Key result
Surgical AVR resolves severe mechanical hemolytic anemia caused by post-TAVI paravalvular leak.
Why the study?
Severe hemolytic anemia caused by residual paravalvular leak following TAVI is a rare complication that may require surgical intervention.
Case Report (n=1)

Severe hemolytic anemia from paravalvular leak after TAVI is a rare complication that may require surgical aortic valve replacement.
Residual PVL after TAVI may cause severe hemolytic anemia requiring surgical AVR; this case leaves open questions on incidence and prevention.
Objective: We report a rare case of severe hemolytic anemia caused by residual paravalvular leak (PVL) following transcatheter aortic valve implantation (TAVI), which ultimately required surgical aortic valve replacement (AVR).

Kariya et al. (2026) conducted a case report in Hemolytic anemia due to paravalvular leak after TAVI (n=1). Surgical aortic valve replacement was evaluated on Resolution of anemia. Surgical aortic valve replacement successfully resolved severe mechanical hemolytic anemia caused by mild residual paravalvular leak following transcatheter aortic valve implantation.
