Aim：We aimed to clarify the association between the preoperative 6-min walk distance （6MWD） and rehospitalization within one year in patients undergoing transcatheter aortic valve implan-tation （TAVI）.
Methods：The analysis target was 356 patients who underwent elective transfemoral approach TAVI （TF-TAVI） between May 2018 and December 2020. The cut-off value predicting readmis-sion was calculated in order to compare the readmission rate. Additionally, three models were created by a multivariate analysis in order to examine the association between readmission and preoperative 6MWD.
Results：The preoperative 6MWD cut-off value predicting readmission was set for 168 m and the re-admission rate increased significantly in the group of less than 168 m. Even after adjusting for each factor, preoperative 6MWD was still extracted as a factor predicting readmission.
Conclusion：Preoperative 6MWD is associated with readmission within 1 year after TAVI.
