Echocardiographic Assessment of the Mitral Annular Dimensions for Annuloplasty Ring Sizing: A Comparative Clinical Study of Two- and Three-Dimensional Ultrasound
Authors' conclusion
Software-based 3D echocardiographic assessment (4D MVA) of the mitral annulus geometry might provide superior accuracy for predicting appropriate annuloplasty ring size compared with conventional 2D measurements, supporting its role in individualized decision-making.

- Exposure
- 4D MVA vs 2D
- Outcome
- Strongest correlation with annuloplasty ring size
