在不久的将来，经皮主动脉置换可能对于外科手术中有高风险的低压力阶差、低射血分数的主动脉狭窄患者是个有价值的选择。

In the near future, percutaneous AVR could be a valuable alternative for surgical high-risk patients with low-gradient, low ejection fraction AS.

此外，随访期左室射血分数正常，术后主动脉瓣功能几无影响。

In addition, left ventricular ejection fraction remained normal and there was minimal impact on aortic valve function after TEVAR.
