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...

Patients with low-flow, low-gradient (LFLG) aortic stenosis (AS) have the highest risk among all AS patients. We investigated the effects of rapid ventricular pacing in patients with LFLG-AS.

Patients with low-flow,...

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...
