The economics of TAVI: A systematic review

Objective: The scope of this systematic review is to update the existing body of evidence regarding the costeffectiveness of transcatheter aortic valve implantation, stratified across all risk categories, and to assess their methodological quality.Methods: A systematic review was performed including published cost-effectiveness analyses of heart valve implantations. The quality was assessed with the Quality of Health Economics Tool. Results: We identified 33 economic evaluations of transcatheter aortic heart valve implantations.Results were not consistent, ranging from dominant to dominating. Moreover, the models were sensitive to an array of variables. The methodological quality of the studies was good.Conclusion: This systematic review led to inconclusive and inconsistent results pertinent to the economic profile of TAVI technology. It also highlighted areas which merit further research regarding the pillars of costeffectiveness analysis such as modeling, the extrapolation of available data and the uncertainty of the evidence. A thorough assessment of the patient should proceed any decision-making.
