Tricuspid regurgitation after heart transplantation: where innovation and intervention are in hibernation.

Tricuspid regurgitation (TR) is a common valvular dysfunction following heart transplantation (HT), with reported prevalence rates ranging from 19 to 84%, primarily depending on the duration of follow-up. Its etiology is multifactorial and includes surgical technique, ischemic time, primary graft dysfunction, pulmonary hypertension, pacemaker leads, and endomyocardial biopsies. Severe TR can significantly impair graft function, exercise capacity, and patient survival.

Coexistence of cardiac sarcoidosis and arrhythmogenic cardiomyopathy-associated genetic variants: a multicentre case-control study.

Background: Cardiac sarcoidosis (CS) is a chronic inflammatory disease characterised by non-caseating granulomas, while arrhythmogenic cardiomyopathy (ACM) is a genetic condition mainly affecting desmosomal proteins. The coexistence of CS and genetic variants associated with ACM is not well understood, creating challenges in diagnosis and management. This study aimed to describe the clinical, imaging and genetic features of patients with both conditions.

In the Twilight of Evidence: Is Bypass Surgery Still on the Table for Cardiac Allograft Vasculopathy?

Cardiac allograft vasculopathy (CAV) is a major prognosis-limiting factor in patients undergoing orthotopic heart transplantation (HT). Due to the diffuse involvement of the coronary tree, CAV lesions are often not amenable to percutaneous coronary intervention (PCI), leaving coronary artery bypass grafting (CABG) and retransplantation as primary revascularization options. : The latest guidelines from the International Society for Heart and Lung Transplantation (ISHLT) recognize CABG as a viable option but with a downgraded strength of recommendation.

Retinal microvascular dysfunction in systemic sclerosis.

Background And Aims: Systemic sclerosis (SSc) is a systemic autoimmune disease, characterized by widespread microvasculopathy and fibrosis. Vascular and endothelial cell changes appear to precede other features of SSc. Retinal vascular analysis is a new, easy-to-use tool for the assessment of retinal microvascular function.

Vascular Endothelial Effects of Sacubitril/Valsartan in Heart Failure With Reduced Ejection Fraction: Randomized Controlled Trial.

Background: The mechanism of how sacubitril/valsartan improves outcomes in heart failure with reduced ejection fraction (HFrEF) is still incompletely understood.

Objectives: The aim of this trial was to delineate the effects of sacubitril/valsartan on endothelial function, retinal microvascular function, and arterial stiffness in HFrEF.

Methods: This double-blind controlled trial randomized 79 stable HFrEF patients with NYHA class II-IV on guideline-recommended therapy (mean age: 59.

Sodium-glucose co-transporter 2 inhibitors in left ventricular assist device and heart transplant recipients: a mini-review.

In recent years, sodium-glucose co-transporter 2 inhibitors (SGLT2i) emerged as promising therapeutic agents in managing heart failure (HF). They demonstrated a significant impact on reducing HF hospitalizations and related mortality in patients with reduced and preserved ejection fraction. However, evidence supporting their use in patients with left ventricular assist device (LVAD) and heart transplant (HT) recipients is still limited.

Lateral QRS amplitude is independently associated with outcome after cardiac resynchronization therapy: Advancing patient selection?

Background: Cardiac resynchronization therapy (CRT) is a cornerstone in the treatment of selected heart failure patients. However, a relevant proportion of patients do not show beneficial response. Identification of simple, additive, and outcome-relevant selection criteria may improve selection of patients.

Prognostic value of plasma big endothelin-1 in patients with light chain cardiac amyloidosis.

Background: Light chain cardiac amyloidosis (AL-CA) is associated with a high incidence of mortality. Big endothelin-1 (ET-1), the precursor of endothelial-vasoconstrictive ET-1, is closely related to the concentration of bioactive ET-1. Association between big ET-1 and prognosis of AL-CA has not yet been documented.

Three years follow-up of Venetoclax in advanced-stage, relapsed or refractory AL amyloidosis with cardiac involvement and t(11;14) with BCL2 expression.

