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 ) .
Acute and long-term (2-years) clinical outcomes of the CoreValve 31mm in large aortic annuli: A multicenter study.
INTRODUCTION Little is known about the early and late performance of the 31 mm CoreValve Revalving System ( CRS , Medtronic Inc. , Galway , Irel and ) . Our aim was to compare acute and long-term results of the 31 mm CRS with other valve sizes . METHODS Consecutive patients undergoing transcatheter aortic valve implantation ( TAVI ) with CRS in nine Italian centers were prospect ively included and dichotomized according to prosthesis size in two different groups , as follows : 31 mm and other valve sizes ( i.e. , 23 , 26 , and 29 mm combined ) . End points were defined according to Valve Academic Research Consortium definitions . Propensity score matching was performed . RESULTS In total , 2069 patients ( n=169 [ 8 % ] in the 31 mm group and n=1900 [ 92 % ] in the other valve sizes group ) were included . After propensity matching , the implantation of the 31 mm valve was associated with lower rates of procedural- ( 91.3 % vs. 98.1 % , p=0.030 ) and device-success ( 88.5 % vs. 97.1 % , p=0.016 ) , longer procedural time ( 120 [ 80 - 180 ] min . vs. 90 [ 60 - 120 ] min . , p<0.001 ) , and higher rates of implantation of a second valve ( 10.6 % vs. 2.9 % , respectively , p=0.027 ) . The rates of permanent pacemaker implantation in the 31 mm group were higher but not statistically different from other valve sizes ( 41.7 % vs. 30.9 % , respectively , p=0.149 ) . Significant improvement , without between-group differences , was observed in NYHA functional class . Cardiovascular death was lower in the 31 mm valve group through 2-years ( 3.8 % vs. 13.5 % , respectively , p=0.014 ) . CONCLUSIONS The acute performance of the 31 mm CRS was worse than other valve sizes but no negative impact was observed in long-term outcomes
