Recent advances in cardiovascular risk assessment: The added value of non-invasive anatomic imaging
In 2022, multiple original research studies were conducted highlighting the utility of coronary artery calcium (CAC) imaging in young individuals and provided further evidence for the role of CAC to improve atherosclerotic cardiovascular disease (ASCVD) risk assessment. Mean calcium density was shown to be a more reliable predictor than peak density in risk assessment. Additionally, in light of the ACC/AHA/Multispecialty Chest Pain Guideline's recent elevation of coronary computed tomography angiography (CCTA) to a Class I (level of evidence A) recommendation as an index diagnostic test for acute or stable chest pain, seve...

Increased CT angiography-derived extracellular volume fraction predicts less benefit in left ventricular remodeling and ejection fraction after transcatheter edge to edge repair for severe mitral regurgitation
Mitral regurgitation (MR) is the most common valvular pathology in the United States, with an estimated prevalence of approximately 4 million with significant disease.1 Even in asymptomatic patients, worsening MR severity is associated with impaired survival.

Analysis of tricuspid annulus dimensions and RCA-proximity with artificial intelligence-based software for procedural planning of percutaneous tricuspid annuloplasty
With the exception of edge-to-edge tricuspid repair, currently available transcatheter approaches for tricuspid regurgitation (TR) require pre-procedural computed tomographic (CT) planning with a full-cycle cardiac computed tomography.1 Direct transcatheter tricuspid valve annuloplasty (TTVA) with the Cardioband ® System (Edwards, Irvine, CA) is a safe and effective treatment strategy which is mimicking surgical repair with annular reduction resulting in significant symptomatic benefit for TR patients.

Massive dilation of the right atrium causes dyspnea and gastrointestinal symptoms
A 49-year-old female patient with known primary right heart failure was admitted to the emergency department. The etiology of right ventricular failure is unknown but may be caused by postcapillary pulmonary hypertension as she had had mechanical mitral valve replacement for stenosis before. At presentation, she suffered from progressive physical limitation, dyspnea, lack of appetite as well as from pain and discomfort in the left upper abdomen. Echocardiography revealed a massively dilated right ventricle and atrium. (Source: Journal of Cardiovascular Computed Tomography)

No evidence of coronary plaque stabilization by allopurinol in patients with acute coronary syndrome
Allopurinol, a xanthine inhibitor that lowers uric acid concentration, has been proven to reduce inflammation and oxidative stress in patients with cardiovascular disease. This prospective, single-center, randomized, double-blind study aimed to investigate whether allopurinol therapy could improve plaque stabilization in acute coronary syndromes (ACS) patients using coronary computed tomography angiography. The primary efficacy endpoint was the change in low-attenuation plaque volume (LAPV) from baseline to the 12-month follow-up. Compared with placebo, allopurinol therapy did not signi ﬁcantly alter LAPV (−13.4 ±...

As outlined in my previous presidential page, the evidence base demonstrating that the use of coronary CT angiography (CCTA) reduces cardiovascular mortality is now unequivocal, both in well-designed trial settings and from evidence derived from very large real-world datasets.

Changes in use of preventive medications after assessment of chest pain by coronary computed tomography angiography: A meta-analysis
In our meta-analysis, we found that patients experiencing chest pain undergoing CCTA receive a higher rate of preventive medications, as aspirin and statins, in comparison to those selecting cardiac stress testing. Furthermore, among individuals with plaque identified during the CCTA, there is a significantly elevated prescription rate for these medications when contrasted with patients showing no plaque in the exam. These findings emphasize the potential advantages of CCTA in guiding more effectiveness in preventive treatment strategies for individuals with chest pain.

Optimal diagnostic approach for using CT-derived quantitative flow ratio in patients with stenosis on coronary computed tomography angiography
This prospective diagnostic accuracy study enrolled 404 de novo chest pain patients with at least one 50 % diameter stenosis by visual estimation on primary coronary CTA. In these patients CT derived quantitative flow ratio (QFR) had a high discrimination and good accuracy for identifying hemodynamically obstructive CAD at invasive coronary angiography. Using lesion-specific CT-QFR had incremental diagnostic value compared to most distal CT-QFR. CT-QFR identified most cases of hemodynamically obstructive CAD while a normal CT-QFR excluded hemodynamically obstructive CAD in the majority of patients. (Source: Journal of...

Predictors of percutaneous coronary intervention derived from CCTA in patients with chronic coronary syndrome
Coronary CT Angiography (CCTA) has become an established tool in the diagnostic work-up of patients with a low-to-intermediate likelihood of coronary artery disease (CAD), allowing the evaluation of anatomical, morphological, and functional plaque features. CCTA could aid decision-making for treatment strategy. We derived a CCTA score (CT-PCI score) based on plaque anatomy and morphology able to predict PCI referral in a cohort of patients undergoing CCTA for suspected CAD, with FFRCT available, referred to invasive coronary angiography and physiological assessment. The AUC of the score was 0.80 (95%CI 0.74 –0.86), sensi...
