Abstract
Transcatheter, transarterial aortic valve implantation (TAVI) is rapidly emerging as a promising new treatment option for patients with severe symptomatic aortic valve stenosis who are considered at high or prohibitive surgical risk [1,2]. Envisioning real-time MR guidance of the TAVI procedure, the objective of this study was the systematical
Highlights
Featuring the modified MR compatible stent valve delivery device, real-time MR guided transarterial aortic valve implantation (TAVI) has been performed in vivo in eight swine
Replacement of the commercial delivery device by the re-designed delivery device resulted in artifact elimination and excellent real-time visualization of catheter movement and valve deployment
MR-guided TAVI was successful in 6/8 swine (Figure 1)
