What cardiac intervention has taken place?
Transcatheter aortic valve replacement (TAVR); specifically, with a Medtronics CoreValve.
What are routes of access for placement of this device?
Currently (2014), transfemoral, transaortic, and transaxillary routes are possible.
What aortic valve area is considered "severe" stenosis?
Below 1.0 cm^2 (0.6 - 0.7 cm^2 is considered in the range of "critical" stenosis)
Is this TAVR MRI safe?
It is "MR conditional" (neither absolutely safe nor absolutely unsafe). Always check the updated safety profile of medical devices before assuming they are safe in an MRI magnet.
