4d Flow Cardiovascular Magnetic Resonance For The Assessment Of Aortic Valve Repair With Ozaki Technique

Introduction: Aortic valve neocuspidalization (Av-Neo) aims to replace the three aortic cusps with autologous pericardium pre-treated with glutaraldehyde and is becoming a valid alternative to traditional aortic valve replacement (AVR). 4D-flow cardiac magnetic resonance (4D-CMR) imaging of patients allows the derivation of shear stress on the aortic wall (WSS). Different studies support the presence of a link between increased WSS at 4D-CMR and the presence of histological alterations of the aortic wall.The purpose of the present work was to compare the WSS of the ascending aorta in patients who underwent Av-Neo vs AVR with biological prostheses.
