Key result
TriCinch tricuspid repair proves feasible and reduces EROA by ~50% in a prior MitraClip patient.
Why the study?
In high-risk patients undergoing transcatheter mitral valve interventions with concomitant severe tricuspid regurgitation, the tricuspid valve is typically left untreated despite guideline recommendations for concomitant treatment during left sided valve surgery.
Case Report (n=1)
Transcatheter tricuspid repair using the TriCinch system is feasible as a staged procedure for severe TR following MitraClip, though simultaneous treatment may be preferable in selected patients.

Single-case TriCinch experience suggests feasibility in high-risk mitral patients; hypothesis-generating and leaves open need for prospective trials.
Taramasso et al. (2016) conducted a case report in Severe tricuspid regurgitation (n=1). Transcatheter tricuspid valve repair using the TriCinch System was evaluated on Reduction in tricuspid regurgitation and effective regurgitant orifice area (EROA). Transcatheter tricuspid repair using the TriCinch System was feasible and reduced the effective regurgitant orifice area by 50%, resulting in mild residual TR in a patient with prior MitraClip.
