Description
Summary:[...]a balance between PM need and PVL would be an appropriate objective of a head-to-head device trial. Again, aortography allows assessment of PVL and of depth of implantation, simultaneously. [...]aortography could be a better option than MRI for device comparisons in this context. Furthermore, atrial fibrillation, which was reported in almost one-third of the patients in this paper, reduces the accuracy of flow measurements on MRI. [...]both phase contrast quantification of AR as well as volumetric quantification could be imprecise.
