The Delphi method was used to build the present consensus. This expert panel consensus includes recommendations for indications, the procedure (with patient preparation), stress-inducing drugs, the acquisition protocol, interpretation and risk stratification by stress magnetic resonance imaging.

Extracorporeal membrane oxygenation network organisation and clinical outcomes during the COVID-19 pandemic in Greater Paris, France: a multicentre cohort study.

Background: In the Île-de-France region (henceforth termed Greater Paris), extracorporeal membrane oxygenation (ECMO) for severe acute respiratory distress syndrome (ARDS) was considered early in the COVID-19 pandemic. We report ECMO network organisation and outcomes during the first wave of the pandemic.

Methods: In this multicentre cohort study, we present an analysis of all adult patients with laboratory-confirmed SARS-CoV-2 infection and severe ARDS requiring ECMO who were admitted to 17 Greater Paris intensive care units between March 8 and June 3, 2020.

Advanced measurements of coronary calcium scores: how does it affect current clinical practice?

Coronary artery calcium (CAC) scoring has emerged as a marker of the burden of atheromatous disease and has been included in scoring systems. The practice of myocardial revascularization, considering percutaneous procedures or surgical strategies, is dramatically changing over years and the prognostic significance of CAC scoring is gradually being conceived. In this interdisciplinary scenario, vessel specific calcium scoring, mapping of coronary calcification and its integration with functional assessment of coronary artery disease might change the future decisions in the catheterization lab and operative theaters.

Perioperative management after elective cardiac surgery: the predictive value of procalcitonin for infective and noninfective complications.

Procalcitonin (PCT) has been associated with adverse outcomes after cardiac surgery. Nevertheless, there is no consensus on thresholds and timing of PCT measurement to predict adverse outcomes. A total of 960 patients undergoing elective cardiac surgery were retrospectively evaluated.

Polymers and Nanoparticles for Statin Delivery: Current Use and Future Perspectives in Cardiovascular Disease.

Atherosclerosis-related coronary artery disease (CAD) is one of the leading sources of mortality and morbidity in the world. Primary and secondary prevention appear crucial to reduce CAD-related complications. In this scenario, statin treatment was shown to be clinically effective in the reduction of adverse events, but systemic administration provides suboptimal results.

Case report: takotsubo cardiomyopathy after transcatheter aortic valve-in-valve replacement.

Background: Transcatheter aortic valve implantation (TAVI) has become a first-line therapeutic option in patients with severe, symptomatic aortic stenosis at increased surgical risk. Despite its success, the TAVI procedure has been associated with acute life-threatening complications as myocardial infarction secondary to periprocedural coronary occlusion, annular rupture, or vascular injury.

Case Summary: A 79-year-old woman with a dysfunctional bioprosthetic valve following previous surgical valve replacement was hospitalized in our institution to perform a Valve-in-Valve Transcatheter Aortic Valve Replacement (ViV TAVR).

Arteriovenous fistulas thrombosis in hemodialysis patients with COVID-19.

Background: The current Coronavirus disease 2019 (COVID-19) outbreak is associated with significant mortality, especially in patients suffering from end stage renal disease (ESRD) and hemodialysis patients. Several previous studies reported an over-risk of arterial and venous thrombosis, in particular pulmonary embolism and venous thrombosis of catheter in COVID19 patients in intensive care unit. However, arteriovenous fistula (AVF) thrombosis has rarely been reported yet in these patients.

Diagnosis and Treatment of Iron Deficiency in Heart Failure: OFICSel study by the French Heart Failure Working Group.

Aims: Iron deficiency (ID) occurs in about 50% of patients with heart failure (HF). The European Society of Cardiology (ESC) recommends ID diagnostic testing in newly diagnosed patients with HF and during follow-up, with intravenous iron supplementation (IS) only recommended in patients with HF with reduced ejection fraction (HFrEF). This study aimed to assess prevalence, clinical characteristics, and application of ESC guidelines for ID and IS in patients with HF in the real-life clinical setting.

Brain Glucose Metabolism in Cerebral Amyloid Angiopathy: An FDG-PET Study.

Background And Purpose: The in vivo diagnosis of cerebral amyloid angiopathy (CAA) is currently based on the Boston criteria, which largely rely on hemorrhagic features on brain magnetic resonance imaging. Adding to these criteria F-fluoro-deoxy-D-glucose (FDG) positron emission tomography, a widely available imaging modality, might improve their accuracy. Here we tested the hypothesis that FDG uptake is reduced in posterior cortical areas, particularly the primary occipital cortex, which pathologically bear the brunt of vascular Aβ deposition.

