Principal indications for cardiac CT
| Notes | |
| To evaluate the coronary arteries (by CTCA): stable chest pain with typical or atypical angina, or non-anginal chest pain with ST changes or Q-waves on the resting 12-lead ECG. | NICE CG95 37 |
| As an alternative to invasive coronary angiography prior to heart valve surgery in patients unlikely to require adjunctive coronary artery bypass grafting. | ESC 72 |
| To assess the functional significance of coronary artery stenoses (by estimating fractional flow reserve). | NICE MTG32 41 |
| To evaluate the thoracic aorta: for possible trauma, acute aortic syndrome, aortic dilation, planning and follow-up of aortic intervention. | |
| To evaluate structural heart disease: prior to intervention for structural heart disease, such as transcatheter aortic valve implantation. | ESC 72 |
| Before and after surgery/intervention in patients with congenital heart disease. | |
| Assessment of aortic stenosis when echocardiographic parameters are discordant. | ESC 72 |
