Abstract:
Objective To investigate the assessment of multi-detector spiral CT on the cardiac function after bioprosthetic valve replacement with mitral valve preservation.Methods Thirty-five patients suitable for undergoing bioprosthetic mitral valve replacement in our hospital from May 2012 to February 2014 were randomly divided into 2 groups:group A(experimental group,intraoperative preservation of mitral valve and subvalvular structure during,n=16) and group B (control group,without intraoperative preservation of subvalvular structure of mitral valve,n=19).MDCT before operation and on postoperative 10 d was performed for evaluating the left ventricular function.Results In the comparison of preoperative MDCT,the end diastolic velocity(EDV),end systolic velocity(ESV),ejection fraction(EF) and stroke volume(SV) had no statistical difference between the group A and B.In MDCT results on postoperative 10 d,EDV,ESV and EF in the group A were 113.42±9.22)mL,(38.63±3.40)mL and (51.63±4.71) ％,which in the group B were(113.42 ± 9.22) mL,(38.63 ± 3.40) mL and (51.63 ± 4.71) ％ respectively,the difference was statistically significant(P＜0.05),but SV had no statistical difference between the two groups(P＞0.05).Conclusion The bioprosthetic valve replacement with mitral valve preservation is safe and feasible in technology,moreover effectively protects the postoperative left ventricular function.
