Data collection:
All 38 consecutive patients underwent successful isolated or combined
RD-AVR between May 2019 and April 2020 in the Department of Cardiac
Surgery at the Juntendo University Hospital. The institutional review
board approved this registry, and patients signed informed consent
preoperatively. The comprehensive safety and effectiveness of RD-AVR
were assessed. These data included preoperative native valve function,
postoperative structural/non-structural valve dysfunction, and
hemodynamic valve performance on TTE and electrocardiography-gated
3D-CT.
The primary outcome was hospital mortality and short-term results after
a one-year follow-up. Secondary outcomes relating to prosthetic valve
function, especially PVL, were analyzed. Subset analyses were performed
to determine the relationship between new technical methods and
outcomes.
