Key result
Transapical NeoChord mitral valve repair had an 11% 1-year patient failure rate, with CUSUM analysis demonstrating stable performance after 49 procedures.

What is the learning curve and 1-year failure rate of transapical NeoChord mitral valve repair in patients with degenerative mitral valve regurgitation?
Transapical NeoChord mitral valve repair has an initial learning curve requiring approximately 40-49 procedures to achieve stable performance and acceptable 1-year outcomes.
No takes yet. Share an insight, caveat, or question.
CUSUM monitoring may detect performance issues early in NeoChord adoption; leaves open whether it improves outcomes.
Colli et al. (2018) conducted an observational in Degenerative mitral valve regurgitation (n=112). Transapical off-pump mitral valve intervention with neochordae implantation (NeoChord repair) was evaluated on 1-year patient failure based on Mitral Valve Academic Research Consortium criteria. Transapical NeoChord mitral valve repair had an 11% 1-year patient failure rate, with CUSUM analysis demonstrating stable performance after 49 procedures.
