    Title translation Cardiovascular magnetic resonance in clinical practice: who, when and why?
    Abstract Cardiovascular magnetic resonance (CMR) is an imaging modality with growing indications in cardiology. The purpose of this article is to illustrate the current clinical applications of CMR across the spectrum of ischemic heart disease, non-ischemic cardiomyopathies, cardiac arrhythmias and valvular or vascular heart disease. The strengths of CMR lie in its ability to comprehensively image, without the need for ionizing radiation, cardiac and vascular anatomy, function, perfusion, viability and physiology, providing a powerful non-invasive tool for patient diagnosis and prognostication.

    Abstract Hepatic microwave ablation (MWA) is a growing treatment modality in the field of primary and secondary liver cancer. One potential side effect is thermal damage to adjacent structures, including the pericardium if the hepatic lesion is located near the diaphragm. Hemorrhagic cardiac tamponade is known to be a rare but potentially life-threatening complication. Here we present the first case of cardiac complication following MWA treatment in a 55-year-old man who presented with late cardiac tamponade. Adequate and timely management is essential, and clinicians should be fully aware of the need to perform early transthoracic echocardiography to detect signs of pericardial effusion when cardiac involvement is suspected.

    Abstract Background: Lower limb peripheral arterial disease (PAD) is a leading atherosclerotic disease in the elderly. However, awareness of the disease is poor, particularly in women.
    Methods: In this retrospective, cross-sectional study, postmenopausal women referred to our Angiology Division were tested for PAD, defined as an "ankle-brachial index" (ABI) ≤0.9 or ≥1.4 (in the latter case with a "toe-brachial index" <0.7), or a history of lower limb arterial revascularization. Aim of our study was to assess cardiovascular (CV) risk profile in postmenopausal women with and without PAD, and to evaluate the role of PAD and six classic CV risk factors (CVRFs), namely age, current smoking, hypertension, dyslipidaemia, severe chronic renal failure, and diabetes in predicting CV disease (CVD), defined as coronary artery disease and/or cerebrovascular disease.
    Results: Overall, 850 patients were included, 39.4% of whom with PAD. Compared with women without PAD, those with PAD were older (75.2 vs 66 years, respectively; p <0.001), and displayed higher rates of other CVRFs (p <0.001 for each). A personal history of CVD was reported in 18.8% of women with PAD and in 6.1% of those without PAD (p <0.001). At multivariate regression analysis, PAD (odds ratio [OR]: 2.15; 95% confidence interval [CI]: 1.33-3.47), and hypertension (OR: 2.20; 95%CI: 1.24-3.88) were the strongest factors associated with CVD presence.
    Conclusions: PAD is a strong marker of CVD in this selected series of postmenopausal women. If confirmed in the general population, PAD screening through ABI calculation may be considered for CV risk assessment in postmenopausal women.

    Abstract Background: Immune checkpoint inhibitors (ICI) have revolutionized the management of many cancer types by drastically improving the median survival rate of patients. However, this efficiency comes at the cost of a high rate of immune-related adverse events, including lethal cardiac manifestations. Rapidly fatal cases of ICI-induced myocarditis have been reported and drawn considerable attention over the past years. However, it is essential to bear in mind that not all cardiac events occurring under ICI therapy are necessarily myocarditis.
    Case summary: A 61-year-old female treated with pembrolizumab for a stage IV melanoma was admitted for chest pain leading to the diagnosis of ICI-related myocarditis based on the description of a discrete left ventricular subepicardial late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) imaging. ICI were suspended and intravenous methylprednisolone initiated. A second line anti-MEK therapy was initiated. After a month of treatment, similar chest pain occurred. CMR revealed a midventricular stress cardiomyopathy and no LGE was detected.
    Discussion: Not all cardiac manifestations occurring under ICI therapy are drug-related adverse events, therefore differential diagnoses must systematically be considered as the contraindication of ICI may have a major impact on patient prognosis. Cardiac imaging should be performed early and plays a key role in the management strategy.

