INTRODUCTION: Global and regional sympathetic activity in the heart can be evaluated using [123 I]meta-iodobenzylguanidine ([123 I]mIBG) imaging. However, [123 I]mIBG is associated with low image spatial resolution and sensitivity in cardiac imaging. We investigated the capability of an F-18-labeled mIBG derivative, meta-(3-[18 F]fluoropropyl)benzylguanidine ([18 F]mFPBG), for identifying ischemic and viable myocardium in a rat model of myocardial infarction. MATERIALS AND METHODS: The ex vivo biodistribution and in vivo metabolic stability of [18 F]mFPBG were investigated in Sprague-Dawley rats...

BACKGROUND: A troponin assay is commonly sent for patients presenting to emergency departments (EDs) with supraventricular tachycardia (SVT). Multiple studies suggest that elevated troponin levels do not predict coronary artery disease in these patients. Patients with elevated troponins are more likely to have additional cardiac testing, which can lead to increased health care costs and unnecessary invasive procedures. OBJECTIVE: Our objective was to evaluate low- to intermediate-risk patients (HEART [history, electrocardiography, age, risk factors and troponin] Score 1-6) presenting to the ED with SVT...

In the current daily practice of acute coronary syndromes, patients experiencing non-ST-elevation acute coronary syndrome (NSTE-ACS) represent the majority of this population. In these patients it is of utmost importance to estimate both ischaemic and bleeding risk, with subsequent, and preferably tailored pharmacological and, if indicated, invasive treatment. In this paper we describe the several risk scores and evaluate which are most applicable to the Dutch health-care system. Furthermore, we provide an overview of the recommended pharmacological treatment in keeping with the European Society of Cardiology guidelines...

Regulation of coronary blood flow is maintained through a delicate balance of ventriculoarterial and neurohumoral mechanisms. The aortic valve is integral to the functions of these systems, and disease states that compromise aortic valve integrity have the potential to seriously disrupt coronary blood flow. Aortic stenosis (AS) is the most common cause of valvular heart disease requiring medical intervention, and the prevalence and associated socio-economic burden of AS are set to increase with population ageing...

This paper provides a practical clinical application of guideline recommendations relating to the inpatient monitoring of patients with acute heart failure, through the evaluation of various clinical, biomarker, imaging, invasive and non-invasive approaches. Comprehensive inpatient monitoring is crucial to the optimal management of acute heart failure patients. The European Society of Cardiology heart failure guidelines provide recommendations for the inpatient monitoring of acute heart failure, but the level of evidence underpinning most recommendations is limited...

The cell plasma membrane Na+ ,K+ -ATPase [NKA] is one of biology's most [if not the most] significant enzymes. By actively transporting Na+ out [and K+ in], it maintains the vital trans-membrane ion concentration gradients and the membrane potential. The forward NKA reaction is shown in the Graphical Abstract [which is elaborated in the text]. Crucially, NKA does not operate in isolation. There are other transporters that conduct K+ back out of [II, Graphical Abstract] and Na+ back into [III, Graphical Abstract] the cell...

Although non-invasive perfusion and viability imaging often provide the gateway to coronary revascularisation, current non-invasive imaging methods only report the surrogate markers of inducible hypoperfusion and presence or absence of myocardial scar, rather than actually visualising areas of ischaemia and/or viable myocardium. This may lead to suboptimal revascularisation decisions. Normally respiring (viable) cardiomyocytes convert pyruvate to acetyl-CoA and CO2 /bicarbonate (via pyruvate dehydrogenase), but under ischaemic conditions characteristically shift this conversion to lactate (by lactate dehydrogenase)...

INTRODUCTION: Aortic valve stenosis (AS) is the most common valvular pathology in the elderly. Surgical aortic valve replacement (AVR) remains the gold-standard of treatment for AS. However, emerging transcatheter aortic valve replacement (TAVR) has become an increasing alternative to surgery. In a recent survey from the European Society of Cardiology, 9,4% of the physicians stated that age was the main reason to propose for a TAVR instead of surgery. METHODS: We performed a single-center retrospective study including 353 patients (149 patients over 80 years-old, compared to 204 patients between 60-69 years-old) consecutively submitted to AVR between January 1, 2013, and December 31, 2016, to compare the results of both groups in AVR surgery and how we can improve surgery outcome in older patients...

