【摘要】 目的 探讨超声心动图在主动脉瓣自体心包重建术中的应用价值。方法 选择2017年9月至2019年12月收治的25例行主动脉瓣自体心包重建术的患者，术前用超声心动图准确测量主动脉瓣环、窦管交界处内径，术前术后观察主动脉瓣跨瓣压、主动脉瓣跨瓣流速、主动脉瓣反流、左心室大小情况。结果 自体心包重建术后1周～1年内随访，主动脉瓣狭窄得到明显改善(P<0.05),左室舒张末径较术前缩小(P<0.05),跨瓣血流最大速度及跨瓣压差下降至正常范围(P<0.05),瓣口反流减少。结论 超声心动图在主动脉瓣自体心包重建术中有着十分重要的作用，尤其对术前诊断、术中监测及术后疗效评估具有重要意义。更多还原

【Abstract】 Objective To evaluate the value of echocardiography in aortic valve neocuspidization(Avneo) with autologous pericardium. Methods 25 patients who underwent Avneo with autologous pericardium from September 2017 to December 2019 were selected. The diameter of aortic annulus and sinus junction was accurately measured by echocardiography before operation, and aortic valve transvalvular pressure, aortic valve transvalvular velocity, aortic regurgitation and left ventricular dimension were observed before and after operation. Results Follow-up within 1 week to 1 year after Avneo with autologous pericardium showed that aortic stenosis was significantly improved(P<0.05), left ventricular end diastolic diameter was smaller than that before operation(P<0.05), the maximum transvalvular blood flow velocity and transvalvular pressure gradient decreased to normal range(P<0.05), and valve orifice reflux decreased. Conclusion Echocardiography plays an important role in Avneo with autologous pericardium, especially in preoperative diagnosis, intraoperative monitoring and postoperative efficacy evaluation.更多还原
