Oxidised LDL and Anti-Oxidised LDL Antibodies Are Reduced by Lipoprotein Apheresis in a Randomised Controlled Trial on Patients with Refractory Angina and Elevated Lipoprotein(a).

An abundance of epidemiological evidence demonstrates that elevated lipoprotein(a) (Lp(a)) represents a significant contributing risk factor towards the development of cardiovascular disease. In particular, raised Lp(a) may play a mechanistic role in patients with refractory angina. Studies have also shown a correlation between oxidised LDL (oxLDL) levels and atherosclerotic burden as well as rates of cardiovascular events.

Lower third chest wall reconstruction in a bilateral sequential lung transplant recipient.

Reconstruction of the sternum following deep sternal wound infection (DSWI) can be challenging, and despite advances in reconstructive surgery, DSWI remains a significant cause of morbidity and mortality in cardiothoracic patients. Transplantation patients present an additional, unique challenge for the reconstructive surgeon. These patients are often on immunosuppressant therapy, with multiple comorbidities, and cannot tolerate prolonged operations for reconstruction.

Echocardiography for left ventricular assist device implantation and evaluation: an indispensable tool.

Echocardiography is an indispensable tool in the evaluation, placement, management and follow-up of patients with left ventricular assist devices (LVAD). While transoesophageal echocardiography is the ideal tool in guiding the implantation procedure, transthoracic echocardiography is essential during the initial evaluation, patient selection and in the post-operative follow-up. This review attempts to summarize which parameters the echocardiographic assessment should focused on during each step.

Case report of asymptomatic very late presentation of ALCAPA syndrome: review of the literature since pathophysiology until treatment.

Background: Anomalous origin of the left coronary artery (LCA) from the pulmonary artery (ALCAPA) is an unusual congenital heart defect which affects approximately 1 in 300 000 live births and accounts for 0.5% of all congenital heart disease. Without surgical intervention, most patients die in infancy (nearly 90%).

Prevalence of cardiovascular events in genetically confirmed versus unconfirmed familial hypercholesterolaemia.

Genetic testing for familial hypercholesterolaemia (FH) is not yet established for widespread use internationally to provide diagnostic confirmation, in part due to high cost and resource requirement. We need to establish whether genetic testing is clinically justified in terms of risk stratification and prediction of cardiovascular events. We performed a single tertiary cardiac centre retrospective evaluation of patients with FH managed within our genetic screening service.

Microstructure of the juvenile sheep aortic valve hinge region and the trilamellar sliding hypothesis.

The aortic valve mechanism performs extremely sophisticated functions which depend on the microstructure of its component parts. The hinge mechanism of the aortic leaflets plays a crucial part in the overall function. However, the detailed microstructure and its relation to function has not been adequately studied.

The Extracellular Matrix-Derived Biomarkers for Diagnosis, Prognosis, and Personalized Therapy of Malignant Tumors.

The tumor biomarkers already have proven clinical value and have become an integral part in cancer management and modern translational oncology. The tumor tissue microenvironment (TME), which includes extracellular matrix (ECM), signaling molecules, immune and stromal cells, and adjacent non-tumorous tissue, contributes to cancer pathogenesis. Thus, TME-derived biomarkers have many clinical applications.

Valvular complications following the Impella device implantation.

Background: Despite clear clinical benefits, there is limited evidence regarding possible complications of the novel mechanical support device Impella. Aortic and mitral valve regurgitation or injury are rare but potential complications following implantation of the Impella device.

Methods: To evaluate valvular complications after the Impella device implantation, we have performed a comprehensive search of literature on multiple sites on this topic.

Bilateral internal thoracic artery use in coronary artery bypass grafting in the post-ART era - Perspective.

There is still lack of convincing evidence about the superiority of bilateral internal thoracic artery (BITA) use in coronary artery bypass grafting (CABG) and BITA grafts continue to be underutilized. Arterial Revascularization Trial (ART) did not demonstrate the superiority of BITA versus single ITA grafting after 10 years. We have reviewed the most recent literature, assessed the current status as well as indications of BITA grafting in the post-ART era.

PC945, a Novel Inhaled Antifungal Agent, for the Treatment of Respiratory Fungal Infections.

Disease due to pulmonary infection remains a significant unmet need, particularly in immunocompromised patients, patients in critical care and those with underlying chronic lung diseases. To date, treatment using inhaled antifungal agents has been limited to repurposing available systemic medicines. PC945 is a novel triazole antifungal agent, a potent inhibitor of CYP51, purpose-designed to be administered via inhalation for high local lung concentrations and limited systemic exposure.

