Non Invasive Imaging

Methods: 23 patients (83% men, 50±16 years) with moderate to severe AR were included. In all patients echocardiography was perfomed for assessment of AR, including EFR-velocity. Ejection fraction (EF), enddiastolic, endsystolic volumes (EDV, ESV) and global longitudinal strain (GLS, normal < -20%) were assessed by 3D-echocardiography. Magnet resonance imaging (MRI) was performed to quantify aortic regurgitation fraction (ARF).
