Clinical Effect Analysis Of Mitral Insufficiency After Valve Replacement

Objective: From December 2011 to December 2013,57 patients with the diagnosis of rheumatic heart disease complicated by mitral insufficiency underwent mitral valve replacement surgery。To evaluate the long-term clinical effect of mitral valve insufficiency patients by analyzing the hemodynamics of left ventricular system and,the indexes of left atrium and ventricle,in order to better serve the patients.Methods: Retrospectively summarized 217 cases of mitral valve replacement under cardiopulmonary bypass due to rheumatic heart disease mitral insufficiency in our hospital cardiac vascular surgery from December 2011 to December 2013,and selected 57 cases of perfect auxiliary examination before and after surgery.According to ventricular end diastolic volume of the preoperative echocardiogram,the ventricle was divided into two groups: giant left ventricle(left ventricular end-diastolic diameter LVEDD ≥ 70mm)and non-giant left ventricle group.The left ventricular diastolic diameter(LVEDD),left ventricular end-contraction diameter(LVESD),left atrium anterior and posterior diameter(LAD),EF and FS were analyzed by SPSS 21.Results: The long-term follow-up results of two groups after mitral valve replacement were compared with preoperative,LVEDD,LVESD,LAD and cardiac EF value were better than preoperative,P < 0.05,the difference was statistically significant,but the changes of FS in heart after valve replacement were not significantly changed(P > 0.05).The comparison between groups,LVEDD,LVESD and LAD of the huge left ventricular group Compared with the non giant left ventricle group,it decreased significantly(P < 0.05);LVEF increased significantly in the non giant left ventricle group(P < 0.05).Conclusion: The left ventricular diastolic diameter,left ventricular systolic end diameter,left atrial anterior and posterior diameter were significantly reduced after mitral valve replacement under cardiopulmonary bypass,especially in giant left ventricle group.The long term left ventricular function was significantly improved in both groups,especially in the non-giant left ventricle group.
