Use of intravascular ultrasound (IVUS) in ambiguous angiograms

Introduction

Intravascular ultrasound (IVUS) can resolve abnormalities within the coronary artery to a degree that is not possible with angiography alone. With an axial resolution of 70-200 μm and lateral resolution of 200-400 μm, IVUS can provide information on arterial wall and luminal composition that can change clinical management decisions.

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.

Advances in Imaging and Heart Failure: Where are we Heading?

The increasing prevalence of heart failure requires the establishment of new imaging techniques that are able to diagnose early and guide treatment. With an estimated 825,000 new cases annually in the US, the heart failure burden will continue to rise and is expected to exceed 8 million by 2030.1
