Abstract：Objective To explore the difference in left ventricular reverse remodeling(LVRR)between coarctation of aorta(CoA)complicated by bicuspid aortic valve(BAV)and that by tricuspid aortic valve(TAV)after percutaneous intervention.Methods The clinical data on 47 patients undergoing percutaneous balloon dila-tion and stent implantation due to CoA in Fuwai Hospital of Chinese Academy of Medical Sciences from January 2014 to December 2021 were retrospectively analyzed.According to the preoperative imaging data,there were 18 patients with BAVA and 29 with TAV.The results of echocardiography before and one year after the procedure were compared.Results CoA Vmax,CoA PG,LVEDd,LVEDdi,LVM and LVMI were significantly improved in CoA patients one year after percutaneous intervention,and 23.4%of the patients developed left ventricular reverse remodeling.AV Vmax,AV PG and LVEDdi in the patients with BAV were higher than those in the TAV group(P = 0.005 and P = 0.007;P = 0.03),and the rate of left ventricular reverse remodeling in BAV patients was lower than that in TAV patients,but there was no statistical significance.Multivariate analysis did not find any influence factors affecting left ventricular reverse remodeling one year after the procedure.Conclusions Part of the CoA patients develops left ventricular remodeling reversal one year after percutaneous intervention.LVRR in patients with BAV is lower than that in those with TAV,which still needs further clinical research.
