This report proposes a safer, economical method to examine the marginal donor heart for a better chance of use, which also delivers comparable image quality of catheterization (CathLab) without creating potential damage to the kidney. Currently the examination of the coronary system mainly relies on the CathLab, which is not commonly accessible, and also results in nephrotoxic effects. Therefore, bench coronary angiography is hereby proposed because it is commonly available and economical as well as able to indicate coronary lesions for surgeons as well as the CathLab study. These benefits altogether provide a better chance to select usable hearts from older donors to help relieve the organ shortage.
