With ageing of the general population and broadening indications, the number of pacemaker recipients is steadily increasing. The incidence of cardiac implantable electronic device (CIED) infection, a dreaded major complication, is also rising.1 The diagnosis is based on the presence of an abscessed pocket, cutaneous breakthrough of the pulse generator or vegetations attached to the pacemaker lead… View more

Acute coronary syndromes (ACS) and heart failure (HF) are both associated with complex neurohormonal activation. Commensurate with advances in pharmacological and device therapies for both conditions, the concept of using circulating biomarkers for diagnosis and risk stratification, as well as for targeting and monitoring therapy, has received great attention. Although many novel biomarkers have… View more

B-type natriuretic peptide (BNP) and N-terminal prohormone brain natriuretic peptide (NT-proBNP) have been shown to be extremely helpful in the diagnosis and management of patients with heart failure (HF). These neurohormones are secreted from both the left and the right cardiac ventricle in response to ventricular volume expansion and pressure overload. BNP and NT-proBNP can be seen as… View more

Computed tomography coronary angiography (CTCA) has entered the level of daily clinical practice in many institutions worldwide. All studies previously performed on the diagnostic accuracy of CTCA have shown a high negative predictive value, indicating a high ability of this method to exclude relevant coronary artery disease.1–3 However, CTCA is highly demanding not just of the technology, but… View more

Systemic atherosclerosis involves all major arterial vessels, including the carotid and intracranial arteries, coronary circulation, thoracic and abdominal aorta, internal iliac arteries, renal arteries and peripheral vasculature. This generalised disease contributes to cardiac ischaemic disease, stroke, limb loss and a range of other illnesses, and is the major cause of morbidity and mortality… View more

Myocardial perfusion imaging (MPI) using combined computed tomography (CT) and single-photon emission CT (SPECT) systems plays an important role in the management of patients with coronary artery disease (CAD).1–4 The method can be used to assess myocardial perfusion and left ventricular function simultaneously. It is an especially valuable tool for assessing short-term risk of CAD, thus… View more

Since the introduction in the early 1980s of magnetic resonance imaging (MRI) in clinical practice, contrast agents (CAs) have been part of MR studies enhancing the capabilities of this diagnostic technique. CAs enhance the contrast between different types of tissues. Tissue contrast depends largely on proton concentration and longitudinal (T1) and transversal (T2) relaxation times inherent to… View more

Since the introduction of multislice computed tomography (MSCT) in 1998, non-invasive cardiac imaging has developed rapidly. In the recent past, two different objectives can be observed in the technological development of cardiac MSCT. On the one hand, the number of detector rows was increased up to 320 in single-source scanners in order to ensure simultaneous coverage of the entire heart with a… View more

Over the last decades, important efforts have been made to miniaturise echocardiographic machines without losing too much accuracy. The first step was to move from big cumbersome machines to echocardiographic laptops. Recently, hand-held ultrasound machines have been developed (see Figure 1). This evolution should facilitate point-of-care cardiac ultrasound – that is, ultrasonography performed… View more
