Key result
Classic resect and newer respect strategies for degenerative mitral valve repair show comparable short-term outcomes.
Why the study?
Mitral valve repair is the gold standard for mitral regurgitation, but the optimal repair technique remains debated.
Does the 'respect' strategy compared to the 'resect' strategy yield different short-term outcomes in patients undergoing isolated mitral valve repair for degenerative mitral disease?
Cohort
Yes
Does the 'respect' strategy compared to the 'resect' strategy yield different short-term outcomes in patients undergoing isolated mitral valve repair for degenerative mitral disease?
Both 'resect' and 'respect' strategies for mitral valve repair show comparable short-term outcomes, suggesting both approaches are equivocal.
Supports either resect or respect approach short-term; leaves open long-term durability and randomized confirmation.
Objective: Mitral valve repair is the gold standard for treatment of mitral regurgitation, but the optimal technique remains debated. By using a regional collaborative, we sought to determine the change in repair technique over time. Methods: We identified all patients undergoing isolated mitral valve repair from 2012 to 2022 for degenerative mitral disease. Those with endocarditis, transcatheter repair, or tricuspid intervention were excluded. Continuous variables were analyzed via Wilcoxon rank sum, and categorical variables were analyzed via chi-square testing. Results: < .001) were most predictive of no resection repair. Conclusions: Despite minor differences in operative times, statewide over the past decade there remains a diverse mix of both classic "resect" and newer "respect" strategies with comparable short-term outcomes and no major timewise trends. These data may suggest that both approaches are equivocal.

Wisniewski et al. (2024) conducted a cohort in Degenerative mitral disease. Mitral valve repair ('respect' strategy) vs. Mitral valve repair ('resect' strategy) was evaluated on Short-term outcomes and change in repair technique over time. Classic 'resect' and newer 'respect' strategies for degenerative mitral valve repair demonstrated comparable short-term outcomes with no major timewise trends over a 10-year period.
