UNASSIGNED: Transcatheter @entity886 (TAVI) is the treatment of choice for inoperable and high-risk @entity1 with severe @entity472 . Our objectives were to elucidate potential differences in clinical outcomes and safety between balloon-expandable versus self-expandable transcatheter heart valves ( @entity5240 ). We performed a retrospective cohort study of all transfemoral TAVI procedures in Ontario, Canada, from 2007 to 2013. @entity1 were categorized into either balloon-expandable or self-expandable @entity5240 groups. The primary outcomes were 30-day and 1-year @entity204 , with secondary outcomes of all-cause readmission. Safety outcomes included @entity548 , permanent pacemaker implantation, need for a second @entity5240 device, postprocedural paravalvular @entity337 , @entity64 , @entity455 , and intensive care unit length of stay. Inverse probability of treatment-weighted regression analyses using a propensity score were used to account for differences in baseline confounders. Our cohort consisted of 714 @entity1 , of whom 397 received a self-expandable @entity5240 , whereas 317 had a balloon-expandable @entity5240 system. There were no differences in @entity204 or all-cause readmission. In terms of safety, the self-expandable group was associated with significantly higher rates of @entity64 (p value <0.05), need for a second @entity5240 device (5.3% vs 2.7%; p value = 0.013), and permanent pacemaker (22.6% vs 8.9%; p value <0.001), whereas the balloon-expandable group had more vascular access site complications (23.1% vs 16.7%; p value = 0.002). Thus, we found similar clinical outcomes of @entity204 or readmission for @entity1 who underwent transfemoral TAVI with either balloon-expandable or self-expandable @entity5240 systems. However, there were important differences in their safety profiles.
