RESUMEN

Objective To analyze the therapeutic effect of emergency surgery in the treatment of severe valvular heart disease and its influence on heart function.Methods 87 cases with severe valvular heart disease were selected,and they were given emergency surgical treatment.Before and after treatment,the cardiac function index[end -diastolic volume (EDV),end-systolic volume (ESV),left ventricular end systolic volume index (LVESVI),left ventricular end-diastolic volume index (LVEDVI),left ventricular ejection fraction (LVEF)],postoperative complications and survival rate were compared.Results After treatment,the EDV [(125.78 ± 31.67) mL],ESV [(71.30 ± 16.58) mL] and LVESVI [(50.39 ± 13.30) mL/m2],LVEDVI [(88.74 ± 13.51) mL/m2],LVEF [(51.48 ± 12.73) ％] were better than those before treatment [(116.48 ± 28.94) mL,(63.26 ± 15.47) mL,(33.27 ± 8.54) mL/m2,(64.47 ± 12.69)mL/m2,(47.53 ± 11.20)％],the differences were statistically significant (t =2.022,2.022,3.307,12.213,2.173,all P ＜ 0.05).The incidence rate of complications was 24.14％ (21/87),included arrhythmia in 4 cases,low cardiac output syndrome in 8 cases,acute renal failure in 9 cases.Postoperative 1 year,2 years,the survival rates were 91.95％ (80/87),85.06％ (74/87),respectively.Conclusion Emergency surgical treatment for severe valvular heart disease can effectively improve cardiac function index,improve the survival rate.