    Abstract New diagnostic techniques have now become available that will enable us to obtain information on coronary artery disease (CAD), which was not previously possible. This is urgently needed, since changes in CAD management are highly desirable considering that up to 60% of patients die due to an insufficient diagnostic strategy (reactive strategy). In this article, the pathophysiology of CAD and the evidence of current concepts on coronary atherosclerosis are critically reviewed. Consequently, a shift from a 'reactive strategy' of CAD management to an active strategy is proposed in order to detect and treat patients before acute myocardial infarcts occur. Reliability, repeatability, cost-effectiveness and comfort are important features of an optimal test for this active strategy. This perspective gives an overview of current and future tests with respect to these features. The novel tomographic techniques are particularly promising with respect to standardization and reproducibility, which will set the basis for the determination of test performance and, consequently, cost-effectiveness. Assessment of cost-effectiveness is increasingly important, since prevalence of CAD is high and will most likely increase, while resources will remain restricted in most countries. Considering these economic restrictions, this article also proposes new mathematical tools using data from prospective trials and large international registries as an objective means to select the best tests for CAD diagnosis and management, and to identify those patient subsets which benefit most from an active strategy.

    Abstract Objectives: The identification of patients with mitral valve prolapse (MVP) presenting high arrhythmic risk remains challenging. Cardiovascular Magnetic Resonance (CMR) feature tracking (FT) may improve risk stratification. We analyzed the role of CMR-FT parameters in relation to the incidence of complex ventricular arrhythmias (cVA) in patients with MVP and mitral annular disjunction (MAD).
    Methods: 42 patients with MVP and MAD who underwent 1.5 T CMR were classified as MAD-cVA (n = 23, 55%) in case of cVA diagnosed on a 24-h Holter monitoring and as MAD-noVA in the absence of cVA (n = 19, 45%). MAD length, late gadolinium enhancement (LGE), basal segments myocardial extracellular volume (ECV) and CMR-FT were assessed.
    Results: LGE was more frequent in the MAD-cVA group in comparison with the MAD-noVA group (78% vs 42%, p = 0.002) while no difference was observed in terms of basal ECV. Global longitudinal strain (GLS) was reduced in MAD-cVA compared to MAD-noVA (- 18.2% ± 4.6% vs - 25.1% ± 3.1%, p = 0.004) as well as global circumferential strain (GCS) at the mid-ventricular level (- 17.5% ± 4.7% vs - 21.6% ± 3.1%, p = 0.041). Univariate analysis identified as predictors of the incidence of cVA: GCS, circumferential strain (CS) in the basal and mid infero-lateral wall, GLS, regional longitudinal strain (LS) in the basal and mid-ventricular inferolateral wall. Reduced GLS [Odd ratio (OR):1.56 (confidence interval (CI) 95%: 1.45-2.47; p < 0.001)] and regional LS in the basal inferolateral wall [OR: 1.62 (CI 95%: 1.22-2.13; p < 0.001)] remained independent prognostic factors in multivariate analysis.
    Conclusion: In patients with MVP and MAD, CMR-FT parameters are correlated with the incidence of cVA and may be of interest in arrhythmic risk stratification.

    Abstract Background: Cardiovascular magnetic resonance (CMR) is considered the method of choice for evaluation of aortic root dilatation in congenital heart disease. Usually, a cross-sectional 2D cine stack is acquired perpendicular to the vessel's axis. However, this method requires a considerable patient collaboration and precise planning of image planes. The present study compares a recently introduced 3D self-navigated free-breathing high-resolution whole heart CMR sequence (3D self nav) allowing a multiplanar retrospective reconstruction of the aortic root as an alternative to the 2D cine technique for determination of aortic root diameters.
    Methods: A total of 6 cusp-commissure (CuCo) and cusp-cusp (CuCu) enddiastolic diameters were measured by two observers on 2D cine and 3D self nav cross-sectional planes of the aortic root acquired on a 1.5 T CMR scanner. Asymmetry of the aortic root was evaluated by the ratio of the minimal to the maximum 3D self nav CuCu diameter. CuCu diameters were compared to standard transthoracic echocardiographic (TTE) aortic root diameters.
    Results: Sixty-five exams in 58 patients (32 ± 15 years) were included. Typically, 2D cine and 3D self nav spatial resolution was 1.1-1.5
    Conclusion: Both, the 3D self nav and 2D cine CMR techniques allow reliable determination of aortic root diameters. However, we propose to privilege the 3D self nav technique and measurement of CuCu diameters to avoid underestimation of the maximum diameter, particularly in patients with asymmetric aortic roots and/or BAV.

