Surgery for aortic dissection or to correct a major congenital heart defect.~6. Administration of iodinated contrast media within 24 hours prior to cardiac surgery or evidence of contrast-induced nephropathy prior to cardiac surgery.~7. Cardiogenic shock or hemodynamic instability within the 24 hours prior to surgery and requirement for inotropes or vasopressors or other mechanical devices, such as intra-aortic balloon counter-pulsation.~8. Requirement for any of the following within 7 days prior to cardiac surgery:~   * Defibrillator or permanent pacemaker;~  * Mechanical ventilation;~  * Intra-aortic balloon counter-pulsation;~  * Left ventricular assist device;~  * Other forms of mechanical circulatory support.~9. Known history of cancer within the past 2 years, except for carcinoma in situ of the cervix or adequately treated basal cell carcinoma of the skin.~10. Known or suspected sepsis at time of Screening or confirmed or treated endocarditis within 30 days prior to cardiac surgery.~11. Other current active infection requiring systemic antibiotic treatment.~12. Inadequate hepatic function, defined as total bilirubin or alanine aminotransferase or aspartate aminotransferase \>2X the upper limit of normal at time of Screening or Child Pugh Class C liver disease or higher.~13. Any congenital coagulation disorder.~14. Asplenia (anatomic or functional).~15. History of photosensitivity or active skin disease that, in the opinion of the Investigator, could be worsened by RBT-1.~16. Known hypersensitivity or previous anaphylaxis to SnPP or any tin-based product.~17. Serum ferritin \>500 ng/mL or those who have received IV iron within 28 days of Screening.~18. Pregnancy or lactation.~19. Treatment with an investigational drug or participation in an interventional study within 30 days prior to administration of study drug.~20. In the opinion of the Investigator, any disease processes or confounding variables that would inappropriately alter the outcome of the study.~21. Inability to comply with the requirements of the study protocol.
