Methods
We prospectively enrolled 93 patients with primary MR from April 2022 to
August 2022. We obtained the baseline characteristics and the following
TTE parameters: mitral valve (MV) velocity-time integral (VTI), left
ventricular outlet (LVOT) diameter (D), LVOT VTI, and mitral valve
annulus (MVA) diameter. The statistical analysis was performed using
SPSS.
