Conclusions Systematic identification of new-onset arrhythmias following TAVI may have considerable impact on subsequent therapeutic management and long-term prognosis in this patient population
Objective To evaluate the prevalence and clinical impact of new-onset arrhythmias in patients following transcatheter aortic valve implantation ( TAVI ) .
Transcatheter versus Surgical Aortic Valve Replacement in High-risk Patients: A propensity-score matched analysis.
BACKGROUND There is limited data from Australia and New Zeal and 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
