Effect of the diastolic and systolic duration on valve cavitation in a pediatric pulsatile ventricular assist device.

Abstract

Minimization of cavitation is of high importance in the design of pulsatile ventricular assist devices because cavitation can cause blood and valve surface damage. Cavitation is associated with valve closure and has been previously correlated to high dP/dt, high valve closing velocity, and decreased pump filling. In this study, the effects of diastolic and… (More)
