Objectives: This study aimed to evaluate the incidence, clinical impact, and predictors of late ventricular arrhythmias (VAs) in left ventricular assist device (LVAD) recipients aiming to clarify implantable cardioverter-defibrillator (ICD) indications.
Background: The arrhythmic risk and need for ICD in patients implanted with an LVAD are not very well known.
Methods: This observational study was conducted in 19 centers between 2006 and 2016. Late VAs were defined as sustained ventricular tachycardia or fibrillation occurring >30 days post-LVAD implantation, without acute reversible cause and requiring appropriate ICD therapy, external electrical shock, or medical therapy.
Results: Among 659 LVAD recipients, 494 (median 58.9 years of age; mean left ventricular ejection fraction 20.7 ± 7.4%; 73.1% HeartMate II, 18.6% HeartWare, 8.3% Jarvik 2000) were discharged alive from hospital and included in the final analysis. Late VAs occurred in 133 (26.9%) patients. Multivariable analysis identified 6 independent predictors of late VAs: VAs before LVAD implantation, atrial fibrillation before LVAD implantation, idiopathic etiology of the cardiomyopathy, heart failure duration >12 months, early VAs (<30 days post-LVAD), and no angiotensin-converting enzyme inhibitors during follow-up. The "VT-LVAD score" was created, identifying 4 risk groups: low (score 0 to 1), intermediate (score 2 to 4), high (score 5 to 6), and very high (score 7 to 10). The rates of VAs at 1 year were 0.0%, 8.0%, 31.0% and 55.0%, respectively.
Conclusions: Late VAs are common after LVAD implantation. The VT-LVAD score may help to identify patients at risk of late VAs and guide ICD indications in previously nonimplanted patients.

Introduction: Cardiac amyloidosis is an underdiagnosed disease, and its prevalence is probably higher than previously estimated. We aimed to investigate the effect of introducing a systemic diagnostic algorithm for cardiac amyloidosis in clinical practice.
Methods: A systematic diagnostic algorithm was developed and clinically applied in two hospitals in Eastern Denmark.

Background: Mitral regurgitation (MR) may rarely worsen after transcatheter aortic valve implantation (TAVI) due to mechanical interference from the transcatheter heart valve (THV). Standard surgical approaches in these cases are often challenging due to anatomical constraints. Thus, there is a need for the development of effective alternatives to address this issue.

Background: The incidence of cancer therapy-related cardiac dysfunction is increasing with the growing number of breast cancer patients. In particular, patients with active cancer combined with severe irreversible cardiac dysfunction present significant challenges in treatment decision-making.
Case Summary: A 40-year-old woman with Stage II HER-2-positive breast cancer received anthracycline followed by HER2-targeted agents.

Hypertension is a pervasive and progressive complication in chronic kidney disease (CKD) patients, affecting up to 90% of those in advanced stages or on dialysis. A particularly insidious aspect of this condition is nocturnal hypertension, characterized by high blood pressure (BP) during sleep and a blunted or absent nighttime BP dipping-phenomena associated with accelerated CKD progression and increased cardiovascular risk. Despite its strong prognostic significance, nocturnal hypertension remains underdiagnosed due to limited use of ambulatory BP monitoring.

Objective: This study evaluates cardiac function in older adults with T2DM and preserved LVEF using two-dimensional speckle-tracking echocardiography to explore the risk factors associated with subclinical left ventricular systolic dysfunction (GLS <18%) in this population.
Methods: All patients (n = 87, aged 60 years and above) and controls (n = 20) underwent clinical assessment and echocardiography, including GLS assessment.
Results: Univariate analysis identified gender (OR 3.
