Aims: Cardiac magnetic resonance-derived myocardial strain metrics are emerging as powerful early imaging biomarkers for the detection of cardiac dysfunction. This study utilized the UK Biobank to evaluate: 1) Best practice for measurement of 'rapid longitudinal shortening', a simplified software-independent measure of longitudinal left ventricular (LV) deformation, 2) correlation and agreement of rapid longitudinal shortening and feature tracking (FT) strain, and 3) their respective prognostic value.

Methods And Results: Two rapid longitudinal shortening (long-axis shortening, LS; atrioventricular junction shortening; AVJS) and three FT strain measures (global longitudinal strain, GLS; global circumferential strain; global radial strain) were derived.

Aims: Automated algorithms are regularly used to analyse cardiac magnetic resonance (CMR) images. Validating data output reliability from this method is crucial for enabling widespread adoption. We outline a visual quality control (VQC) process for image analysis using automated batch processing.

Background: Periodontal disease is the sixth most common disease worldwide and may be a contributory risk factor for cardiovascular disease (CVD).

Objectives: This study utilizes noninvasive cardiac imaging and longitudinal and genetic data to characterize the association between periodontal disease and both cardiovascular magnetic resonance (CMR) imaging biomarkers of remodeling and incident coronary artery disease (CAD).

Methods: From the UK Biobank, 481,915 individuals were included, 91,022 (18.

Article Synopsis
  • * Conducted with data from the UK Biobank, which included extensive genetic, electrocardiogram, and imaging data from nearly 470,000 participants, the study found that 0.1% carried likely pathogenic TTR variants.
  • * Results showed a significant difference in variant prevalence based on ancestry, with a 0.02% prevalence in individuals of European ancestry versus 4.3% in those of African ancestry, highlighting the need for more targeted research and awareness.

Background: Myocardial strain using cardiac magnetic resonance (CMR) is a sensitive marker for predicting adverse outcomes in many cardiac disease states, but the prognostic value in the general population has not been studied conclusively.

Objectives: The goal of this study was to assess the independent prognostic value of CMR feature tracking (FT)-derived LV global longitudinal (GLS), circumferential (GCS), and radial strain (GRS) metrics in predicting adverse outcomes (heart failure, myocardial infarction, stroke, and death).

Methods: Participants from the UK Biobank population imaging study were included.

Aims: Identifying the imaging method that best predicts all-cause mortality, cardiovascular adverse events, and heart failure risk is crucial for tailoring optimal management. Potential prognostic markers include left ventricular (LV) myocardial mass, ejection fraction, myocardial strain, stroke work, contraction fraction, pressure-strain product, and a new measurement called global longitudinal active strain density (GLASED). This study sought to compare the utility of 23 potential LV prognostic markers of structure and contractile function in a community-based cohort.

Article Synopsis
  • The study addresses the lack of population-specific cardiovascular magnetic resonance (CMR) reference ranges, which is important for clinical care.
  • It provides CMR reference ranges based on data from 9,088 healthy individuals, considering age, sex, and ethnicity, thus enhancing the understanding of heart metrics across diverse demographics.
  • The analysis involved advanced software and various imaging techniques, resulting in a comprehensive set of healthy CMR-derived volumetric reference ranges that can be applied in clinical settings.

Background: Diabetes and its cardiovascular complications are a growing concern worldwide. Recently, some studies have demonstrated that relative risk of heart failure (HF) is higher in women with type 1 diabetes (T1DM) than in men. This study aims to validate these findings in cohorts representing five countries across Europe.

Aims: Cardiac amyloidosis is common in elderly patients with aortic stenosis (AS) referred for transcatheter aortic valve implantation (TAVI). We hypothesized that patients with dual aortic stenosis and cardiac amyloid pathology (AS-amyloid) would have different baseline characteristics, periprocedural and mortality outcomes.

Methods And Results: Patients aged ≥75 with severe AS referred for TAVI at two sites underwent blinded bone scintigraphy prior to intervention (Perugini Grade 0 negative, 1-3 increasingly positive).

Background: Diabetes mellitus (DM) is associated with increased risk of cardiovascular disease. Detection of early cardiac changes before manifest disease develops is important. We investigated early alterations in cardiac structure and function associated with DM using cardiovascular magnetic resonance imaging.

Surgical aortic valve replacement remains the therapy of choice in majority of patients with aortic stenosis. Bioprosthetic heart valves are often preferred over mechanical valves as they preclude the need for anticoagulation with its associated risks of bleeding and thromboembolism. However, bioprosthetic heart valves undergo structural deterioration and eventually fail.

The present article reports a case involving a 29-year-old man who developed severe cardiac failure (New York Heart Association class IV). He had a complex surgical history, beginning with the repair of an anterior sinus of Valsalva aneurysm and closure of a ventricular septal defect at eight months of age. His residual Valsalva aneurysm and mixed aortic valve disease necessitated mechanical aortic valve replacement at 14 years of age.

A 12-year-old girl with hypoplastic right heart, double inlet left ventricle, and transposition of the great arteries had a lateral tunnel Fontan operation 8 years previously. She developed symptoms related to a combination of stenosis in the inferior caval venous pathway, a fenestration, and leak in the lateral tunnel. These were successfully treated with a custom-made stent graft.
