Abstract 15663: Comparison of Health Resources Utilization Before and After Tavi Implantation in Non-Surgical Symptomatic Severe Aortic Stenosis Patients
TAVI improves survival in patients with severe aortic stenosis not eligible for conventional aortic valve replacement (NSAS). However, there is a lack of knowledge regarding the economical costs that TAVI could present for Health Systems, and if these costs are justified. The aim of our study was to describe and to compare health resource utilization before and after TAVI implantation in our institution. We prospectively studied 113 consecutive NSAS patients considered candidate for TAVI. Median age was 81 y (Q1 75- Q3 85), mean Logistic EuroScore 16.8% (range 1.51-78.05). Mean time until TAVI implantation or exitus while in the waiting list was 200 days/patient (median 147 days, Q1 66-Q3 258). Eleven patients died waiting for TAVI. Eighty-six TAVI were implanted. Three TAVI patients died during or immediately after TAVI implantation. Mean clinical follow-up after TAVI was 499 days/patient (median 394 days, Q1 219-Q3 744). After TAVI there were significant decreases in: number of cardiac admissions (163 vs 19; 4,2 per patient-year vs. 0,3; p<0.001), in hospital stay length (1181 days vs 187; 2.87 per patient-month vs. 0.36; p<0.001), in Intensive Care Unit stay length (175 days vs. 49; 0,25 per patient-month vs. 0,08; p=0.004), and in number of outpatient clinical visits (0,433 per patient-year vs. 0.29; p<0.001). There was no significant difference in emergency room visits (44 vs. 20; 1.03 per patient-year vs. 0,33; p=0,179). Patients with NSAS in the waiting list for TAVI show a high rate of morbidity and mortality, and consequently a high health resource utilization that are clearly reduced after TAVI implantation.