Further line treatment of patients with advanced stage AL amyloidosis with cardiac involvement is challenging. Venetoclax is a promising option, especially in t(11;14) and BCL2 expression.In our multicentre observational study, we report the 3-year follow-up of Venetoclax treatment in 9 patients with advanced, relapsed or refractory AL amyloidosis with t(11;14) and BCL-2 expression in > 50% of plasma cells.

Historic characteristics and mortality of patients in the Swiss Amyloidosis Registry.

Aims Of The Study: Systemic amyloidoses are rare protein-folding diseases with heterogeneous, often nonspecific clinical presentations. To better understand systemic amyloidoses and to apply state-of-the-art diagnostic pathways and treatment, the interdisciplinary Amyloidosis Network was founded in 2013 at University Hospital Zurich. In this respect, a registry was implemented to study the characteristics and life expectancy of patients with amyloidosis within the area covered by the network.

Medication adherence in adults after hospitalization for heart failure: A cross-sectional study.

Background: Medication non-adherence in heart failure (HF) leads to increased mortality, morbidity and healthcare costs. However, no study has investigated HF patients' post-hospitalization medication non-adherence in Switzerland.

Objectives: Our primary aim was to assess the prevalence of post-discharge medication non-adherence in patients with HF.

Impaired retinal micro-vascular function in patients with atrial fibrillation.

Background: Cardiovascular (CV) risk factors and CV diseases, in particular heart failure, are strongly associated with impaired microvascular retinal endothelial function. Whether atrial fibrillation (AF) contributes to vascular dysfunction is not clear. Therefore, the aim of this study was to investigate the impact of AF on retinal microvascular function.

Safety of continuing mineralocorticoid receptor antagonist treatment in patients with heart failure with reduced ejection fraction and severe kidney disease: Data from Swedish Heart Failure Registry.

Aims: Mineralocorticoid receptor antagonists (MRAs) improve outcomes in heart failure with reduced ejection fraction (HFrEF) but remain underused and are often discontinued especially in patients with chronic kidney disease (CKD) due to concerns on renal safety. Therefore, in a real-world HFrEF population we investigated the safety of MRA use, in terms of risk of renal events, any mortality and any hospitalization, across the estimated glomerular filtration rate (eGFR) spectrum including severe CKD.

Methods And Results: We analysed patients with HFrEF (ejection fraction <40%), not on dialysis, from the Swedish Heart Failure Registry.

Diverging role of epicardial adipose tissue across the entire heart failure spectrum.

Aims: Epicardial adipose tissue (EAT) is a metabolically highly active tissue modulating numerous pathophysiological processes. The aim of this study was to investigate the association between EAT thickness and endothelial function in patients with heart failure (HF) across the entire ejection fraction spectrum.

Methods And Results: A total of 258 patients with HF with an ejection fraction across the entire spectrum [HF with reduced ejection fraction (HFrEF), n = 168, age 60.

Arrhythmic Manifestations of Cardiac Amyloidosis: Challenges in Risk Stratification and Clinical Management.

Amyloidosis is a systemic disease characterized by extracellular deposits of insoluble amyloid in various tissues and organs. Cardiac amyloidosis is a frequent feature of the disease, causing a progressive, restrictive type of cardiomyopathy, and is associated with adverse clinical outcomes and increased mortality. The typical clinical presentation in patients with cardiac amyloidosis is heart failure (HF) with preserved ejection fraction.

Trends in voice characteristics in patients with heart failure (VENTURE) in Switzerland: Protocol for a longitudinal observational pilot study.

Introduction: Heart Failure (HF) is a major health and economic issue worldwide. HF-related expenses are largely driven by hospital admissions and re-admissions, many of which are potentially preventable. Current self-management programs, however, have failed to reduce hospital admissions.

Long-distance donor heart procurement using an innovative cold static storage system.

The global lack of donor shortage poses a major limitation for heart transplantation. New concepts with expanded donor inclusion criteria comprise extended transport distances and prolonged ischemic times with the aim of reaching a larger number of potential donors. Recent developments in cold storage solutions may allow more donor hearts with prolonged ischemic times to be use for transplantation in the future.
