Popis: Transcatheter Aortic Valve Replacement (TAVR) is considered the treatment in patients older or at high or intermediate risk. Results form contemporary randomized trials in low-risk patients will likely broaden the indication of TAVR, but the data regarding long-term are limited by older population. The aim of this study was to evaluate the survival and the factors predicting mortality after TAVR in according to age. Methods From April 2008 to December 2019, the self-expandable and balloon-expandable prostheses were was implanted in 765 patients with symptomatic severe aortic stenosis with deemed high risk on base to age, Results The mean age in patients 0.001, respectively In-hospital mortality was 4% vs. 3.4%, p=0.404, and the rate of acute complications was 19.6 vs. 16.5%, p=0.168. The late mortality (beyond 30 days) was 36.9 vs. 35.2%, p=0.352. When compared in both groups, there were no differences for the presence of threatening bleeding 3.4% vs. 3.2% (HR = 1.028 [IC95% 0.722–1.463], p=0.516), myocardial infarction 4% vs. 2.5% (HR = 1.263 [IC95% 0.814–1.960], p=0.167), stroke 8% vs. 9.1% (HR = 1.149 [IC95% 0.686–1.925], p=0.347) and acute kidney innjury 14.1% vs. 19.1% (HR=0.1.14 [IC95% 0.969–2.141], p=0.071) and there was difference in between groups in hospitalizations for heart failure 14.6% vs. 7.9% (HR = 1.398 [IC95% 1.075–1.817], p=0.008 Survival at 1, 3, and 5were similar in both groups (88% vs. 89.5%, 73.3 vs. 78.2%, 58.8 vs. 62.6%, log Rank 0.992, p=0.319), respectively, after a mean follow-up of 42.3±27 months. The main predictors of cumulative mortality in young patients were: Charlson index [HR 1.18 (95% CI 1.06–1.30), p=0.001], Acute Kidney Injury [HR 2.21 (95% CI 1.42–3.47), p=0.001], Left ventricular ejection fraction [HR 1.02 (95% CI 1.009–1.035), p=0,001], and protective factor was a higher Karnosfky index [HR 0.98 (95% CI 0.97–0.99) p=0.006]. And in older patients were: Frailty [HR 1.67 (95% CI 1.13–2.47), p=0.010], COPD [HR 2.09 (95% CI 1.41–2.91), p=0,001], Stroke [HR 3.01 (95% CI 1.54–5.89), p=0.001] Charlson index [HR 1.14 (95% CI 1.02–1.27), p=0.015], Acute Kidney Injury [HR 1.57 (95% CI 1.06–2.32), p=0.001. Conclusions TAVR is associated with low complications rate in young and older patients. Survival during follow-up was similar in both groups, but the predictive factors of mortality differ, with greater impact on the comorbidtiy in the elderly patients Funding Acknowledgement Type of funding sources: None.
