应用二维超声心动图对48例先天性心脏病患者手术前后测定其左室收缩期圆周指数及右室身血分数,并经心导管或术中测压,旨在探讨跨室间隔压力比与左室收缩期圆周指数或右室射血分数的相关性,评价手术疗效。结果示:术后跨室间隔压力比显著降低(p<0.001),上述两项指标明显改善(p<0.001),而且与跨室间隔压力比呈显著负相关线性意义(r=-0.88,-0.82,p<0.001)。结论:二维超声心动图可作为估测跨室间隔压力比,评价手术疗效的可靠方法之一。
Two-dimensional echocardiography was used to measure the left ventricular systolic circulatory index and right ventricular fractional blood flow in 48 patients with congenital heart disease before and after surgery. The cardiac catheter or intraoperative pressure measurement was used to investigate the relationship between transseptal pressure ratio and Left ventricular systolic circumferential index or right ventricular ejection fraction correlation evaluation of surgical efficacy. The results showed that the postoperative interventricular septum pressure ratio was significantly lower (p <0.001), the two indexes were significantly improved (p <0.001), and negatively correlated with interventricular septal pressure ratio (r = -0.88, - 0.82, p <0.001). Conclusion: Two-dimensional echocardiography can be used as a reliable method to evaluate the efficacy of transseptal septal pressure.
