What is a requirement for pair displacement pumps used in heart support systems?

For pair displacement pumps used in heart support systems, eligibility for transplant is a critical requirement. These heart support systems are often utilized as a bridge to transplantation for patients who are experiencing severe heart failure and whose condition is too unstable to proceed directly to transplantation. The underlying purpose of these devices is to help improve a patient's hemodynamics and stabilize their condition while they await an appropriate donor heart.

Candidates for these systems are typically evaluated on their potential to receive a transplant successfully. This typically includes assessing their overall health, the severity of their heart condition, and their predicted outcomes following transplant surgery. Therefore, being eligible for transplant signifies that the patient has been assessed as suitable for further treatment options, which aligns with the use of pair displacement pumps.

In contrast, being under a specific age, having a significant cardiac history, or engaging in regular exercise are not necessarily requirements or indicators of suitability for heart support systems. The focus is primarily on the overall health status and transplant eligibility to ensure the best possible outcomes for the patient.