Direct oral anticoagulants (DOAC) possess high bioavailability, and their anticoagulant effect is more predictable than that of vitamin K antagonists, hence they do not require routine dose adjustment based on laboratory testing. However, there are circumstances when laboratory testing may be useful, including patients who need to undergo surgery or invasive procedures. Most guidelines state that patients on DOAC may safely undergo surgery/invasive procedures by stopping anticoagulation for a few days before intervention without testing if renal function is within normal limits...

Current clinical guidelines emphasize the unmet need for technological innovations to guide physician decision-making and to transit from conventional care to personalized cardiovascular medicine. Biomarker-guided cardiovascular therapy represents an interesting approach to inform tailored treatment selection and monitor ongoing efficacy. However, results from previous publications cast some doubts about the clinical applicability of biomarkers to direct individualized treatment. In recent years, the non-coding human transcriptome has emerged as a new opportunity for the development of novel therapeutic strategies and biomarker discovery...

Congenital heart interventions are now replacing surgical palliation and correction in an evolving number of congenital heart defects. Right ventricular outflow tract and ductus arteriosus stenting have demonstrated favorable outcomes compared to surgical systemic to pulmonary artery shunting, and it is likely surgical pulmonary valve replacement will become an uncommon procedure within the next decade, mirroring current practices in the treatment of atrial septal defects. Challenges remain, including the lack of device design focused on smaller infants and the inevitable consequences of somatic growth...

Sleep apnea is associated with increased cardiovascular risk and may be important in atrial fibrillation (AF) management. It is present in up to 62% of the AF population and is highly under-recognized and underdiagnosed. Obstructive sleep apnea (OSA) is strongly associated with AF and non-randomized trials have shown that its treatment can help to reduce AF recurrences and maintain sinus rhythm. The 2016 European Society of Cardiology guidelines for the management of AF recommend that AF patients should be questioned regarding the symptoms of OSA and that OSA-treatment should be optimized to improve AF treatment results...

We present a case of a 63-year-old patient referred to a cardiology consultation due to progressive symptoms of heart failure. He had a history of an inferior ST elevation acute myocardial infarction 6 years ago. Echocardiogram revealed a giant left ventricular aneurysm/pseudoaneurysm involving the inferior and inferolateral left ventricular walls, with a massive mural thrombus. Additional characterization was done by cardiac magnetic resonance, essential in establishing the diagnosis of pseudoaneurysm and to guide subsequent management...

Minimally invasive surgical mitral valve repair (MVRepair) has become routine for the treatment of mitral valve regurgitation, and indications have been expanded to include reoperations. Current European Society of Cardiology/European Association for Cardio-Thoracic Surgery guidelines for the management of valvular heart disease recommended standards in terms of mitral valve disease differentiation, timing of intervention and surgical techniques to improve patient care. Numerous minimally invasive techniques to lessen the invasiveness have been described, such as the minimal-access J-sternotomy (ministernotomy), the parasternal incision, the port-access technique and the right minithoracotomy...

For the first time, the European Society of Cardiology and the European Association for Cardio-Thoracic Surgery have joined forces to develop consensus guidelines for the management of atrial fibrillation (AF). One of the main issues is the integrated care of patients with AF, with emphasis on multidisciplinary teams of general physicians, cardiologists, stroke specialists and surgeons, together with the patient's involvement for better management of AF. These guidelines also help in the detection of risk factors and concomitant cardiovascular diseases, stroke prevention therapies, including anticoagulation and antiplatelet therapies after acute coronary episodes, major haemorrhages or strokes...

The population of patients with congenital heart disease (CHD) is continuously increasing with more and more patients reaching adulthood. A significant portion of these young adults will suffer from arrhythmias due to the underlying congenital heart defect itself or as a sequela of interventional or surgical treatment. The medical community will encounter an increasing challenge as even most of the individuals with complex congenital heart defects nowadays become young adults. Within the past 20 years, management of patients with arrhythmias has gained remarkable progress including pharmacological treatment, catheter ablation, and device therapy...
