• Eligibility for PCI due to angina

• Anatomical evidence of significant multi-vessel coronary stenosis defined by either:

∙ ≥70% stenosis in two or more coronary arteries of ≥2.5mm visual diameter stenosis, on invasive coronary angiography (ICA)

‣ Severe stenosis in ≥2 coronary arteries of ≥ 2.5mm visual diameter stenosis, on CTCA

• Physiological evidence of ischaemia with a positive test corresponding to the coronary arteries to be stented, on at least one of the following:

‣ dobutamine stress echocardiogram

⁃ cardiac MRI

⁃ myocardial perfusion study

⁃ invasive metrics of coronary physiology
