    Abstract:
    AIMS: The aim of the study was to investigate the changes in quality of life (QoL) following transcatheter aortic valve implantation (TAVI) up to two years' follow-up. METHODS AND RESULTS: One hundred consecutive patients (46 females, mean age 79.7 ± 6.1 years) with at least two years' follow-up who underwent TAVI in our institution, between November 2007 and September 2009, were enrolled in this study. Peak and mean aortic gradients were 87.8 ± 25.8 mmHg and 53.3 ± 15.4 mmHg, respectively. Mean log EuroSCORE was 27.9 ± 15.9. Patients had multiple comorbidities. All patients underwent a standardised prospective screening pathway, including QoL evaluation with the 36-item short-form health survey (SF-36v2(®)) and the Minnesota Living with Heart Failure Questionnaires (MLHFQ). The scores obtained preoperatively were compared with those obtained at two years' follow-up. An Edwards SAPIEN valve (Edwards Lifesciences, Irvine, CA, USA) was implanted in 67 patients (55 transfemoral and 12 transapical) and a CoreValve (Medtronic, Inc., Minneapolis, MN, USA) was implanted in 33 patients (26 transfemoral and seven transaxillary). Thirty-day mortality was 4%. Actuarial survival was 80.6 ± 4.1%, 72.6 ± 4.7% and 63.2 ± 6.3% at one, two and three years, respectively. Mean SF36-physical improved from 31.9 ± 8.8 to 51.5 ± 9.5 (p<0.0001) and SF36-mental improved from 44.7 ± 11.6 to 49.5 ± 8.6 (p=0.0002). Mean MLHFQ decreased from 41.5 ± 14.5 to 15.9 ± 13.7 (p<0.0001). QoL score changes were not influenced by age or comorbidities. CONCLUSIONS: TAVI in high-risk surgical candidates is associated with favourable short and long-term survival and with improvement of QoL up to two years after the procedure.
