From: Immediate, short-term, and long-term effects of balloon mitral valvuloplasty on the left atrial global longitudinal strain and its correlation to the outcomes in patients with severe rheumatic mitral stenosis

		Pre-procedural	Post-procedural	p value (Sig.)
Function class	Class (I)	0	52 (52.0%)	< 0.01**
