Design outcomes

Primary

Measure	Time frame
For all included patients, echocardiographic measurements will be collected once prior the start of the surgery. The primary endpoints are correlations between the following measurements and the size of the implanted annuloplasty ring: 1. 2D measurements - AP diameter - Intercommissural diameter 2. 3D measurements - AP diameter - AL-PM diameter	—

Secondary

Measure	Time frame
Correlations of additional measurements obtained through a 3D-software with the size of the implanted annuloplasty ring Correlations of additional measurements obtained using 2D echocardiography with the size of the implanted annuloplasty ring Correlations of measurements obtained using 3D echocardiography with subsequent processing in MPR (multiplanar reconstruction) with the size of the implanted annuloplasty ring	—
