Abstract Objective: To evaluate left atrial(LA) function in patients with rheumatic mitral stenosis(MS) and sinus rhythm before and after percutaneous balloon mitral valvuloplasty(PBMV) by real time three-dimensional echocardiography(RT-3DE). Methods: Thirty healthy volunteers and thirty patients with MS and sinus rhythm who underwent PBMV were examined by RT-3DE. LA voulme indices including: maximum, minimum, pre-atrial contraction LA volume index(LAVmaxI, LAVminI, LAVpreAI), LA function indices including total atrial, passive atrial, active atrial stroke volume index(TASVI, PASVI, AASVI) and total, passive, active atrial ejection fraction(LAEF, LAEFpassive, LAEFactive) were measured and calculated. Relationships between the changes of LA volume and function indices and the changes of mitral valve area(MVA) and mean mitral gradient(MMG) were analyzed. Results: ①LA volume indices were significantly greater in patients with MS than the controls, and the indices were decreased after PBMV(P<0.05). PASVI, TASVI were significantly greater and AASVI were significantly lower in patients with MS than the controls(P<0.05). PASVI were increased and AASVI were decreased. TASVI was not significantly different from healthy volunteers after PBMV(P<0.05). LAEFpassive, LAEFactive, LAEF were significantly lower in patients with MS than the controls, and the indices were increased after PBMV(P<0.05). ②There were significant correlations between the changes of LA volume and function indices with the changes of MVA and MMG(P<0.05). Conclusion: RT-3DE can evaluate LA function in patients with MS and sinus rhythm before and after PBMV.
