title: Transaortic valve implantation with the direct flow medical valve in an emergency situation of post-valvuloplasty severe aortic regurgitation.
abstract: New technology advances in transcatheter aortic valve implantation (TAVI) promise to improve outcomes and usability. The next generation Direct Flow Medical (DFM) valve is a non metallic, repositionable and retrievable bioprosthesis with a flexible system that provides an optimal circumferential seal. We report a case of TAVI complicated by massive aortic regurgitation after balloon aortic predilation. This case demonstrates that the design and delivery mode of the DFM valve is advantageous during this emergency situation.
