The increased incidence of coronary artery disease, as well as the advances in device technology and improved potentialities of percutaneous coronary intervention (PCI), have resulted in a dramatic rise in the number of invasive coronary procedures (both diagnostic catheterisations and PCIs).1 These procedures normally used the transfemoral access, which involves the insertion of a catheter…

An Introduction to Radiation
X-rays, so-called because their nature was at the time unknown, were discovered by the German physicist Wilhelm Roentgen in 1895, one year before the discovery of ‘natural’ radioactivity by Henri Becquerel.1
X-rays found application in radiography a few years after their discovery, although the first side effect attributed to radiation injury (depilation) had been…

Today, in industrialised countries, we are treating more and more patients with coronary artery disease or structural heart disease, due, in part, to an increase in life expectancy over the last 50 years, as well as an increasing incidence of risk factors such as diabetes and obesity. Accordingly, there has been a rise in the use of contrast-enhanced diagnostic imaging and interventional…

With the increasing use of contrast agents for both diagnostic and interventional procedures, contrast-induced acute kidney injury (CI-AKI) has become an important medical concern. It is estimated that CI-AKI is the third most common cause of hospital-acquired renal failure and has significant prognostic implications for patients outcomes.1 The incidence of CI-AKI varies depending on the…

Intracoronary imaging is able to aid the interventional cardiologist in the characterisation of atherosclerotic plaque morphology, in optimising stent sizing, and in minimising the complications associated with percutaneous coronary intervention (PCI). Intravascular ultrasound (IVUS) and optical coherence tomography (OCT) are commonly used methods, while newer spectroscopic methods are under…

Coronary angiography has been the gold standard technique for evaluating coronary arterial disease for the past 50 years. Increasingly, however, realisation of the limitations of coronary angiography, mainly the inability to supply information regarding the coronary wall, has prompted the design and development of adjunctive technologies to better evaluate not just luminal disease but also the…

Coronary computed tomography angiography (CCTA) is a noninvasive tool capable of directly visualising the coronary anatomy with high sensitivity and negative predictive value (NPV) for coronary artery disease (CAD) compared to invasive coronary angiography (ICA).1,2 Recent innovations in computed tomography (CT) technology have led to the rapid development of CCTA and its selection as an anatomic…

The rapid development of percutaneous coronary and peripheral vascular interventional technologies, as well as non-invasive computed tomography (CT)-based imaging systems, has led to a dramatic increase in the number of patients receiving intravenous or intra-arterial contrast media (CM). It has been estimated that more than 80 million doses (8 million litres) of contrast material are…
