Key result
Mitral valve-in-ring implantation successfully treats concurrent trans-ring and para-ring regurgitation from ring dehiscence.
Why the study?
Valve-in-ring transcatheter mitral valve implantation had been described to treat either trans-ring or para-ring regurgitation jets individually, but not both concurrently.
Can valve-in-ring transcatheter mitral valve implantation successfully treat concurrent trans-ring and para-ring mitral regurgitation due to annuloplasty ring dehiscence?

Can valve-in-ring transcatheter mitral valve implantation successfully treat concurrent trans-ring and para-ring mitral regurgitation due to annuloplasty ring dehiscence?
Valve-in-ring transcatheter mitral valve implantation can safely and effectively treat concurrent trans-ring and para-ring regurgitation caused by annuloplasty ring dehiscence.

ViR TMVI may treat mixed MR from ring dehiscence; hypothesis-generating and requires prospective validation.
BACKGROUND: Annuloplasty failure caused by ring dehiscence can lead to trans-ring and para-ring mitral regurgitation (MR). Transcatheter treatments are available for patients at prohibitive risk of surgery. In patients unsuitable for edge-to-edge repair, valve-in-ring (ViR) transcatheter mitral valve (MV) implantation has been described to treat trans-ring or para-ring jets but not both concurrently. CASE SUMMARY: A 78-year-old male presented with severe MR due to dehiscence of a 34 mm Edwards Physio II mitral annuloplasty ring. Transoesophageal echocardiography showed two jets of regurgitation; trans-ring and para-ring. Repair was successfully undertaken with a ViR procedure (29 mm S3 Edwards Lifesciences). DISCUSSION: Patients with failure of MV annuloplasty with trans-ring and para-ring regurgitation can be safely and effectively treated by ViR transcatheter MV implantation.

Sharma et al. (2021) conducted a case report in Severe mitral regurgitation due to annuloplasty ring dehiscence (n=1). Valve-in-ring transcatheter mitral valve implantation was evaluated on Resolution of mitral regurgitation. Valve-in-ring transcatheter mitral valve implantation successfully treated concurrent trans-ring and para-ring regurgitation caused by annuloplasty ring dehiscence.
