We studied morphological characteristics of platelets and parameters of platelet aggregation in patients with dilation cardiomyopathy. Augmented aggregatory activity of platelets was found in 76% of patients. In blood of majority of patients we found circulating leukocyte-platelet aggregates. This evidenced for development of inflammatory process and could be related to disturbances of blood rheology. In 2 patients examined by virusological method we revealed presence of a virus inside platelets. This phenomenon might serve as one of possible pathological pathways of disease progression at the account of spread of viral infection along vascular bed during thrombus formation.

Background: Takayasu arteritis is a large-vessel vasculitis, in addition to giant cell arteritis. Various post-operative complications associated with the cardiac macrovasculature have been reported. Detachment of the prosthetic valve, pseudoaneurysm formation, and dilatation of the aortic root are well-known post-operative complications associated with vasculitis syndromes, including Takayasu arteritis.

Background: The optimal treatment of complicated type B aortic dissection (cTBAD) involving arch anomalies remain unclear.
Methods: We consecutively enrolled patients with cTBAD involving arch anomalies who underwent endovascular repair using a single-branched stent graft (SBSG) at our medical center between January 2020 and January 2023. The demographics, clinical manifestation, operation detail, and follow-up outcomes of these patients were retrospectively collected and analyzed.

Background: Silent brain infarctions (SBI) are commonly detected in brain imaging. The association of SBI with rheumatic mitral stenosis (MS) is not clearly relevant. Based on magnetic resonance imaging, we aimed to describe the prevalence of SBI in patients with rheumatic MS and the cardiac abnormalities related to their occurrence.

Aims: Patients with cardiomyopathies are a heterogeneous group of patients who experience high morbidity and mortality. Early cardiac assessment and intervention with access to genetic counselling in a multidisciplinary Cardiomyopathy Clinic may improve outcomes and prevent progression to advanced heart failure.
Methods And Results: Our prospective cohort study was conducted at a multidisciplinary Cardiomyopathy Clinic with 421 patients enrolled (42.
