Key result
Prosthesis-patient mismatch after aortic valve replacement for aortic stenosis did not significantly affect 10-year overall survival (p=0.345), but resulted in lower left ventricular mass regression.
Why the study?
Does prosthesis-patient mismatch affect long-term survival and left ventricular mass regression in patients undergoing isolated aortic valve replacement for aortic stenosis?
Cohort (n=146)
Does prosthesis-patient mismatch affect long-term survival and left ventricular mass regression in patients undergoing isolated aortic valve replacement for aortic stenosis?
p-value: p=0.345
Prosthesis-patient mismatch after aortic valve replacement for aortic stenosis does not negatively impact 10-year survival, but it does impair the extent of left ventricular mass regression.
No takes yet. Share an insight, caveat, or question.
PPM after AVR does not appear to affect 10-year survival; leaves open its relevance for LV mass regression in observational data.
Kato et al. (2007) conducted a cohort in Aortic stenosis (n=146). Prosthesis-patient mismatch vs. No prosthesis-patient mismatch was evaluated on Overall survival (p=0.345). Prosthesis-patient mismatch after aortic valve replacement for aortic stenosis did not significantly affect 10-year overall survival (p=0.345), but resulted in lower left ventricular mass regression.