EACVI survey on the management of patients with patent foramen ovale and cryptogenic stroke.

Aims: The European Association of Cardiovascular Imaging (EACVI) Scientific Initiatives Committee performed a global survey to evaluate the current practice for the assessment and management of patients with suspected patent foramen ovale (PFO) and cryptogenic stroke.

Methods And Results: In total, 79 imaging centres from 34 countries across the world responded to the survey, which comprised 17 questions. Most non-invasive investigations for PFO were widely available in the responding centres, with the exception of transcranial colour Doppler which was only available in 70% of sites, and most commonly performed by neurologists.

Impact of malignancy on clinical outcomes in patients with acute coronary syndromes.

Background: The impact of cancer on survival in patients with coronary artery disease has not been well defined. We designed the present study to explore the prevalence and prognostic influence of cancer in patients with acute coronary syndrome (ACS).

Methods: 2'132 patients with ACS were enrolled in the prospective, multicenter Special Program University Medicine ACS (SPUM-ACS) cohort.

Minimally invasive aortic valve replacement with sutureless bioprosthesis through right minithoracotomy with completely central cannulation-Early results in 203 patients.

Objectives: Minimally invasive aortic valve replacement (mini-AVR) might improve clinical outcomes, particularly in high-risk and elderly patients. Sutureless/rapid deployment bioprosthesis can offer advantage of decreasing the cross-clamp time (XCT) and easing the procedure. Our aim was to evaluate the safety and perioperative outcomes of mini-AVR using sutureless bioprothesis via the right minithoracotomy approach with our modified technique of central cannulation.

The missing acute coronary syndromes in the COVID-19 era.

Aims: To determine whether the number of patients presenting with acute coronary syndromes has reduced during the COVID-19 pandemic.

Methods: Numbers of primary percutaneous coronary intervention (PPCI) activations, ST elevation myocardial infarctions (STEMIs) and non-ST elevation myocardial infarctions (NSTEMIs) in a large tertiary Greater London centre and a large district general hospital, both of which have on-site heart attack centres, were collected. We compared the number of PPCI activations, STEMI, NSTEMIs and all MIs prior to the COVID-19 era (January to third week of February 2020), after the start of some COVID-19 restrictions taking place (fourth week of February 2020) and after formal instruction by the United Kingdom Government that all citizens were to observe strict social distancing measures (20 March 2020).

Assessment and pathophysiology of microvascular disease: recent progress and clinical implications.

The development of novel, non-invasive techniques and standardization of protocols to assess microvascular dysfunction have elucidated the key role of microvascular changes in the evolution of cardiovascular (CV) damage, and their capacity to predict an increased risk of adverse events. These technical advances parallel with the development of novel biological assays that enabled the ex vivo identification of pathways promoting microvascular dysfunction, providing novel potential treatment targets for preventing cerebral-CV disease. In this article, we provide an update of diagnostic testing strategies to detect and characterize microvascular dysfunction and suggestions on how to standardize and maximize the information obtained from each microvascular assay.

In Silico and In Vitro Analysis of lncRNA XIST Reveals a Panel of Possible Lung Cancer Regulators and a Five-Gene Diagnostic Signature.

Long non-coding RNAs (lncRNAs) perform a wide functional repertoire of roles in cell biology, ranging from RNA editing to gene regulation, as well as tumour genesis and tumour progression. The lncRNA X-inactive specific transcript (XIST) is involved in the aetiopathogenesis of non-small cell lung cancer (NSCLC). However, its role at the molecular level is not fully elucidated.

Molecular characteristics of uveal melanoma and intraocular tumors.

Malignant melanomas within the eye present different types of metabolic and metastatic behavior. Uveal melanoma (UM) affects a quarter of a million individuals in the USA; however, the molecular pathogenesis is not well understood. Although UV radiation is a risk factor in cutaneous melanomas, it is not crucial for UM progression.

A detailed explantation assessment protocol for patients with left ventricular assist devices with myocardial recovery.

Objectives: Left ventricular assist device (LVAD) implantation for end-stage heart failure patients has been on the rise, providing a reliable long-term option. For some LVAD patients, longer term LV unloading leads to recovery; hence, the need for evaluating potential myocardial recovery and weaning eligibility has emerged.

Methods: All patients who underwent contemporary LVAD explantation at our institution between 2009 and 2020 were included in the study.
