Evaluation of hemodynamics in patients with mitral stenosis after mitral valve replacement by echocardiography
摘要
Abstract
Objective:To investigate echocardiography parameters of patients with mitral stenosis after mitral valve replacement and to provide valuable informations for clinical management and the development of novel valve.Methods:A total of 58 patients who underwent mitral valve replacement from December 2012 to December 2015 were enrolled in this study.They had been followed up with echocardiography 1 year after operation.Left atrial diameter(LA),left ventricular diameter(LV),right atrial diameter(RA),right ven-tricular diameter(RV),left ventricular ejection fraction(LVEF),left ventricular fractional shortening(LVFS),mitral effective orifice ar-ea(EOAmv),peak E velocity of mitral valve(Emv),left atrial area(LAA),left atrial volume(LAV),mitral mean pressure gradient (MPGmv),velocity time integral(VTImv) and pressure half time(PHTmv)had been investigated to evaluate the changes of cardiac structure,function and hemodynamics.Results:Compared with preoperative results,LA,LAA and LAV were significantly lawer then those before operation(P<0.05),but there was no significant difference in LV,RA,RV before and after operation.There was no signif-icant difference in the index of left ventricular function before and after operation.Mitral effective orifice area(EOAmv) was significant-ly increased,while MPGmv,VTImv and PHTmv were significantly decreased (P<0.05).Conclusion:Hemodynamic parameters have been significantly improvedafter mitral valve replacement.关键词
