Key result
Severe patient-prosthesis mismatch post-AVR is linked to lower physical scores but not worse long-term survival.
Why the study?
Does severe patient-prosthesis mismatch reduce long-term survival or quality of life in patients following isolated stented biological AVR?

No
Does severe patient-prosthesis mismatch reduce long-term survival or quality of life in patients following isolated stented biological AVR?
p-value: p=0.014 for PCS score; 0.75 for survival
Severe patient-prosthesis mismatch after biological AVR negatively impacts physical quality of life but does not significantly affect long-term survival.
May impair physical QoL after AVR; leaves open survival effects in larger prospective cohorts.
Background The impact of patient-prosthesis mismatch (PPM) after aortic valve replacement (AVR) on long-term survival and quality of life (QoL) remains controversial. The objective of this study was to evaluate the impact of PPM on long-term survival and QoL in a large cohort of patients treated with isolated stented biological AVR in a single-center experience. Methods We analyzed data of 632 consecutive patients following isolated stented biological AVR between 2007 and 2012 at our institution. We evaluated the QoL (393 evaluable patients) using the Short Form 12-item Health Survey (SF-12) questionnaire via telephone call and the impact of PPM on long-term survival (533 evaluable patients) by Kaplan–Meier's estimate. Results Severe PPM (<0.65 cm2/m2) had a negative impact on physical component summary (PCS) score (SF-12) compared with patients with moderate or no PPM (p = 0.014), while the mental component summary (MCS) score (SF-12) was not affected by the degree of PPM (p = 0.133). Long-term survival was not different among the three different PPM groups investigated (p = 0.75). Conclusion Severity of PPM demonstrated no influence on long-term survival and MCS score (SF-12), but it was associated with a lower PCS score (SF-12) in patients with severe PPM.

Hoffmann et al. (2018) conducted a cohort in Aortic Valve Replacement (n=632). Severe patient-prosthesis mismatch (<0.65 cm2/m2) vs. Moderate or no patient-prosthesis mismatch was evaluated on Physical component summary (PCS) score and long-term survival (p=0.014 for PCS score; 0.75 for survival). Severe patient-prosthesis mismatch after aortic valve replacement was associated with a lower physical component summary score (P=0.014) but did not affect long-term survival (P=0.75).
