Systems, methods, compositions and solutions for perfusing an organ

1. A perfusion system configured for maintaining an ex-vivo heart in a functioning state under physiological or near physiological conditions comprising:

a first chamber containing a first solution comprising one or more cardio stimulants selected from the group consisting of catecholamines, peptides, polypeptides, β1/β2-adrenoreceptor blocking agents, buplinarol, pindolol, alprenolol, cardiac glycosides, digitalis, palustrin, and ferulic acid; and a plurality of amino acids selected from the group consisting of alanine, arginine, aspartic acid, glutamic acid, histidine, isoleucine, leucine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine, and lysine that do not include asparagine, glutamine, and cysteine;

a second chamber containing a second solution comprising one or more carbohydrates selected from the group consisting of monosaccharides, disaccharides, oligosaccharides, and polysaccharides; and

a third chamber containing a priming solution comprising mannitol, sodium chloride, potassium chloride, magnesium sulfate heptahydrate, and sodium glycerophosphate.

2. The perfusion system of claim 1 , wherein at least one of the first solution, second solution, or priming solution is sterilized prior to using the solutions to perfuse the heart.

3. The perfusion system of claim 1 , wherein the one or more cardio stimulants includes epinephrine.

4. The perfusion system of claim 1 , wherein the one or more carbohydrates in the second solution includes dextrose.

5. The perfusion system of claim 1 , wherein the first solution includes adenosine.

6. The perfusion system of claim 1 , wherein the first solution includes insulin.

7. The perfusion system of claim 1 , wherein the first solution includes an immuno-suppressant.

8. The perfusion system of claim 1 , wherein the first solution includes a multi-vitamin composition.

9. The perfusion system of claim 1 , further comprising one or more electrolytes in the first solution.

10. The perfusion system of claim 9 , wherein the one or more electrolytes includes calcium.

11. The perfusion system of claim 1 , wherein the solutions are combined with a blood product prior to perfusing the heart.

12. The perfusion system of claim 1 , further comprising a therapeutic agent.

13. A kit for use in a perfusion system that is configured for maintaining an ex-vivo heart in a functioning state under physiological or near physiological conditions, the kit comprising:

a first solution comprising one or more carbohydrates selected from the group consisting of monosaccharides, disaccharides, oligosaccharides, and polysaccharides,

a second solution comprising one or more cardio stimulants selected from the group consisting of catecholamines, peptides, polypeptides, δ1/β2-adrenoreceptor blocking agents, buplinarol, pindolol, alprenolol, cardiac glycosides, digitalis, palustrin, and ferulic acid; and a plurality of amino acids selected from the group consisting of alanine, arginine, aspartic acid, glutamic acid, histidine, isoleucine, leucine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine, and lysine that do not include asparagine, glutamine, and cysteine, and

a priming solution comprising mannitol, sodium chloride, potassium chloride, magnesium sulfate heptahydrate, and sodium glycerophosphate,

and a package.
