    Research into biodegradable polymeric stents: a review of experimental and modelling work

    Tianyang Qiu , Liguo Zhao
    Bioresorbable stents (BRSs) are regarded as the next-generation medical devices to treat blocked or diseased arteries. The use of BRSs aims to reduce the risk of late stent thrombosis and long-term tissue inflammation associated with permanent metallic stents. BRSs are designed to relieve symptoms immediately and also provide mechanical support for an appropriate time period before they are fully absorbed by human body. To promote clinical adoption of BRSs or even to substitute metallic stents, the mechanical performance of BRSs needs to be thoroughly investigated and quantitatively... Read more

    Bortezomib-induced posterior reversible encephalopathy syndrome: a case report

    Paolo Candelaresi , Maria Chiara Casorio
    Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurological syndrome due to autoregulation breakthrough with subsequent predominantly vasogenic oedemain associated with several clinical conditions. It is being increasingly reported in antineoplastic-treated patients. Here we report the case of a 72-year-old man who developed PRES during the second cycle of bortezomib treatment for multiple myeloma. Unlike usual PRES cases, only moderate hypertension was present at symptom onset, supporting the hypothesis that alterations of the vascular endothelium and... Read more

    The first INSPIRIS RESILIA Aortic ValveTM replacement (Edwards Lifesciences) in endocarditis

    Sanjeet Singh Avtaar Singh , Gwyn Beattie , David Reid , Philip Curry
    There is an increasing number of patients who have surgery during the active phase of infective endocarditis. Despite the decreasing in-hospital mortality and increasing early intervention rate, optimal timing for surgery remains a difficult decision. For patients with mental illnesses, the choice of valve is another factor to consider as non-adherence may lead to serious adverse events Antipsychotic medications may also alter the metabolism of vitamin K antagonists increasing the risk of stroke or major haemorrhage. We report a case of a 19-year-old man with a history of Ehlers-Danlos... Read more

    Repair of mitral subvalvular apparatus and a calcified left ventricle aneurysm

    Kasra Shaikhrezai , Sanjeet Singh Avtaar Singh , Karim Morcos , Steve Hunter
    Left ventricle (LV) myocardial infarction may result in changes to the structure of the subvalvular apparatus. This may lead to a functional regurgitation if accompanied by annular dilatation preventing coaptation of leaflets. Scar tissue formation in the left ventricle may also lead to aneurysm of the left ventricle. This can then calcify, making repair of the leaflet technically challenging. We present a case of a mitral valve repair with concomitant repair of left ventricle aneurysm in a 75-year-old gentleman who suffered an ST-segment elevation myocardial infarction to the lateral wall...

    Ruptured isolated descending thoracic aortic aneurysm: open or endovascular repair?

    Amer Harky , Nichola Manu , Rafal Al Nasiri , Dilan Sanli , Ciaran Grafton-Clarke , Jeffrey Shi Kai Chan , Chris Ho Ming Wong
    Descending thoracic aortic aneurysm management has gained momentum and became a topic of many debates at international levels since the evolution of endovascular repair. Ruptured descending thoracic aortic aneurysm is a clinical emergency which is associated with high mortality and morbidity rates if not managed properly. Prior to thoracic endovascular aortic repair (TEVAR), open repair (OR) was the gold standard management, however since the evolution of TEVAR, this has changed. Several centers have reported many of their experiences and published that TEVAR can provide equal or even... Read more

    Temporizing amplatzer closure of an aorto-enteric fistula associated with a blind aortic stump via a translumbar approach

    S. Keisin Wang , Justin R. King , Ashley R. Gutwein , Raghu L. Motaganahalli , Andres Fajardo , Gary W. Lemmon
    We present a case of an aorto-enteric fistula (AEF) with chronic, persistent bleeding from a blind aortic stump managed by endovascular means. This novel approach may have extended the life of a patient who would otherwise have been subject to a high perioperative morbidity or persistent bleeding and death. While our patient ultimately expired, we believe this technique can be considered for temporization in highly-selected patients. Read more

    Traumatic pulmonary artery injury: a review of the recent literature

    Youichi Yanagawa , Kouhei Ishikawa , Hiroki Nagasawa , Ikuto Takeuchi , Kei Jitsuiki , Hiromichi Ohsaka , Kazuhiko Omori
    Pulmonary artery injury (PAI) is rare, lethal clinical entity. Traumatic PAI is anatomically classified into transection/rupture/laceration, pseudoaneurysm, dissection and fistula. In addition, traumatic PAI is clinically classified into two major categories: iatrogenic and non-iatrogenic, depending on the mechanism of the trauma. The frequency, clinical symptoms and treatment differ between the two clinical categories. If PAI can be managed appropriately and promptly in patients without cardiac arrest, the patient may be saved, as PAI can be easily controlled with appropriate procedures... Read more

    Energetic metabolism in cardiomyocytes: molecular basis of heart ischemia and arrhythmogenesis

    María Sofía Martínez , Andrés García , Eliana Luzardo , Mervin Chávez-Castillo , Luis Carlos Olivar , Juan Salazar , Manuel Velasco , Joselyn Joanna Rojas Quintero , Valmore Bermúdez
    Cardiac muscle contraction is a strictly regulated process which conjugates a series of electrophysiological, biochemical and mechanic events, resulting in the pumping of blood to all bodily tissues. These phenomena require a very high energetic demand both for generating the necessary mechanical force, and for maintaining cellular homeostasis during the process. In the myocardium, fatty acids (FA) represent the main energy substrate, although other secondary substrates, such as glucose and ketone bodies, may also be used. Nevertheless, under certain conditions such as heart failure or... Read more

    HDL subfraction distribution and HDL function in untreated dyslipidemic patients

    Mariann Harangi , Anita Szentpéteri , Bíborka Nádró , Hajnalka Lőrincz , Ildikó Seres , Dénes Páll , György Paragh
    Aim: The protective role of high-density lipoprotein (HDL) against atherosclerosis is well known. However, both structural and functional changes of the HDL particles may affect its protective efficacy. Increased levels of HDL-associated myeloperoxidase (MPO) and decreased HDL-linked paraoxonase-1 (PON1) activity have been reported in dyslipidemic patients. Some changes in HDL subfraction distributions were also studied previously, but data on structural and functional changes in dyslipidemia are not complete. Therefore, the authors aimed to evaluate these qualitative and quantitative... Read more
