Key result

Adding hyaluronidase to preservation solutions improves functional recovery and reduces edema in preserved rat hearts.

Why the study?

The effectiveness of preservation solutions for prolonged heart storage and the potential benefit of adding hyaluronidase were not fully established.

Does adding hyaluronidase to preservation solutions improve functional and metabolic recovery in preserved rat hearts?

Population

Rat hearts preserved by simple storage for 18 h at 0–1 °C and reperfused parabiotically with whole blood from a host rat

Comparison

Preservation solutions EuroCollins, HTK, or UW with 40 mg/l hyaluronidase or EFG solution versus hyaluronidase-free basic solutions

Design

Preclinical experimental study

Follow-up

18 h storage followed by reperfusion

Implication

Hyaluronidase addition improved recovery in rat heart preservation models; leaves open translation to clinical transplantation protocols.

Does adding hyaluronidase to preservation solutions improve functional and metabolic recovery in preserved rat hearts?

Population

Rat hearts preserved by simple storage for 18 hours at 0-1 °C and reperfused parabiotically with whole blood from a host rat.

Intervention

Preservation solutions (EuroCollins, HTK, or UW) with 40 mg/l hyaluronidase or Euro-Flush-Glutathione (EFG) solution

Comparator

Hyaluronidase-free basic solutions (EuroCollins, HTK, or UW)

Outcome

Functional recovery (LVP, dp/dt, isotonic stroke volume), metabolic recovery, and edema formationsurrogate

Adding hyaluronidase to preservation solutions like HTK improves functional and metabolic recovery of preserved hearts in a rat model.

Cite This Study

Fischer et al. (1996) studied Heart preservation. Hyaluronidase added to preservation solutions (EuroCollins, HTK, or UW) or EFG solution vs. Hyaluronidase-free basic solutions was evaluated on Functional recovery, metabolic recovery, and edema formation. Adding 40 mg/l hyaluronidase to preservation solutions, especially HTK and EFG, improved functional and metabolic recovery and reduced edema formation in preserved rat hearts.
