Abstract

Background There is limited data from Australia and New Zealand comparing transcatheter aortic valve implantation (TAVI) with conventional surgical aortic valve replacement (sAVR). Methods Between 2009 and 2015, 64 patients underwent TAVI and 669 underwent sAVR at a single centre. Patients’ peri-operative details were analysed and compared between groups. Propensity-score matching was performed for risk adjustment. Results Patients receiving TAVI were older (mean age in years TAVI: 83.9±4.6 vs. sAVR: 71±9.9, P < 0.001), and were more likely to be female (TAVI: 67%, 43/64, vs. sAVR: 32%, 217/669, P 0.99). The matched analysis revealed comparable 30-day mortality (TAVI: 2/44, 5% vs. sAVR: 2/44..
