FFRCT for Complex Coronary Artery Disease Treatment Planning: New Opportunities

Coronary CTA has rapidly gone from a test with potential to be considered a first-line test for patients with stable chest pain.1 It provides robust ability to exclude atherosclerosis and coronary artery stenosis and more recently has been shown to inform and guide clinical treatment making in a fashion that enables a reduction in myocardial infarction when compared to traditional stress testing.2–5 Despite the growing clinical utility data and continued technology improvements, re

Imaging of Valvular Heart Disease in Heart Failure

Heart failure (HF) is a rapidly growing public health problem with an estimated prevalence of more than 26 million people worldwide.1 In developed countries the prevalence is 1–2 % peaking at ≥10 % among people aged over 70 years.2 In the US, the lifetime risk of developing HF is 20 % among people aged 40 years or older.3 Diagnosing the underlying cause of HF is central to the choice of appropriate treatment.

Viewpoint: Recent Advances in Intracoronary Imaging for Vasa Vasorum Visualisation

Vasa Vasorum

The coronary arterial wall generally consists of the tunica intima, tunica media and tunica adventitia. In particular, the coronary adventitia harbours the vasa vasorum (VV),which has a diameter of 50–300 μm and plays an important role as a network of nutrient blood vessels to the arterial wall (Figure 1).1–3

The Changing Paradigm in the Treatment of Structural Heart Disease and the Need for the Interventional Imaging Specialist

Over the past 30 years, several percutaneous transcatheter technologies and devices for interventions in structural heart diseases (SHDs) have been introduced (see Table 1). There are numerous technologies that are in development or are currently being used to treat patients with SHD that use transcatheter techniques. The variety of percutaneous treatment approaches has led to a revolution and evolution in clinical care. The past few years have seen a greater application of novel, catheter-based treatments for SHDs.

Fractional Flow Reserve Measurement by Computed Tomography: An Alternative to the Stress Test

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 alternative to stress imaging.3 Despite this, CCTA alone cannot independently determine the haemodynamic significance of coronary stenosis, as compared with
