New Patient-specific Functional Assessment of the Anomalous Aortic Origin of Coronary Arteries.

The coronary blood flow and its distribution between the anomalous and normal artery will be measured by invasive coronary catheterization. Coronary artery flow will be calculated based on intravascular ultrasound (IVUS) and pressure difference measurements. After the IVUS assessment, a pressure transducer (FFR/iFR probe) will be inserted in the coronary artery for pressure measurements. The measurements will be done in the anomalous and normal coronary arteries in each patient to determine coronary flow distribution. Patient's specific heart parameters will be retrieve from CT, MRI and other diagnostic tests and integrated in the simulation module.
