    Abstract Background: Cardiac tamponade is a rare but life-threatening complication of cardiac interventions. Despite prompt pericardiocentesis, clinical management can be challenging and sometimes haemodynamic stabilisation is difficult to achieve. Intra-pericardial thrombin injection after pericardiocentesis promotes haemostasis and acts as a sealing agent, as previously described for left ventricular free-wall rupture. We aimed to evaluate intra-pericardial thrombin injection as a bailout strategy for pericardial tamponade following percutaneous cardiac interventions.
    Methods: In a 5-year single-centre retrospective analysis we identified 31 patients with cardiac tamponade due to percutaneous intracardiac procedures. Intra-pericardial thrombin injection as a bailout strategy was administered in 5 of 31 patients (16.1%).
    Results: Patients receiving intra-pericardial thrombin were in a more critical state when thrombin was applied, as demonstrated by a higher rate of resuscitation (40% versus 26.9%) and a trend toward a prolonged stay in the intensive care unit (177.6 ± 84.0 vs 98.0 ± 31.4 h). None of the patients with pericardial tamponades treated with intra-pericardial thrombin needed cardiothoracic surgery. Mortality after 30 days was lower with intra-pericardial thrombin injection than with standard treatment (0% vs 15.4%). We observed no complications using intra-pericardial thrombin.
    Conclusion: Intra-pericardial thrombin injection could be considered as a bailout strategy for patients with iatrogenic pericardial tamponade due to percutaneous procedures. We recommend further evaluation of this technique in the clinical management of refractory pericardial tamponade.

    Abstract Background: We aimed to investigate the anatomical relationship of the coronary sinus (CS) and the mitral valve annulus (MVA) in patients with or without functional mitral regurgitation (FMR) using a multislice CT (MSCT) software to determine (a) the distance and angle of both CS and MVA plane and (b) the mitral annulus geometry.
    Methods: A total of 215 patients with MSCT and CS to MVA topography evaluation were enrolled in this retrospective study.
    Results: This patient cohort included 145 patients without FMR (67.4%, FMR ≤ 1+) and 70 patients (32.6%) with clinically relevant FMR (FMR ≥ 2+). Distance and angulation of CS to MVA planes were highly variable. In all groups, no significant correlation was documented between the distance or angle of CS to MVA planes and left ventricular ejection fraction, left ventricular end-diastolic diameter, or left atrial volume. A significant increase in total CS length could be found in patients with FMR ≥ 2+ compared to the FMR ≤ 1+ group. MVA diameter, area, and perimeter were significantly increased in FMR ≥ 2+ compared to FMR ≤ 1+. In the FMR ≥ 2+ cohort 61% showed a distance of CS to MVA plane <7.8 mm and 58% revealed an angle of CS to MVA plane <14.2°.
    Conclusion: Distance and angulation of CS to MVA topography using an MSCT approach are similar between patients with or without FMR, while CS length, MVA area, MVA perimeter, anterior-posterior diameter, and intercommissural diameter are significantly increased in all FMR subgroups. However, ~60% of FMR ≥ 2+ patients showed favorable CS to MVA topography for indirect mitral annuloplasty.

    Abstract We addressed the question of the influence of the molecular polymorphism of cytokines from different T helper subsets on the susceptibility to SARS-CoV-2 infection. From a cohort of 527 samples (collected from 26 May 2020 to 31 March 2022), we focused on individuals living in the same household (n = 58) with the SARS-CoV-2-infected person. We divided them into households with all individuals SARS-CoV-2 PCR positive (n = 29, households, 61 individuals), households with mixed PCR pattern (n = 24, 62) and negative households (n = 5, 15), respectively. TGF-β1 and IL-6 were the only cytokines tested with a significant difference between the cohorts. We observed a shift toward Th2 and the regulatory Th17 and Treg subset regulation for households with all members infected compared to those without infection. These data indicate that the genetically determined balance between the cytokines acting on different T helper cell subsets may play a pivotal role in transmission of and susceptibility to SARS-CoV-2 infection. Contacts infected by their index persons were more likely to highly express TGF-β1, indicating a reduced inflammatory response. Those not infected after contact had a polymorphism leading to a higher IL-6 expression. IL-6 acts in innate immunity, allergy and on the T helper cell differentiation, explaining the reduced susceptibility to SARS-CoV-2.

