Cardiovascular disease in patients with congenital hypopituitarism is not rare; however, there is a lack of reports referring to cardiac interventions in such patients. We present a 76-year-old man with complete pituitary hormone deficiency, who presented with recurrent events of unstable angina. He had a significant stenosis of the left anterior descending artery and he underwent off-pump coronary artery bypass. Our aim is to present the successful management of this patient with congenital hypopituitarism who underwent cardiac surgery and to review the relevant literature.
