Pediatric Ventricular Assist Device

Design of a continuous flow centrifugal pediatric ventricular assist device.

Thousands of pediatric patients suffering from cardiomyopathy or single ventricular physiologies secondary to debilitating heart defects may benefit from long-term mechanical circulatory support due to the limited number of donor hearts available. This article presents the initial design of a fully implantable centrifugal pediatric ventricular assist device (PVAD) for 2 to 12 year olds. Convent...

Fluid dynamics of a pediatric ventricular assist device.

The number of pediatric patients requiring some form of mechanical circulatory assistance is growing throughout the world because of new surgical procedures and the success of pediatric cardiac transplantation. However, the salvage rate for those patients requiring circulatory support may be as low as 25%. Despite the fact that Penn State's 70 cc pneumatic ventricular assist device has been use...

Prospective trial of a pediatric ventricular assist device

Thermal Analysis of the PediaFlow pediatric ventricular assist device.

Accurate modeling of heat dissipation in pediatric intracorporeal devices is crucial in avoiding tissue and blood thermotrauma. Thermal models of new Maglev ventricular assist device (VAD) concepts for the PediaFlow VAD are developed by incorporating empirical heat transfer equations with thermal finite element analysis (FEA). The models assume three main sources of waste heat generation: coppe...

Pediatric ventricular assist devices.

The field of pediatric mechanical circulatory support with ventricular assist devices has lagged significantly behind that of adult patients. However, there is increasing attention on the emerging field of pediatric ventricular assist device support. In this review, part of the Pediatric Cardiac Intensive Care Society/Extracorporeal Life Support Organization Joint Consensus Statement on Mechani...
