Cost consequence analysis of use of a balloon expandable vascular access system and standard vascular sheath for transcatheter aortic valve implantation

AbstractBackground: Vascular complications are an important complication of transcatheter aortic valve implantation and are associated with increased morbidity and mortality as well as cost. The Solopath device is an expandable vascular access system that has previously been shown to be associated with lower rates of vascular complications. This study sought to evaluate the impact of the use of this system on vascular complications and costs in a decision model analysis.Methods: A cost-consequence analysis was undertaken utilizing event rate data from the PARTNER trials and a published retrospective analysis of the Solopath device. The decision model estimated costs and benefits in a hypothetical cohort of patients with aortic stenosis undergoing TAVI using either a standard sheath or Solopath. The modeled analysis compared the occurrence of vascular complications and mortality at 30 days and 1 year using TreeAge Pro.Results: The decision model demonstrated that use of the Solopath sheath resulted in 36 f...
