Abstract:
Paravalvular regurgitation remains a frequent finding after transcatheter aortic valve replacement and is associated with unfavorable outcomes if more-than-mild grade. In this case, a patient underwent a third transcatheter aortic valve replacement procedure for worsening symptoms due to severe paravalvular regurgitation. The case underlines the role of preprocedural planning in achieving treatment success.
