Why the study?
Does TAVR compared to SAVR reduce prosthesis-patient mismatch and affect clinical outcomes in intermediate- and low-risk patients with severe aortic valve stenosis?
Does TAVR compared to SAVR reduce prosthesis-patient mismatch and affect clinical outcomes in intermediate- and low-risk patients with severe aortic valve stenosis?
TAVR is associated with a lower incidence and severity of prosthesis-patient mismatch compared to SAVR, though severe PPM did not significantly impact 2-year clinical outcomes in this intermediate- and low-risk cohort.
Answers are grounded in this paper and cite their sources.
TAVR reduces PPM incidence and severity versus SAVR without affecting 2-year outcomes; extends evidence favoring TAVR in lower-risk aortic stenosis.
The incidence of PPM was lower and less severe after TAVR compared with SAVR in intermediate- and low-risk patients with severe AVS. There were no significant differences in MACCE, cardiac-related hospitalizations or NYHA class after 2 years for patients with versus those without severe PPM.
