A patient presents with worsening of his general condition, chills and dyspnoea on exertion. With a history of aortic valve replacement, infective endocarditis is suspected, but due to negative imaging by transesophageal echocardiography and negative blood cultures cannot be confirmed. Finally, Cutibacterium acnes prosthetic valve endocarditis is diagnosed after culture of C. acnes during an extended incubation period of blood cultures, the presence of embolic complications and a characteristic finding on PET-CT scan.

Approximately 25% of all ischemic insults are caused by cardiac emboli in atrial fibrillation. Therefore, in patients with atrial fibrillation, oral anticoagulation is initiated or transesophageal echocardiography is performed before electroconversion to exclude blood clots in the heart. This shows that virtually all cardiac thrombi (>90%) are localized in the atrial ear. Therefore, for many decades surgeons have been removing the atrial tube during open heart surgery to eliminate it as a source of emboli. As a minimally invasive alternative, various screens for percutaneous closure of the atrial ear have been developed in the past 10–20 years. The requirements, techniques, and results will be discussed in the following article. [ABSTRACT FROM AUTHOR]

Trees may migrate northward in response to climate change and become exposed to new photoperiod and soil moisture regimes. This study assessed the impacts of photoperiod and its interaction with soil moisture and carbon dioxide concentration ([CO2]) on the hydraulic conductivity in jack pine ( Pinus banksiana Lamb.) and its vulnerability to xylem embolism. Seedlings were exposed to 400 vs. 950 μmol·mol−1 [CO2], 60%-70% vs. 30%-40% (of field capacity) soil moisture, and photoperiods of seed origin and 5° and 10° north of seed origin in greenhouses. Cavitation vulnerability curves were measured for determining the xylem pressure at which 50% hydraulic conductivity was lost (ΨPLC50). It was found that elevated [CO2] significantly increased hydraulic conductivity, whereas low soil moisture decreased it. Under elevated [CO2], the xylem became progressively more vulnerable to embolism with changes in photoperiod regime from the seed origin to 10° north of the seed origin, as indicated by the progressively less negative ΨPLC50. However, no such a trend was detected under the ambient [CO2]. The results suggest that the species may become less resistant to drought as the atmospheric [CO2] increases, hindering the northward migration or seed transfers. Even within its current natural distribution range, trees near its northern boundary of the range may be more vulnerable to embolism as the atmospheric [CO2] increases even without any change in moisture conditions.

Atrial fibrillation (AF) is the most frequently encountered sustained arrhythmia with a prevalence of 0.5–10%, depending predominantly on age. The arrhythmia is associated with significant morbidity and mortality, mainly due to thromboembolic events including stroke and systemic embolisms. These complications can be effectively prevented with anticoagulation therapy either with vitamin K antagonists (VKA) or with non-vitamin K antagonists (NOAC). VKA therapy is effective in preventing strokes but these medications are difficult to use, are associated with significant bleeding risk, and have pharmacokinetic/dynamic properties that make their use cumbersome. NOACs—either factor II or factor Xa inhibitors—have been developed over the past two decades and have been tested against VKA in large randomized controlled trials. This trial evidence was complemented more recently by increasing real-world data comprising several 100,000 patients. Finally, NOACs have been examined for their use in specific clinical situations, for example, in patients undergoing cardioversion, catheter ablation, or coronary interventions. In all of these clinical scenarios, NOACs have been similarly effective or—in many instances—even superior to treatment with VKA. Recent guidelines, therefore, recommend NOAC therapy for stroke prevention in AF as first-line therapy. [ABSTRACT FROM AUTHOR]

Introduction - Papillary fibroelastoma is the most common cardiac tumor with valvular localization, involving more frequently the aortic or mitral valve and much rarely the tricuspid or pulmonary valve. It is the second most common primary cardiac tumor, after myxoma. Many patients are asymptomatic, but the tumor represents a potential source of embolism which explains its clinical importance. Case presentation - We report the case of a 60-year-old woman with nonspecific symptoms in whom a mass attached to the tricuspid valve was found during a routine transthoracic echocardiography, as part of her cardiac evaluation for an elective orthopedic surgical procedure. Multimodality imaging including transesophageal echocardiography and cardiac MRI was afterwards performed. Since the patient had a high global risk of pulmonary embolism, the tumor was surgically removed with preservation of the tricuspid valve and an uneventful postoperative course. The histopathological examination confirmed the diagnosis of papillary fibroelastoma. Conclusion - This case emphasizes the importance of echocardiography as a first-line imaging modality in the diagnosis of cardiac tumors. The embolic risk for papillary fibroelastomas is high and even if the discovery of the tumor is incidental, excision is advisable as surgery has excellent long-term results. [ABSTRACT FROM AUTHOR]

