Conclusions RT-3DE provides a fast， convenient， non-invasive technique to evaluate global and regional right ventricular volume and function in patients with MS. Regional right ventricular systolic function can be affected by tricuspid regurgitation.
结论 RT-3DE可以定量评价MS患者右心室整体及局部容积与收缩功能。 三尖瓣反流程度影响右心室整体及局部收缩功能。