The Use of Bioactive Polymers for Intervention and Tissue Engineering: The New Frontier for Cardiovascular Therapy.

Coronary heart disease remains one of the leading causes of death in most countries. Healthcare improvements have seen a shift in the presentation of disease with a reducing number of ST-segment elevation myocardial infarctions (STEMIs), largely due to earlier reperfusion strategies such as percutaneous coronary intervention (PCI). Stents have revolutionized the care of these patients, but the long-term effects of these devices have been brought to the fore.

Impact of ablation index settings on pulmonary vein reconnection.

Purpose: Ablation index (AI) is a radiofrequency lesion quality marker. The AI value that allows effective and safe pulmonary vein isolation (PVI) is still debated. We evaluated the incidence of acute and late PV reconnection (PVR) with different AI settings and its predictors.

Effect of Statins on Platelet Activation and Function: From Molecular Pathways to Clinical Effects.

Purpose: Statins are a class of drugs widely used in clinical practice for their lipid-lowering and pleiotropic effects. In recent years, a correlation between statins and platelet function has been unveiled in the literature that might introduce new therapeutic indications for this class of drugs. This review is aimed at summarizing the mechanisms underlying statin-platelet interaction in the cardiologic scenario and building the basis for future in-depth studies.

The Impact of Patients With Cardiac Amyloidosis in HFpEF Trials.

Heart failure with preserved ejection fraction (HFpEF) is an increasingly diagnosed condition whose failure to respond to new drugs effective in heart failure with reduced ejection fraction is of great concern. HFpEF is an incompletely understood and markedly heterogeneous syndrome, but cardiac amyloidosis is increasingly recognized as one of its various causes. The specific hemodynamic and pathophysiological features of cardiac amyloidosis result in poor tolerance of heart failure medications and in worse outcomes compared with other causes.

Focus on stereotactic radiotherapy: A new way to treat severe ventricular arrhythmias?

Ventricular tachycardia has a significant recurrence rate after ablation for several reasons, including inaccessible substrate. A non-invasive technique to ablate any defined areas of myocardium involved in arrhythmogenesis would be a potentially important therapeutic improvement if shown to be safe and effective. Early feasibility studies of single-fraction stereotactic body radiotherapy have demonstrated encouraging results, but rigorous evaluation and follow-up are required.

[ F]FDG PET may differentiate cerebral amyloid angiopathy from Alzheimer's disease.

Background: Cerebral amyloid angiopathy (CAA) is a frequent cause of both intracerebral hemorrhage (ICH) and cognitive impairment in the elderly. Diagnosis relies on the Boston criteria, which use magnetic resonance imaging markers including ≥2 exclusively lobar cerebral microbleeds (lCMBs). Although amyloid positron emission tomography (PET) may provide molecular diagnosis, its specificity relative to Alzheimer's disease (AD) is limited due to the prevalence of positive amyloid PET in cognitively normal elderly.

Redo aortic valve replacement for prosthesis endocarditis in patients previously classified as high or prohibitive risk: a narrative review.

Transcatheter aortic valve implantation (TAVI) and sutureless aortic valve replacement (Su-AVR) enabled in the last years many patients at high or prohibitive risk to be treated for their severe symptomatic aortic valve stenosis. As often happens in medicine, new techniques bring not only new hopes, but also new problems. In recent years, alongside the lengthening of the life of these patients treated with TAVI or Su-AVR, cardiologists and cardiac surgeons have had to face the long-term complications associated with the implantation of these devices, such as the prosthetic infective endocarditis.

The quest for the optimal surgical management of tricuspid valve endocarditis in the current era: a narrative review.

Tricuspid valve endocarditis (TVE) is a growing concern with increasing rates and mortality burden. The currently changing etiology, the antibiotic resistance and the raise in iatrogenic causes as with implantable cardiac devices [cardiac implantable electronic device (CIED)], represent a challenge for the management of these patients. The progressively widespread use of CIEDs is adding to the more commonly known intravenous (IV) drug abuse in the list of causes.

A management framework for left sided endocarditis: a narrative review.

Left sided endocarditis (LSE) can include the entirety or portion of mitral and/or aortic valve and the structures in their anatomical contiguity and represent a significant portion of emergency surgical activity. Literature and guidelines on the management of LSE relies mainly on observational studies given the difficulty in designing randomized trials in emergency settings. Heart teams (HT) are often called in to difficult decisions on the most appropriate strategy to adopted in case of LSE.
