Key result
Prosthesis-patient size, measured by indexed orifice area or standardized orifice size, was not associated with functional recovery after aortic valve replacement (P=0.94 and P=0.96, respectively).
Why the study?
Does prosthesis-patient size mismatch impact functional recovery after aortic valve replacement?
Cohort (n=1,108)
Does prosthesis-patient size mismatch impact functional recovery after aortic valve replacement?
p-value: p=0.94
Prosthesis-patient size mismatch does not significantly impact early functional recovery after aortic valve replacement, which is instead influenced by factors like age, sex, and comorbidities.
No takes yet. Share an insight, caveat, or question.
Mismatch was not linked to functional recovery after AVR; leaves open whether size optimization affects longer-term outcomes.
Koch et al. (2005) conducted a cohort in Aortic Valve Replacement (n=1,108). Prosthesis-patient size was evaluated on Postoperative functional recovery measured by the Duke Activity Status Index (DASI) (p=0.94). Prosthesis-patient size, measured by indexed orifice area or standardized orifice size, was not associated with functional recovery after aortic valve replacement (P=0.94 and P=0.96, respectively).
