Mechanical circulatory support creating treatment — total artificial hearts (TAH) providing complete heart replacement for end-stage heart failure patients ineligible for transplantation enabling bridge-to-transplant or destination therapy supporting patient survival and quality of life, establishing artificial hearts as critical cardiac intervention infrastructure, with the Total Artificial Heart Market experiencing expansion driven by heart failure prevalence growth, transplant shortage, and artificial heart technology advancement enabling improved outcomes.

Bridge-to-transplant strategy — total artificial heart enabling temporary support for end-stage heart failure patients awaiting heart transplant improving survival probability and quality of life during transplant wait. The bridge benefit — where mechanical support maintains function — supporting patient survival during transplant waiting.

Destination therapy option — total artificial heart enabling long-term support for transplant-ineligible patients providing alternative to inevitable death offering extended survival and improved quality of life. The destination benefit — where permanent support enables survival — transforming prognosis for ineligible patients.

Technology advancement — improved artificial heart designs with longer durability and reduced complications enabling broader patient application and improved outcomes. The technology benefit — where advanced designs improve durability — supporting longer-term mechanical support.

As total artificial heart technology advances and outcomes improve, how should the cardiac surgery and mechanical support communities develop appropriate patient selection criteria and shared decision-making frameworks ensuring that artificial heart therapy appropriately benefits carefully selected patients while managing realistic expectations regarding outcomes and supporting optimal long-term management?
