Pediatric continuous-flow total artificial heart with rotor axial position tracking technology: First report of in vivo assessment.

ABSTRACT:

Background

The pediatric continuous-flow total artificial heart (P-CFTAH) is a novel double-ended centrifugal pump designed with the intent to provide circulatory support for pediatric heart failure. To enable continuous monitoring of pump hemodynamics, Hall effect sensors (HES) were embedded inside the P-CFTAH design to track both axial movement and position of the pump rotor postimplantation. Herein, we report an early in vivo evaluation of the P-CFTAH with HES, implanted in small-sized ovine models.

Methods

Five healthy lambs were used for the P-CFTAH implantation via a full median sternotomy and cardiopulmonary bypass support. Successful evaluation of the P-CFTAH was achieved in 4 out of 5 (n = 4, 20.9 ± 1.3 kg). The hemodynamics and operating conditions were cont
