Is Patient-Prosthesis Mismatch a Perioperative Predictor of Long-Term Mortality After Aortic Valve Replacement?

Abstract OBJECTIVES This study sought to evaluate the impact of patient–prosthesis mismatch (PPM) on the risk of perioperative, early-, mid- and long-term mortality rates after surgical aortic valve replacement. METHODS Databases were searched for studies published until March 2018. The main outcomes of interest were perioperative mortality, 1-year mortality, 5-year mortality and 10-year mortality. RESULTS The search yielded 3761 studies for inclusion. Of these, 70 articles were analysed, and their data were extracted. The total number of patients included was 108 182 who underwent surgical aortic valve replacement. The incidence of PPM after surgical aortic valve replacement was 53.7% (58 116 with PPM and 50 066 without PPM). Perioperative mortality [odds ratio (OR) 1.491, 95% confidence interval (CI) 1.302–1.707; P < 0.001], 1-year mortality (OR 1.465, 95% CI 1.277–1.681; P < 0.001), 5-year mortality (OR 1.358, 95% CI 1.218–1.515; P < 0.001) and 10-year mortality (OR 1.534, 95% CI 1.290–1.825; P < 0.001) were increased in patients with PPM. Both severe PPM and moderate PPM were associated with increased risk of perioperative mortality, 1-year mortality, 5-year mortality and 10-year mortality when analysed together and separately, although we observed a higher risk in the group with severe PPM. CONCLUSIONS Moderate/severe PPM increases perioperative, early-, mid- and long-term mortality rates proportionally to its severity. The findings of this study support the implementation of surgical strategies to prevent PPM in order to decrease mortality rates.

Long Term Mortality

Introduction: Mortality following Transcatheter aortic valve replacement (TAVR) has been reported up to 5 years. However, mortality after 5 years remains unclear. Hypothesis: We aim to determine the mortality in patients undergoing TAVR >5 years follow up. Methods: From our institution’s prospectively collected TAVR database we analyzed all patients undergoing TAVR to a maximum follow up of 8 years. We divided our population into transapical TAVR (TA-TAVR) and transfemoral TAVR (TF-TAVR) groups. A Kaplan-Meier survival analysis was conducted. Results: A total of 511 patients who underwent TAVR were included in the analysis. Patients undergoing TA-TAVR had higher rates of peripheral vascular disease compared with TF-TAVR (56% vs 29%, p<0.001) and Society of Thoracic Surgeons Score (10.9 ± 4 vs 9.2 ± 4, p<0.001). TA-TAVR was associated with higher mortality at 1 year (32% vs 21%, p=0.01). However, there was no significant difference in very-long term mortality of patients undergoing TA-TAVR vs TF-TAVR (Figure). Conclusions: Long-term mortality following TAVR surpasses 50%. While in the first 2 years TA-TAVR is associated with higher mortality rates after three years the survival rates are similar in both approaches.
