Do we need novel approaches to the non-invasive diagnosis of coronary-artery disease?
The arsenal of non-invasive diagnostic tools for the workup of suspected coronary-artery disease seems well stocked: electrocardiography and echocardiography during rest and stress as well as nuclear cardiology are widely available. However, all of these techniques have an important limitation: they do not permit direct visualization and quantification of coronary-artery stenoses, but rather rely on the detection of functional consequences caused by flow-limiting lesions. Haemodynamically insignificant stenoses cannot be detected.
Cardiac catheterization with selective coronary angiography remains the gold standard for the assessment of the presence and severity of coronary-artery disease. This very frequently performed procedure, even though invasive, has a low procedure-related morbidity and mortality: severe adverse events such as acute myocardial infarction, stroke, or malignant arrhythmias are reported in less than 1%, death in less than 0.15% [1]. In the context of cardiac catheterization, intravascular ultrasound (IVUS) can be used to investigate precisely the coronary vessels
