Abstract
BACKGROUND: Studies comparing transcatheter and surgical aortic valve replacement (TAVR and SAVR) for patients with trileaflet aortic stenosis (AS) have found similar or larger effective orifice area (EOA) for TAVR prostheses. To our knowledge, no studies have compared EOA in patients undergoing TAVR versus SAVR for bicuspid AS.
METHODS: We retrospectively compared prosthetic valvular sizing and predicted EOA for patients with bicuspid AS undergoing TAVR or SAVR at our institution between January 1, 2016, and December 31, 2021. We excluded patients undergoing procedures for indications other than AS and those without a pre-procedural gated Chest CT. Comparisons included demographics, comorbidities, annular size, prosthetic valve size, predicted EOA and prosthesis-patient mismatch (PPM) for TAVR (N = 78) and SAVR (N = 74) cohorts.
RESULTS: TAVR patients had smaller pre-procedural annular area (501.7 mm
CONCLUSIONS: For bicuspid AS patients undergoing aortic valve replacement, TAVR achieves similar predicted EOA to SAVR. These data support the use of TAVR in selected patients with bicuspid AS and can inform heart team discussions.
