Recent advancements have introduced thinner coatings for increased flexibility and improved biocompatibility. The aim herein was to assess the safety and performance of a highly flexible cobalt-chromium stent covered with polytetrafluoroethylene (PTFE) in a preclinical model.Methods: In total 6 PTEF-covered stent grafts 6mm x 38mm cobalt-chromium, (Solaris BXTM, Scitech Produtos Medicos) were implanted compared to 5 controls ( BeGraftTM, Bentley InnoMed GmbH) in the iliac arteries of 11 swine. Stents were evaluated with angiography, high-definition IVUS, and histology for 28 days.Results: All animals underwent successful implantation with 100% survival at follow-up. At 28 days, there was no statistically significant difference in MLD compared to baseline in both groups (test, 5.2 ± 0.7 mm vs 5.3 ± 0.6 mm, p = 0.8; control, 4.9 ± 0.7 mm vs 5.1 ± 0.5 mm, p = 0.8), indicating no LLL (test, -0.2 ± 0.16 vs control, -0.18 ± 0.16 mm; p = 0.8). IVUS revealed a tendency for the less neointimal area in the test group (3.75 ± 0.9mm² vs 5.69 ± 2.2 mm²; p = 0.08), resulting in a tendency toward higher % AS in the control arm (14.07 ± 3.42% vs 20 ± 7%; p = 0.1). Microscopic evaluation revealed minimal vascular injury (test 0.1 ± 0.3 vs control 0.1 ± 0.1) and complete endothelialization coverage (test, 3.2 ± 0.8 vs control 3.8 ± 0.3) in both groups, with minimal inflammation(test vs. control: per strut 0.02 ± 0.06 vs. 0.14 ± 0.22; neointimal 1.2 ± 0.6 vs 1.1 ± 0.4; medial 0.3 ± 0.4 vs 0.3 ± 0.4).Conclusion: Solaris BXTM demonstrated highly flexible and biocompatible, with minimal vascular injury, and reduced neointimal hyperplasia compared to the control.","PeriodicalId":93923,"journal":{"name":"Cardiology journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144188702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The prognosis for untreated CTEPH patients is poor because it leads to elevated pulmonary artery pressure and right heart failure. Early and accurate diagnosis of CTEPH is crucial because it remains the only form of PH that is potentially curable. However, diagnosing CTEPH is often challenging and frequently delayed or misdiagnosed. This review discusses the current role of multimodal imaging in diagnosing CTEPH, guiding clinical decision-making, and monitoring post-treatment outcomes. The characteristic findings, strengths, and limitations of various imaging modalities, such as computed tomography, ventilation-perfusion lung scintigraphy, digital subtraction pulmonary angiography, and magnetic resonance imaging, are evaluated. Additionally, the role of artificial intelligence in improving the diagnosis and treatment outcomes of CTEPH is explored. Optimal patient assessment and therapeutic decision-making should ideally be conducted in specialized centers by a multidisciplinary team, utilizing data from imaging, pulmonary hemodynamics, and patient comorbidities.","PeriodicalId":93923,"journal":{"name":"Cardiology journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144176121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to analyse the concentration of Klotho and FGF23 proteins in patients with myocardial infarction (MI).Methods: The study group comprised 129 patients diagnosed with acute coronary syndrome (ACS), who were referred for further invasive diagnostics (MI group). Blood samples were collected at 4 time points: at admission, and 6h, 24h, and between 24-48h post-admission. The criteria for the control subjects (n = 30) were no declaration of MI and ACS (non-MI group).

Klotho concentration was also significantly increased in patients with ST-segment elevation MI (STEMI) only at admission, in comparison to non-ST-segment elevation MI (NSTEMI). The concentration of FGF23 in the MI group was higher at admission, 6h and 24h post-admission, and continued to increase after 24-48 h. There was an increase in FGF23 concentration in the STEMI group at 24-48h post-admission, in comparison to NSTEMI.Conclusions: The concentrations of Klotho and FGF23 in plasma were higher in patients with MI and changed over time.

The coronary microvasculature was assessed by angiography-derived index of microcirculatory resistance (caIMR) using commercial software. The primary endpoint was major adverse cardiovascular events (MACE) defined as a composite of all-cause death and myocardial infarction.Results: The median symptom-to-angiography time was 149 hours (interquartile range [IQR], 101-192).

