Commissural misalignment of biological valve and autologous valve during transcatheter aortic valve replacement may affect the filling of coronary artery, reduce the feasibility of redo-aortic valve intervention and damage the valve function, which will adversely affect long-term prognosis of patients. Some studies have obtained achievement by changing the axial direction of valve and using individualized computer simulation technology to improve the alignment technology. However, there are still many unknown problems about the impact of commissural misalignment on patients, and accurate commissural alignment techniques still need to be further explored. This article systematically expounds the possible impact of commissural misalignment between biological valve and autologous valve in transcatheter aortic valve replacement, possibly effective accurate commissural alignment techniques and related research progress.
