Minimally invasive extracorporeal circuits have been introduced to cardiac surgery in an attempt to reduce the negative effects of cardiopulmonary bypass on patient outcome. On the other hand, transcatheter aortic valve replacement (TAVR) provides an excellent option to replace the aortic valve without the need for cardiopulmonary bypass. Several studies have compared TAVR to surgical aortic valve replacement (SAVR) but none have utilized a minimally invasive extracorporeal circuit.

用微创体外循环置换主动脉瓣是否是八岁患者的现代选择？

微创体外回路已被引入心脏外科手术，以试图减少体外循环对患者预后的负面影响。另一方面，经导管主动脉瓣置换术（TAVR）提供了一个很好的选择，无需进行心肺旁路手术即可更换主动脉瓣膜。几项研究已将TAVR与外科主动脉瓣置换术（SAVR）进行了比较，但没有一项研究利用微创体外循环。
