Figure 4 | TAVI for bicuspid aortic valve disease. a | Anatomy of the bicuspid aortic valve (BAV). Type I BAV involves fusion of the right coronary cusp (RCC) and left coronary cusp (LCC), creating a fused left–right cusp (LRC). Type II BAV involves fusion of the RCC and noncoronary cusp (NCC) to create a fused right–noncoronary cusp (RNC). Type III BAV involves fusion of the LCC and NCC to create fused left–noncoronary cusp (LNC). b | Kaplan–Meier curve showing all-cause mortality in propensity-score matched patients with either bicuspid or tricuspid aortic stenosis (AS) following transcatheter aortic valve implantation (TAVI) with a first-generation transcatheter heart valve.
