Answer

In a retrospective study (2007-2013) of data from 714 Canadian patients with severe aortic stenosis who underwent transfemoral TAVR to evaluate outcomes of balloon-expandable (n = 317) versus self-expandable (n = 397) transcatheter heart valves, investigators found no difference in mortality or all-cause readmission rates between the two groups. [44] However, the safety profile revealed patients in the balloon-expandable group had higher incidences of complications with vascular access sites, compared with those in the self-expandable group who were significantly more likely to suffer an inhospital stroke and have a need for a second transcatheter heart valve device or permanent pacemaker. [44]
