Analysis of the Feasibility of Strain Rate Imaging Combined with Tissue Doppler Imaging in the Assessment of Left Atrial Function of Patients with Rheumatic Mitral Stenosis
Abstract：[Objective]To explore the feasibility of strain rate imaging(SRI)combined with tissue Doppler imaging(TDI)in the assessment of left atrial function in patients with rheumatic mitral stenosis.[Methods]A total of 50 patients with rheumatic mitral stenosis were chosen and divided into sinus group and atrial fibrilla-tion group with 25 patients in each group.Other 25 healthy subjects were selected as control group.TDI was used to measure in the velocity of mitral ring in atrioventricular j unction area and lateral wall at apical four-chamber view(S for ventricular systole,E for ventricular diastole and A for atrial systole).SRI was used to measure ventricular systolic strain rate(Ssr),early ventricular diastolic strain rate(Esr)and atrial systolic strain rate(Asr)in interatrial septum and left atrium wall.[Results]There was significant difference in TDI S, E and A peak values between sinus or atrial fibrillation groups and control group(P<0.05).There was sig-nificant differences in S and E values of mitral ring side wall and S value of mitral ring interval side between at-rial fibrillation group and sinus group(P<0.05).There was significant difference in Ssr,Esr and Asr at each sampling point between sinus or atrial fibrillation groups and control group(P<0.05).There was significant difference in Ssr at each sampling point and Esr of atrial interval top between atrial fibrillation group and sinus group(P<0.05).[Conclusion]The systolic and diastolic function of left atrial in patients with rheumatic mi-tral stenosis are significantly decreased.SRI and TDI technology can be used to assess the left atrial function in patients with rheumatic mitral stenosis.
