Key result
Mitral valve repair significantly increased the coaptation area index measured by 3D TEE from 9.71% preoperatively to 36.24% postoperatively (P<0.05).
Why the study?
Can 2D and 3D transesophageal echocardiography accurately assess mitral valve coaptation before and after mitral valve repair?
Population
48 patients undergoing mitral valve repair for mitral regurgitation, mean age 52.23±13.31 years, 54.17% male.

2D CLI provides a feasible intraoperative alternative to 3D CAI for coaptation assessment; leaves open whether these metrics improve MV repair durability.
Observational (n=48)
Can 2D and 3D transesophageal echocardiography accurately assess mitral valve coaptation before and after mitral valve repair?
Absolute Event Rate: 36.24% vs 9.71%
p-value: p=<0.05
Both 2D and 3D TEE can effectively assess mitral valve coaptation before and after repair, with 2D CLI serving as a simpler alternative to 3D CAI.
Guo et al. (2018) conducted an observational in Mitral regurgitation (n=48). Mitral valve repair vs. Preoperative baseline was evaluated on Coaptation area index (CAI) (p=<0.05). Mitral valve repair significantly increased the coaptation area index measured by 3D TEE from 9.71% preoperatively to 36.24% postoperatively (P<0.05).