    Abstract Objectives: We aimed to compare indirect mitral annuloplasty using the Carillon Mitral Contour System and edge-to-edge repair via MitraClip in atrial functional mitral regurgitation (aFMR).
    Background: In patients with left ventricular dilation, both edge-to-edge repair and indirect mitral annuloplasty are effective in reducing mitral regurgitation, while no clinical trial has compared both interventional methods in aFMR.
    Methods: In a retrospective single-center analysis, 41 patients with aFMR underwent either edge-to-edge mitral valve repair (MitraClip group, n = 20) or indirect annuloplasty (Carillon group, n = 21).
    Results: Both treatment groups showed high procedural success (100%) and low complication rates. Both treatment groups showed a comparable reduction of New York Heart Association (NYHA) classification postimplantation, after 3- and 12-months follow-up. Quantitative reduction in echocardiographic FMR parameters was significantly pronounced in the MitraClip group (reduction in vena contracta MitraClip vs. Carillon: postimplantation -74.6 ± 25.8 vs. -29.1 ± 17.8%, 3-months follow-up -65.8 ± 31.2 vs. -33.9 ± 17.5%, 12-months follow-up -50.8 ± 27.9 vs. -23.9 ± 17.0%, p < 0.05). Qualitative mitral valve assessment showed improved FMR class postimplantation, at 3-and 12-months follow-up in both treatment groups. Edge-to-edge repair revealed better results with lower average FMR classification compared to indirect coronary sinus-based annuloplasty. After 12-months left atrial (LA) volume was significantly reduced in the Carillon group, while in the MitraClip group no LA remodeling was found (reduction in LA volume MitraClip vs. Carillon at 12 months: +9.6 ± 25.1% vs. -12.3 ± 12.7%, p < 0.05).
    Conclusions: Both indirect mitral valve annuloplasty and edge-to-edge repair are feasible and safe in patients with aFMR, while the reduction in FMR was pronounced in the edge-to-edge repair group.

    Abstract Background: Dried non-heat-treated meat treats, such as ears, skin and tails, are popular supplementary dog foods. Previous studies have demonstrated Salmonella spp. contamination on treats, particularly in pig ears and chicken products. This small, exploratory, cross-sectional study investigated Salmonella spp. presence in dried treats available in the UK.
    Methods: A selection of dried treats from local pet shops and online retailers underwent bacterial culture for Salmonella spp. and subsequent antimicrobial susceptibility testing, with Salmonella serotype determined by whole genome sequencing.
    Results: Eighty-four samples were tested, with 16% being Salmonella spp. positive. Five Salmonella serotypes were identified, each associated with specific treat types. An antimicrobial-resistant phenotype was identified in 39% of isolates. All serotypes identified are known to cause human infection.
    Limitations: This study was limited by a small sample size and limited number of retail sources.
    Conclusion: Salmonella spp. of public health concern were present in some dried dog treats in this study. Dog owners, pet food retailers and veterinary professionals should be aware of the potential zoonotic disease risk associated with these treats, and appropriate hygiene measures, including thorough hand washing, should be utilised if they are fed.

    Abstract Objectives: Coronary sinus (CS) based mitral annuloplasty using the Carillon device could be limited by compromise of the left circumflex artery (Cx).
    Background: Computed tomography (CT) might be a feasible tool for preprocedural planning of indirect mitral valve annuloplasty.
    Methods: In a retrospective analysis, 25 patients underwent Carillon device implantation and received CT-angiography (CTA) analysis prior to CS based percutaneous mitral valve repair. We used a retrospective approach with preprocedural CTA and intraprocedural coronary sinus angiography (CSA) measurements to determine the CS to Cx distance at the occlusion or compression point or in the distal landing zone in absence of Cx compromise.
    Results: According to left coronary artery angiography, we identified 7 patients with Cx occlusion, 7 with Cx compression and 11 without Cx compromise. No difference in minimal CS to Cx distance between the three groups could be obtained. Also, neither distal CS diameter nor distal Carillon anchor size were related to Cx impingement. However, ROC analysis identified a CS to Cx distance of <8.6 mm specifically in the distal device landing zone to predict Cx compromise. Furthermore, CTA was accurate in assessing device length in comparison to CSA, but failed predicting Carillon device anchor size.
    Conclusions: CTA derived CS to Cx distance in the device landing zone might be helpful to predict Cx occlusion during Carillon device implantation. Furthermore, CTA predicted CS length but not anchor size correctly. Therefore, CT-angiographic procedural planning might help improving the results of percutaneous CS-based mitral valve repair.
