Cardiopulmonary bypass, along with heparinization and hemodilution, is thought to affect all pathways of the hemostatic process, leading to excessive bleeding and worsened morbidity and mortality. The traditionally used standard laboratory tests (SLTs) were not designed for the surgical setting, have long turnaround times, and are poor predictors of bleeding. This review aims to give an overview of viscoelastic assays (VEAs), compare VEAs to conventional testing methods, and summarize the evidence for VEAs in cardiac surgery. A search of Medline via Pubmed, Scopus, and Embase yielded 2,868 papers, which we reviewed and summarized the key findings. VEAs such as rotational thromboelastometry and thromboelastography provide a quick turnaround, graphical, global impression of hemostasis in whole blood. VEAs allow for the analysis of specific contributors to the coagulation process and may facilitate cause-oriented hemostatic treatment and the development of treatment algorithms. VEAs have been found to have a high specificity and high negative predictive value for coagulopathic bleeding. Patients treated with VEA-based algorithms have been shown to have lower rates of bleeding, transfusion requirements, and exposure to allogeneic blood products. However, VEA-based algorithms have not demonstrated a mortality benefit and evidence for outcomes such as surgical re-exploration and hospital length of stay remains equivocal. In conclusion, VEAs have been shown to be comparable if not superior to SLTs in cardiac surgery. Further large-scale studies are needed to better evaluate the impact of VEAs on clinical outcomes.</p>","PeriodicalId":21673,"journal":{"name":"Seminars in thrombosis and hemostasis","volume":" ","pages":"417-429"},"PeriodicalIF":4.1,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143410312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obstetric APS (OAPS) is associated with pregnancy morbidity, including early recurrent pregnancy loss (RPL), preeclampsia, premature birth and stillbirth. Treatment regimens for women with OAPS are designed to optimise pregnancy outcomes. It is still debated which intervention results in the most optimal pregnancy outcome. This scoping review examines treatment options for women with OAPS presenting with RPL based solely on randomized controlled trials (RCTs) reporting pregnancy outcomes. A systematic search identified 1,234 studies published up to January 2026, from which 14 RCTs met the inclusion criteria: pregnant women with APS defined as persistent aPL positivity and RPL (≥2) receiving therapeutic intervention with live birth as the primary outcome. These RCTs, published between 1992 and 2017, included 1,878 participants. Secondary outcomes, including birth weight, preeclampsia, preterm delivery, and bleeding were also analyzed. Different treatment options such as low-dose aspirin (LDA), unfractionated heparin, low molecular weight heparin (LMWH), corticosteroids and intravenous immunoglobulin were used in the clinical trials. Antithrombotic therapy (LDA+LMWH) was associated with higher live birth rates compared with the other evaluated strategies. However, this finding is based on a small number of heterogeneous RCTs and is disproportionately driven by a single large trial. Consequently, substantial uncertainty remains. High-quality, adequately powered RCTs are urgently needed to provide robust evidence for optimal OAPS management.</p>","PeriodicalId":21673,"journal":{"name":"Seminars in thrombosis and hemostasis","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147842565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This narrative review synthesizes evidence on LLBFR's hemodynamic and endothelial effects, highlighting pressure-dependent basal lamina thickening, impaired flow-mediated dilation, and transient elevations in peripheral venous pressure (PVP). It emphasizes the importance of pre-exercise risk stratification, genetic screening for factor V Leiden and prothrombin mutations, and assessment of cardiovascular and coagulation markers. For athletes with confirmed DVT, PTS, or multiple risk factors, LLBFR should be contraindicated. In Paralympic athletes with spinal cord injury, stringent exclusion criteria (e.g., severe autonomic dysreflexia, pressure ulcers) are essential, while female athletes may require individualized monitoring of coagulation changes during oral contraceptive use and pregnancy. Although LLBFR shows promise for preserving muscle function when traditional loading is impractical, robust, large-scale studies measuring thrombogenesis and fibrinolysis markers are urgently needed.

Diagnosis is challenging and requires integrating bleeding history, VWF antigen and activity measurements, FVIII assays, and specialized phenotyping. Genetic testing is increasingly recognized as a key component. Here, we review current concepts in VWD diagnostics and highlight the Spanish Clinical and Molecular Profile of von Willebrand Disease (PCM-EVW-ES) project as a model for genomics-enabled precision medicine. PCM-EVW-ES is a multicenter initiative involving 48 hospitals, centralized phenotypic testing, and next-generation sequencing of the <i>VWF</i> coding region, enabling definitive classification in 730 individuals with VWD to date. Harmonized recruitment criteria and standardized workflows improve subtype assignment, uncover complex genotypes, refine genotype-phenotype correlations, and facilitate the identification of asymptomatic carriers. The PCM-EVW-ES variant spectrum highlights recurrent disease-causing variants in Spain and underscores the value of coordinated national registries for variant curation. Building on these data, we propose a diagnostic algorithm in which bleeding assessment and first-line VWF/FVIII assays, combined with, early <i>VWF</i> molecular testing increases diagnostic accuracy and guides targeted second-line investigations to confirm and refine VWD subtype classification. We also outline persisting challenges, including the interpretation of variants of uncertain significance and patients without identifiable pathogenic <i>VWF</i> variants, and future directions integrating third-generation sequencing, expanded gene panels, functional studies, and artificial-intelligence-driven multiomic approaches.
