Background: Achieving hemostasis of large bore venous access sites can be challenging and time consuming. Closure devices have proven to be superior in achieving hemostasis, reducing time to ambulation and improving patient comfort, compared to manual hemostasis techniques after femoral venous and arterial access. The closure of the jugular vein following large bore access has not been investigated in previous studies.

Background And Hypothesis: Kidney macrophage infiltration is a histological hallmark of vasculitic lesions and is strongly linked to disease activity in anti-neutrophil cytoplasmic antibodies (ANCA)-associated glomerulonephritis (AGN). The precise mechanisms by which kidney macrophages influence local inflammation and long-term damage remain largely unknown.

Methods: Here, we investigate kidney macrophage diversity using single-cell transcriptome analysis of 25 485 freshly retrieved unfrozen, high-quality kidney CD45+ immune cells from five AGN patients during active disease, a lupus nephritis and nephrectomy control.

Background: Pulmonary embolism is an important cause of preventable mortality. Treatment strategies depend on risk stratification. High-risk patients, and some intermediate-high-risk patients, require urgent reperfusion therapy.

Background: Radiofrequency catheter ablation in the left ventricular summit region is a challenging procedure due to proximity to the coronary arteries. Pulsed field ablation, a novel non-thermal ablation modality, does not cause damage to coronary arteries and may be used in the left ventricular summit region.

Case Summary: We describe a 45-year-old symptomatic patient with epicardial left ventricular summit premature ventricular complexes.

Background And Aims: Anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitides (AAV) is associated with an increased cardiovascular risk, particularly the myeloperoxidase AAV serotype (MPO-AAV). Distinct alterations in monocyte phenotypes may cause accelerated atherosclerotic disease in AAV.

Methods: A cohort including 43 AAV patients and 19 healthy controls was included for downstream analyses.
