Cardioplegia deli very systems require significant modifications to accommodate the small pediatric patient. This new system employs the combination of a low prime heat exchanger, recirculation line systems and an open reservoir for use in both blood and crystalloid cardioplegia circuits. This modification is designed to minimize priming volume to approximately 50 ml, making it suitable for the very small patient. Simple tubing and reservoir variations can be made for the larger patient while still demonstrating excellent cooling, mixing and blood flow capability while safely delivering cardioplegia to the pediatric patient.
Key words: heat exchanger / low prime / cardioplegia system / hemodilution
