Less pronounced reverse left ventricular remodeling in patients with bicuspid aortic stenosis treated with transcatheter aortic valve replacement compared to tricuspid aortic stenosis

To compare reverse left ventricular (LV) remodeling after transcatheter aortic valve replacement (TAVR) between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV). We retrospectively reviewed data of patients with at least two serial echocardiographic follow-ups (1, 3, 6 months and 1 year) post-TAVR. A total of 116 patients were identified. BAV morphology was documented in 67 patients. LV mass index (LVMi) at baseline was not significantly different between the TAV and BAV group (178.0 ± 6.9 vs. 166.3 ± 6.4 g/m 2 , P = 0.14). Reverse LV remodeling was observed in both BAV and TAV patients, but the reduction of LVMi from baseline was significantly more pronounced in TAV patients compared with BAV patients from 6 months post-TAVR (− 56.3 ± 8.1 vs. − 30.0 ± 4.7 g/m 2 , P
