Abstract

Scarce data are available on the impact of age on transcatheter aortic valve implantation (TAVI) outcomes. We therefore, analyzed 1,845 consecutive patients from 9 Italian centers who underwent TAVI with the Corevalve Revalving System from September 2007 to March 2014; patients were dichotomized according to their age in the date of the procedure, as follows: 75 to 85 years old and >85 years old. End points were defined according to Valve Academic Research Consortium definitions. In-hospital, 30-day, and 1-year clinical and echocardiographic data were available for 100% of the patients included. Propensity matching was performed. Procedural success rates were high (>94%) and comparable between groups. Although worse baseline renal function was observed in the older group, the incidence of acute kidney injury after procedure was comparable (17.1% and 17.4%, respectively for the 75- to 85- and >85-year-old group, p = 0.877); importantly, >99% of acute kidney injury episodes in both groups were grades 1 and 2. Procedural complications rates were low without between-group differences. In-hospital death (3.7% and 4.6%, p = 0.379) and stroke/transient ischemic attack (1.9% and 1.9%, respectively, p = 0.960) were comparable. The 1-year death rates were 14.9% and 17.2% (p = 0.197) in the 75- to 85- and >85-year-old group, respectively. Cardiovascular death was observed in 7.8% and 7% (p = 0.542), while stroke/transient ischemic attack was demonstrated in 5.2% and 4.4% (p = 0.496), respectively. Results were sustained after propensity matching. In conclusion, advanced age did not negatively impact the outcomes of TAVI through 1-year after procedure.
