Objective: No appropriate guidelines concerning perioperative management of transcatheter aortic valve implantation (TAVI) exist for patients with aortic valve stenosis (AS) and concomitant pulmonary hypertension. Peak tricuspid regurgitation velocity (PTRV) has been estimated to be a non-invasive representation of pulmonary artery pressure.

Objective: Only a few reports have detailed the early- to mid-term outcomes of transcatheter aortic valve replacement (TAVR), especially in patients with small body size. This study aimed to evaluate the early- and mid-term outcomes of redo-TAVR in Japanese patients. Methods: This was a retrospective, non-randomized, single-center study. In all 16 consecutive cases (15 patients) who underwent redo-TAVR (excluding redo-TAVR because of intraoperative bailout) were enrolled in this study.
