May support nonpulsatile rotary pumps for durable MCS; leaves open need for prospective validation before practice change.
Nonpulsatile rotary blood pumps are proposed as a simpler, more durable alternative to pulsatile pumps for permanent mechanical circulatory support.
Nosé et al. (1996) reported a review. Nonpulsatile permanent rotary blood pump vs. Pulsatile blood pump was evaluated. A nonpulsatile rotary blood pump utilizing a 20% higher blood flow than required for a pulsatile pump avoids circulatory abnormalities and offers a durable design for permanent implantation.
