Design outcomes

Primary

Measure	Time frame
Correlation between the size of annuloplasty ring size and predicted size by using 3D-TEE	—

Secondary

Measure	Time frame
Evaluate whether the discrepancy between the annuloplasty ring size and predicted size by using 3D-TEE affect the postoperative residual mitral regurgitation. Correlation between the size of annuloplasty ring size and predicted size by using 3D-TEE due to the difference of the lesion site (anterior leaflet or posterior leaflet) Complication of transesophageal echocardiography Postoperative complication Postoperative recovery (respiration time, stay in intensive care unit, hospital stay)	—