    Abstract Long-lasting symptoms after SARS-CoV-2 infection have been described many times in the literature and are referred to as Long COVID. In this prospective, longitudinal, monocentric, observational study, we collected the health complaints of 474 patients (252 ambulatory and 222 hospitalized) at Lausanne University Hospital 1 year after COVID-19 diagnosis. Using a self-reported health survey, we explored cardiopulmonary, vascular, neurological, and psychological complaints. Our results show that age, Charlson comorbidity index, and smoking habits were associated with hospital admission. Regarding the vascular system, we found that having had thromboembolism before SARS-CoV-2 infection was significantly associated with a higher risk of recurrence of thromboembolism at 1 year. In the neurologic evaluation, the most frequent symptom was fatigue, which was observed in 87.5% of patients, followed by "feeling slowed down", headache, and smell disturbance in 71.5%, 68.5%, and 60.7% of cases, respectively. Finally, our cohort subjects scored higher overall in the STAI, CESD, Maastricht, and PSQI scores (which measure anxiety, depression, fatigue, and sleep, respectively) than the healthy population. Using cluster analysis, we identified two phenotypes of patients prone to developing Long COVID. At baseline, CCS score, prior chronic disease, stroke, and atrial fibrillation were associated with Long COVID. During COVID infection, mechanical ventilation and five neurological complaints were also associated with Long COVID. In conclusion, this study confirms the wide range of symptoms developed after COVID with the involvement of all the major systems. Early identification of risk factors associated with the development of Long COVID could improve patient follow-up; nevertheless, the low specificity of these factors remains a challenge to building a systematic approach.

    Abstract Background: Implantable cardioverter defibrillator (ICD) represents the most valuable sudden cardiac death (SCD) prophylactic strategy in patients with heart failure and severely reduced left ventricular ejection fraction (LVEF). To date, it is still unknown how to integrate the information given by cardiac magnetic resonance (CMR) into clinical and transthoracic echocardiography (TTE) work-up of non-ischemic cardiomyopathy (NICM) and ischemic cardiomyopathy (ICM) patients for accurate risk stratification.
    Methods and results: DERIVATE is a prospective, international, multicenter, observational registry of NICM and ICM patients with chronic heart failure and reduced LVEF who will undergo clinical evaluation, TTE and CMR. The registry will enrol cohorts from 34 sites. Complete risk factor, clinical presentation, TTE and CMR data will be collected and each patient will be followed-up for outcomes. Primary end point of the study is all-cause mortality. Secondary end points are: cardiovascular death, SCD, aborted SCD, sustained ventricular tachycardia (VT), and major adverse cardiac events (MACE) defined as a composite endpoint of SCD, aborted SCD, and sustained VT. Specifically, we will determine CMR findings that predict outcomes, with incremental value over LVEF and NYHA classification. Secondary aims consist in providing a comprehensive clinical and imaging score and testing the contribution of machine learning to determine prognostic CMR parameters.
    Conclusions: The final objective of the study consists in the identification of prognostic CMR parameters in a large prospective cohort for a better selection of patients with heart failure being worthy of primary prevention ICD therapy. (clinicaltrials.gov registration: RTT# NCT03352648).

    Abstract The year of 2022 was marked by many novelties in the fields of interventional cardiology, heart failure, electrophysiology, cardiac imaging, and congenital heart disease. These advances will certainly change our daily practice, on top of improving the diagnosis and treatment of many heart conditions. In addition, the European Society of Cardiology has updated its guidelines on pulmonary hypertension, ventricular arrhythmias and sudden death, cardiovascular assessment of patients undergoing non-cardiac surgery. The members of the Cardiology division of Lausanne University Hospital (CHUV) here present the publications which they considered to be the most important of the past year.
