摘要：

The mortality rate due to Cardiovascular Diseases is constantly gaining ground worldwide. Therefore, the early detection of coronary hemodynamic abnormalities is a non-trivial matter in today's clinical practice. The assessment of coronary lesions is made using either invasive imaging techniques or by measuring the Fractional Flow Reserve value which also requires the use of a dedicated pressure wire. In this work, we present our newly developed novel 3-Dimensional Quantitative Coronary Analysis reconstruction method and its' validation by comparing it to an already validated commercial 3D-QCA software. We used the volumes of the 7 3D reconstructed arterial segments as well as the virtual Functional Assessment Index values as validation metrics to compare the two methods. The obtained results show a very high correlation between the two methods presenting very high r(2) values (0.98 and 0.99) and a very strong agreement between them.
