Successful treatment by transcatheter aortic valve implantation of severe aortic regurgitation in a patient with ascending aorta prosthesis

Abstract

Severe aortic regurgitation (AR), when intervention is required, is managed by surgical aortic valve replacement (SAVR). Recently, transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) has shown non-inferiority to SAVR and superiority to medical management. TAVR could be a valid "off label" option to treat severe AR for patients unsuitable for SAVR due to their high surgical risk. Among aortic pathologies leading to severe AR, those involving the aortic root are considered as high risk procedures and thus prohibit TAVR. For these reasons TAVR is not an option for severe AR due to concomitant aortic root dilatation and degeneration. We report a successful case of TAVR for severe AR due to dilatation of degenerated tract of aortic root.
