Functional assessment of coronary artery disease by intravascular ultrasound and computational fluid dynamics simulation

Revista Portuguesa de Cardiologia, 2014
Clinical trials have shown that functional assessment of coronary stenosis by fractional flow reserve (FFR) improves clinical outcomes. Intravascular ultrasound (IVUS) complements conventional angiography, and is a powerful tool to assess atherosclerotic

Evaluation of Myocardial Perfusion by Computed Tomography - Principles, Technical Background and Recommendations [PDF]

Arquivos Brasileiros de Cardiologia, 2019
Coronary computed tomography angiography (CCTA) has gained a prominent role in the evaluation of coronary artery disease. However, its anatomical nature does not allow the evaluation of the functional repercussion of coronary obstructions.
