Comparison of Outcomes of Transfemoral Aortic Valve Implantation in Patients <90 With Those >90 Years of Age

In patients who underwent transcatheter aortic valve implantation (TAVI), postoperative mortality risk is commonly assessed with risk scores such as the Society of Thoracic Surgeons—Postoperative Risk of Mortality (STS-PROM) and EuroSCORE II, in which age plays a dominant role. However, we reason that in the naturally selected oldest-old patients (nonagenarians), this may not be completely justified and that therefore age should play a minor role in decision-making. The objective of this study was to compare procedural outcome and mid-term mortality of transfemoral (TF)-TAVI patients aged ≥90 years with patients aged <90 years. In this single-center analysis of 599 prospectively acquired consecutive TF-TAVI patients between 2009 and 2017, we compared patients aged ≥90 (i.e., nonagenarians, n = 47) with patients aged <90 years (n = 552), using Kaplan-Meyer analysis and multivariate logistic regression. In the nonagenarians, we found more aortic regurgitation, moderate to severe paravalvular leakage, strokes and vascular complications, and less device success and bleeding complications compared with patients <90 years. Both groups showed similar symptomatic improvement. The predicted (STS-PROM) and actual procedural mortality were 8.033% and 2.1% (3.8×) and 4.868% and 1.8% (2.7×) for the nonagenarians and controls, respectively. Survival was not statistically different at the 1-, 2-, 3-, 4-, and 5-year mark. In conclusion, nonagenarians had similar symptomatic improvement and acceptable procedural outcome and mid-term survival to TF-TAVI patients aged <90 years. Thus, age is not a risk factor in predicting postoperative outcome and mortality and therefore should not be a reason to deny the oldest-old patient transfemoral TAVI.