However, co-occurrence of DCM and non-obstructive coronary atherosclerotic plaque is frequent. Our objective was to evaluate the coronary artery dimensions and their relation to the left ventricle mass in DCM patients with excluded coronary atherosclerosis.Methods: Out of 426 patients with DCM who underwent computed coronary tomography angiography (CCTA), we identified 34 without signs of coronary atherosclerosis and compared them with 193 consecutive patients without DCM and atherosclerosis in CCTA. They were matched one to three by sex, coronary dominance pattern, and body-surface area (BSA). Left ventricle myocardial mass (LVMM) and proximal and middle coronary artery segment dimensions were evaluated with the use of dedicated, commercially available software.Results: Overall, coronary segment dimensions were not different between groups except for the medial left anterior descending segment and obtuse marginal, which were wider in the DCM group, while the proximal right coronary artery was larger in the non-DCM group. Total coronary artery volume (CAV) and LVMM/CAV ratio were greater in the DCM group (2879 [2535-3508] mm³ vs. 2521 [2120-3115] mm³, p = 0.03) and (0.062 [0.054-0.074] g/mm³ vs. 0.049 [0.039-0.058] mm³, p = 0.0002), respectively. Also, the LVMM/coronary artery ostial area (COA) ratio was larger in patients with DCM (5.4±1.3 g/mm² vs. 3.7 ± 1.1 g/mm², p < 0.0001).

Herein we report our experience with secondary interventional treatment.Methods: From July 2020 to January 2023, patients who underwent PFO occlusion for more than one year with residual right-to-left shunting (rRLS) screened by contrast transthoracic echocardiography (cTTE) constituted the study population. A retrospective analysis of the basic, procedural, and follow-up data was performed.Results: A total of 35 patients with large rRLS were admitted to our center. Fourteen patients underwent transcatheter rRLS closure. Transesophageal echocardiography (TEE) clearly showed the color blood flow profile, and cTEE showed a large rRLS in 12 cases. TEE showed a small outlet near the left exit of the rRLS, and cTEE showed a small rRLS in two cases. Type I rRLS accounted for 71.4%, residual PFO, and residual atrial septal defect (ASD) for 14.3%, respectively. Secondary transcatheter interventions were successful in 12 patients (85.7%). No complications were observed. Six cases of type I rRLS were closed with ASD occluders and two with an ADO-II device. Two residual PFO and two residual ASD were implanted with PFO occluders. cTTE was performed six months after the procedure, with complete closure in 12 patients.Conclusion: TEE not only helps to improve interventional strategies to reduce residual shunt in primary occlusion but also helps in the screening of patients who are truly suitable for secondary intervention.

Heparins, vitamin K inhibitors, and direct oral anticoagulants (DOACs) are well-established drug classes that help prevent thromboembolic complications. While effective, they pose significant risks during long-term therapy, including bleeding, osteoporosis, heparin-induced thrombocytopenia, and the need for frequent monitoring and dose adjustments. Factor XI (FXI) inhibitors represent an innovative approach in anticoagulation therapy, aiming to balance thromboembolic events with the risk of bleeding complications. They include: a) orally administered small molecule inhibitors such as milvexian and asundexian; b) monoclonal antibodies such as abelacimab, osocimab, and xisomab, which specifically bind and inactivate FXI; c) FXI-antisense oligonucleotide (FXI-ASO), which downregulate FXI synthesis at the mRNA level and reduce plasma FXI concentrations. Available data indicate that FXI inhibitors decrease the risk of thromboembolic events and are associated with a lower incidence of major bleeding than current gold standard methods. Hence, FXI inhibitors may become the preferred anticoagulant class, especially for patients with elevated bleeding risk. Their development is an important step in the history of anticoagulant therapy, striving to find a balance between preventing thromboembolism and reducing bleeding risk, ultimately improving patient outcomes. In this context, a discussion on the characteristics of FXI inhibitors, a summary on data regarding the efficacy and safety of FXI inhibitors based on preclinical and clinical studies, and an outline of future perspectives regarding therapeutic strategies of FXI inhibition in venous thrombosis are presented in this study.","PeriodicalId":93923,"journal":{"name":"Cardiology journal","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144000527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
