a growing procedural and clinical challenge. With recent clinical trials indicating that transcatheter aortic valve replacement (TAVR) is at least on par with surgical aortic valve replacement (SAVR) in treating lower risk patients, there has been a rise in TAVR uptake in younger, lower risk patients, leading to an increased likelihood of bioprosthetic valve degradation within a patient’s lifetime. This shift in treatment has changed the landscap…

Assessment of left ventricular thrombi using cardiac CT: A comparative evaluation of non-contrast, CT-angiography, delayed-enhanced images, and extracellular volume maps
CT-derived extracellular volume mapping and delayed-phase imaging significantly outperform non-contrast and early-phase CT in detecting left ventricular thrombi, providing superior diagnostic accuracy and enhancing clinical decision-making.

A “CCTA guided-ICA” approach in patients with a previous history of CABG: An exploratory metanalysis
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…

Reassessing the role of serum phosphate in coronary artery calcification progression
We read with great interest the article by Kim et al., “The role of serum phosphate and calcium levels in coronary artery calcification progression,” which reported that even physiologic phosphate concentrations are independently associated with accelerated coronary artery calcification progression.1 While this large, multicenter analysis contributes valuable longitudinal data, several interpretative and methodological aspects merit further scrutiny before inferring causality.

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 …
