Is emergency transseptal transcatheter mitral valve-in-valve implantation feasible in patients on ECMO?
Emergency transseptal transcatheter mitral valve-in-valve implantation is feasible even with ECMO support, but clinicians must be aware of the risk of valve migration and late entrapment.
Transseptal transcatheter mitral valve-in-valve implantation is feasible, even in an emergency setting with ECMO. Valve migration in the left atrium may occur and lead to late entrapment in a "reverse position", with significant haemodynamic consequences.
Fassa et al. (2013) studied this question.
