Table 2 Transthoracic echocardiographic and 2D STE findings before and after balloon mitral valvotomy

From: Strain imaging to assess early effects of successful percutaneous balloon mitral valvotomy on left atrium mechanics

 Pre-BMVPost-BMVp value
MVA (cm2)1.045 ± 0.171.94 ± 0.22< 0.001
MMG (mmHg)16.94 ± 6.628.19 ± 4.01< 0.001
