【摘要】：目的研究多层螺旋CT(MDCT)对保留二尖瓣心脏生物瓣膜替换术后心功能的评价。方法选择2012年5月到2014年2月到该院就诊的适合二尖瓣心脏生物瓣膜替换术的患者共35例,将其分为两组,A组术中保留二尖瓣全瓣及瓣下结构,B组术中不保留二尖瓣瓣下结构。术前,术后10d行MDCT检查,评价左心室功能。结果两组病例术前MDCT对比,A组和B组左心室舒张末期容积(EDV)、左心室收缩末期容积(ESV)、射血分数(EF)、每搏输出量(SV)比较差异无统计学意义(P0.05)。A组术后10dMDCT的结果 EDV、ESV、EF分别为(106.25±8.83)mL、(35.75±4.37)mL、(54.48±4.23)%,B组分别为(113.42±9.22)mL、(38.63±3.40)mL、(51.63±4.71)%,两组比较差异均有统计学意义(P0.05),而两组间SV比较差异无统计学意义(P0.05)。结论保留二尖瓣全瓣的心脏生物瓣膜替换术,技术安全可行,且有效地保护了心脏术后的左心室功能。
[Abstract]:Objective to evaluate the effect of multislice spiral CT (MDCT) on cardiac function after mitral valve replacement. Methods from May 2012 to February 2014, 35 patients who were suitable for mitral valve replacement were selected and divided into two groups: group A, preserving the whole mitral valve and subvalvular structure during operation, and group B did not preserve the subvalvular structure of mitral valve. The left ventricular function was evaluated by MDCT before and 10 days after operation. Results there was no significant difference in left ventricular end-diastolic volume (EDV), left ventricular end-systolic volume (ESV), ejection fraction (EF) and stroke output (SV) between group A and group B (P0.05). (106.25 卤8.83) mL, (35.75 卤4.37) mL, (54.48 卤4.23) M / L were (113.42 卤9.22) mL, (38.63 卤3.40) mL, (51.63 卤4.71) mL, respectively. There was significant difference between the two groups (P0.05), but there was no significant difference in SV between the two groups (P0.05). Conclusion it is safe and feasible to preserve the whole mitral valve and protect the left ventricular function after cardiac surgery.
