In this paper, we present a detailed case study from our transplant evaluation clinic, focusing on a postpartum patient with end-stage heart and kidney failure being considered for heart transplantation. The evaluation revealed pituitary dysfunction, correlating with Sheehan syndrome, a condition arising from significant blood loss that leads to pituitary gland hypoperfusion and necrosis. This diagnosis is particularly noteworthy considering the pituitary gland's vital role in hormonal regulation, which impacts multiple organ systems. The gland's vulnerability to ischemia, especially due to its enlargement during pregnancy, is a critical factor. Our case highlights the necessity of thorough pre-transplant evaluations to identify reversible endocrine factors contributing to organ failure, emphasizing the complex interplay between endocrine health and organ transplant suitability. This study serves as an important reminder for clinicians to consider endocrine causes in transplant candidates, especially in postpartum patients.
