Key result
Second prosthesis placement appears safe to avoid surgery for delayed Portico valve migration after TAVR.
Why the study?
Valve migration after TAVR is an unusual but life-threatening complication that usually occurs during or shortly after the procedure, requiring experienced rescue treatments.
Case Report
Placement of a second prosthesis is a safe salvage strategy for delayed down migration of a TAVR valve, avoiding the need for surgical conversion.
May offer bailout for TAVR migration; hypothesis-generating and should not yet change practice.
There are some complications after transcatheter aortic valve replacement (TAVR), which is an alternative to surgery for the treatment of severe aortic stenosis. Valve migration, an unusual but life-threatening complication of TAVR, usually occurs during or several hours after the procedure and is associated with poor outcome. Therefore, operators must be experienced in rescue treatments. Placement of a second prosthesis as a salvage strategy appears to be a safe method to avoid the need for conversion to surgery.

Şengör et al. (2024) conducted a case report in Severe aortic stenosis with TAVR complication (valve migration). Placement of a second prosthesis was evaluated. Placement of a second prosthesis as a salvage strategy for delayed down migration of a Portico valve after TAVR appears to be a safe method to avoid conversion to surgery.
