Abstract

Implantation of blood pumps as temporary circulatory support device (TCSD) aims to provide life support for patients needing heart transplantation, but may not survive to so complex surgical procedure. TCSD must help to provide blood circulation for sufficient period (approximately 30 days) for patient clinical recovery and preparation for the transplantation. A correct choice of implant configuration for this type of blood pump brings important consequences and is directly related to the success of this treatment. Main objective of this project is to evaluate the assistance provided by TCSD in two different configurations: in series (apical-aortic) and in parallel (atrial-aortic). This experimental study will be performed using one hybrid cardiovascular simulator. Those two implant configurations (in series and in parallel) will be evaluated and compared. The pump will be connected to the simulator, providing assistance to a simulated weak heart. Those tests will be conducted in different pumping conditions (different degrees of heart failure). So, we expect to obtain better understanding of surgical techniques and pump control, as well as set knowledge of the differences between the two options of cannulation techniques.
