This study compares both the feasibility and outcomes of “off-label” transcatheter aortic valve replacement (TAVR) patients (n=156) with a standard “on-label” TAVR population (n=435) at a single institution.

This study compares both the...

We aimed to develop and validate an effective prediction model for 1-year mortality risk in elective transfemoral transcatheter aortic valve replacement (TAVR), ie, the TAVR-Risk (TARI) model.

We aimed to develop and validate...

Currently, it is unclear whether transcatheter aortic valve implantation (TAVI) without predilation (direct TAVI; d-TAVI) or with preimplantation balloon valvuloplasty (b-TAVI) provides similar clinical safety and efficacy. Therefore, we...
