Diagnosing myocarditis is still challenging due to its varying presentation ranging from none or mild symptoms to sudden cardiac death. Clinical presentation, electrocardiography, and cardiac biomarkers seem not to be sufficient for a reliable diagnosis. In fact, an unequivocal myocardial characterization is needed, applying endomyocardial biopsy (EMB) and cardiac magnetic resonance (CMR), a technique which demonstrates high accuracy to histology. Besides the assessment of functional parameters ...
Inherited platelet disorders (IPDs) are a group of rare conditions featured by reduced circulating platelets and/or impaired platelet function causing variable bleeding tendency. Additional hematological or non hematological features, which can be congenital or acquired, distinctively mark the clinical picture of a subgroup of patients. Recognizing an IPD is challenging, and diagnostic delay or mistakes are frequent. Despite the increasing availability of next-generation sequencing, a careful ph...
COVID-19 bezeichnet eine der schlimmsten Krisen unserer Generation und stellt (nicht nur) fur das Gesundheitssystem eine schwer bewaltigbare Herausforderung dar. Mortalitat und Morbiditat sind im Vergleich zu anderen saisonalen Erkrankungen wie der Influenza deutlich erhoht. COVID-19 bedroht allerdings nicht die gesamte Bevolkerung in gleichem Mase. Hochrisikopatienten sind alter und leiden an kardiovaskularen Erkrankungen wie Bluthochdruck, Diabetes mellitus oder einer koronaren Herzerkrankung....

Acquired hemophilia A (AHA) is caused by autoantibodies neutralizing coagulation factor VIII (FVIII). In the presence of inhibitors against FVIII, acute bleeds can be managed with bypassing agents, including recombinant factor VIIa (eptacog alfa activated, NovoSeven) and activated prothrombin complex concentrate (FEIBA), as well as recombinant porcine FVIII (susoctocog alfa, Obizur). Studies comparing these agents directly are not available, and indirect evidence suggests an overall similar effi...
Ovarian vein thrombosis (OVT) is a rare type of venous thromboembolism. The most common risk factors for OVT include pregnancy, oral contraceptives, malignancies, recent surgery, and pelvic infections; however, in 4 to 16% of cases, it can be classified as idiopathic. Most of the available information regards pregnancy-related OVT, which has been reported to complicate 0.01 to 0.18% of pregnancies and to peak around 2 to 6 days after delivery or miscarriage/abortion. The right ovarian vein is mo...
Immune thrombocytopenia (ITP) is an autoimmune disease that is characterized by a significant reduction in the number of circulating platelets and frequently associated with bleeding. Although the pathogenesis of ITP is still not completely elucidated, it is largely recognized that the low platelet count observed in ITP patients is due to multiple alterations of the immune system leading to increased platelet destruction as well as impaired thrombopoiesis. The clinical manifestations and patient...
Hemorrhage after trauma remains a significant cause of preventable death. Trauma-induced coagulopathy (TIC) at the time of hospital admission is associated with an impaired outcome. Rather than a universal phenotype, TIC represents a complex hemostatic disorder, and standard coagulation tests are not designed to adequately reflect the complexity of TIC. Viscoelastic testing (VET) has gained increasing interest for the characterization of TIC because it provides a more comprehensive depiction of ...
Immune thrombotic thrombocytopenic purpura (iTTP) is a rare autoimmune disorder characterized by severely reduced activity of the von Willebrand factor (VWF)-cleaving protease ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) due to autoantibodies. This leads to the development of pathogenic multimers of VWF, causing a thrombotic microangiopathy with decreased number of platelets, hemolysis, and life-threatening tissue ischemia of mostly brain, heart, a...
