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 ) .
New-onset atrial fibrillation after aortic valve replacement: comparison of transfemoral, transapical, transaortic, and surgical approaches.
OBJECTIVES This study sought to determine the incidence of  new-onset atrial fibrillation ( AF )  associated with different methods of  isolated aortic valve replacement (AVR)-transfemoral ( TF ) , transapical ( TA ) , and transaortic ( TAo ) catheter-based valve replacement and conventional surgical approaches . BACKGROUND The relative incidences of AF associated with the various access routes for AVR have not been well characterized . METHODS In this single-center , retrospective cohort study , we evaluated a total of 231 consecutive patients who underwent AVR for degenerative aortic stenosis ( AS ) between March 2010 and September 2012 . Patients with a history of paroxysmal , persistent , or chronic AF , with bicuspid aortic valves , and patients who died within 48 h after AVR were excluded . A total of 123 patients ( 53 % of total group ) qualified for inclusion . Data on documented episodes of new-onset AF , along with all clinical , echocardiographic , procedural , and 30-day follow-up data , were collated . RESULTS AF occurred in 52 patients ( 42.3 % ) . AF incidence varied according to the procedural method . AF occurred in 60 % of patients who underwent surgical AVR ( SAVR ) , in 53 % after TA-TAVR , in 33 % after TAo-TAVR cases , and 14 % after TF-TAVR . The episodes occurred at a median time interval of 53 ( 25th to 75th percentile , 41 to 87 ) h after completion of the procedure . Procedures without pericardiotomy had an 82 % risk reduction of AF compared with those with pericardiotomy ( adjusted odds ratio : 0.18 ; 95 % confidence interval : 0.05 to 0.59 ) . CONCLUSIONS AF was a common complication of AVR with a cumulative incidence of > 40 % in elderly patients with degenerative AS who underwent either SAVR or TAVR . AF was most common with SAVR and least common with TF-TAVR . Procedures without pericardiotomy were associated with a lower incidence of AF
