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.
