Why the study?
Does the 1-by-1 tensioning sequence improve coaptation area and valve biomechanics compared to the all-together sequence in finite element models of prolapsing mitral valves?
Does the 1-by-1 tensioning sequence improve coaptation area and valve biomechanics compared to the all-together sequence in finite element models of prolapsing mitral valves?
Numerical simulations suggest that a 1-by-1 tensioning sequence for neochords results in biomechanics closer to a healthy mitral valve compared to an all-together approach.

Modeling may reduce neochord-related leaflet complications; leaves open clinical validation before practice change.
