Transcatheter aortic valve implantation after aortic valve neocuspidization using autologous pericardium: a case report.

ABSTRACT: Background:Aortic valve neocuspidization (AVNeo), a novel surgical procedure used in the treatment of aortic valve diseases, including aortic stenosis (AS), involves the replacement of three aortic valve cusps by glutaraldehyde-treated autologous pericardium. Although reoperation risk is low, no case report on the deterioration of the AVNeo has yet been published. Case summary:An 80-year-old woman who underwent AVNeo for severe degenerative tricuspid AS 6?years previously complained of shortness of breath. Echocardiographic assessment revealed the reconstructed aortic valve leaflet was elongated, thickened, and marginally calcified resulting in recurrent severe AS. Transcatheter aortic valve implantation using balloon-expandable transcatheter heart valve was successfully performed. Discussion:To our knowledge, this is the first case report regarding the structural deterioration of the AVNeo resulting in restenosis 6?years after the first surgery. Transcatheter aortic valve implantation is possibly a suitable approach for post-procedural recurrence after AVNeo to avoid redo open-heart surgery which would be of prohibitive risk especially in an elderly population.