Le myxome cardiaque est une tumeur histologiquement bénigne, souvent découverte fortuitement à l'échocardiographie. Elle reste néanmoins grave par ses complications, notamment emboliques. Nous rapportons le cas d'un myxome de l'oreillette gauche compliqué de syndrome coronarien aigu et de multiples accidents vasculaires cérébraux ischémiques. Le diagnostic d'accidents emboliques est retenu devant l'association d'une tumeur intracardiaque emboligène, des AVCI et un SCA en l'absence de lésions d'athérosclérose et l'absence de thrombus intracardiaque. Le patient a bénéficié d'une exérèse chirurgicale de la tumeur avec des suites opératoires simples. Nous illustrons à travers cette observation le potentiel embolique du myxome qui rend cette tumeur redoutable et nous insistons sur l'intérêt d'une prise en charge chirurgicale urgente.

Abstract: As digital ulcers usually reflect focal ischemia due to a microangiopathy, digital gangrene is more likely to be the consequence of a macroangiopathy which can also sometimes be associated with a microangiopathy. Digital gangrene is a common skin manifestation of connective tissue diseases, especially systemic sclerosis. Other multiple causes are possible: Buerger''s disease, occupational diseases (particularly hypothenar hammer syndrome) or obstructive vascular disease due to subclavian artery embolism or cardiac embolism. More rarely vasculitis, cryoglobulinemia, polycythemia vera and essential thrombocythemia or solid cancer are associated with digital gangrene, sometimes as a first manifestation. Drug-induced digital gangrene should in all cases be checked (particularly bleomycine and interferon alpha). A thorough clinical examination is frequently enough to evoke a specific cause. Cardiac and upper limbs echo-Doppler, biological examination looking for an inflammatory syndrome, an abnormal blood formula, the presence of a cryoglobulinemia, antineutrophil and antinuclear antibodies is mandatory. In some cases, upper limb arteriography is needed to identify a mechanism such as subclavian aneurism or atherosclerotic plaques or to confirm digital arteritis as shown in Buerger''s disease. Limited amputation is frequently needed, but may sometimes occur spontaneously. The main treatment is to treat the cause. [Copyright &y& Elsevier]

Résumé L’embolie paradoxale est une entité rarement démontrée, souvent évoquée, et le diagnostic est présomptif dans la plupart des cas. Le foramen ovale perméable (FOP) est un facteur anatomique prédisposant important pour une telle complication. Nous décrivons le cas d’une patiente ayant un volumineux thrombus enclavé dans le FOP diagnostiqué par l’échocardiographie incluant la modalité 3D, dans un contexte d’embolie pulmonaire aiguë massive. Le traitement n’est pas codifié dans ce contexte, et le thrombus a été extrait avec succès par chirurgie associé à la fermeture du FOP et l’anticoagulation efficace. Paradoxical embolism is rarely demonstrated, often suggested, and the diagnosis has been largely presumptive in most cases. The patent foramen ovale (PFO) is an important predisposing anatomic factor for such a complication. We describe a case where a voluminous thrombus straddling the PFO was diagnosed by echocardiography including the 3D modality, in the setting of acute massive pulmonary embolism. The treatment is not codified in this setting, and the thrombus was successfully removed by surgery, associated with PFO closure, and anticoagulation. [ABSTRACT FROM AUTHOR]

Abstract: Sap is transported under tension (i.e. negative pressure) in trees, according to the tension-cohesion theory. Since water is physically instable under negative pressure, a risk of cavitation is possible. Techniques have been developed during the past two decennia to study cavitation in trees. Trees appear remarkably immune to cavitation events. Cavities form only when extreme water stresses occur or when sap freezes. Nucleation is heterogeneous in trees, presumably caused by the aspiration of air bubbles through conduit walls. Threshold xylem pressures for cavitation vary greatly between species, in concordance with the great functional and ecological diversity of trees. To cite this article: H. Cochard, C. R.
