Transcatheter versus Surgical Aortic Valve Replacement in High-risk Patients: A propensity-score matched analysis - 28/05/16
Résumé |
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 <0.001). Unadjusted 30-day mortality was comparable between groups (2/64, 3% vs. 22/669, 3%, P >0.99). The matched analysis revealed comparable 30-day mortality (TAVI: 2/44, 5% vs. sAVR: 2/44, 5%, P > 0.99). New atrial arrhythmia occurred more frequently within the sAVR cohort (TAVI: 1/44, 2% vs. sAVR 18/44, 41%, P <0.001). Complete heart block requiring permanent pacemaker was more frequent amongst the TAVI cohort (TAVI: 10/44, 23% vs. sAVR 2/44, 5%, P=0.039). At two years, survival was comparable between groups (TAVI: 74±1.7 vs. sAVR: 80±0.1%, P=0.65).
Conclusion |
This single centre experience suggests that TAVI is a valuable treatment option for high-risk surgical patients with comparable survival.
