Principal indications for cardiac CT

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 CG9537
As an alternative to invasive coronary angiography prior to heart valve surgery in patients unlikely to require adjunctive coronary artery bypass grafting.ESC72
To assess the functional significance of coronary artery stenoses (by estimating fractional flow reserve).NICE MTG3241
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.ESC72
Before and after surgery/intervention in patients with congenital heart disease.
Assessment of aortic stenosis when echocardiographic parameters are discordant.ESC72
