This case involves a sixty-five-year-old male patient with a significant medical history of mitral valve dysfunction that required urgent repair. During the procedure, the surgeon nicked the patient’s internal mammary artery. As a result, the patient experienced significant intraoperative bleeding that caused massive strain on the heart tissue. The patient coded several times during the procedure but was able to be stabilized after ten units of blood were transfused. The patient was in the cardiac ICU for three weeks and was discharged from the hospital with a reduced ejection fraction due to the severe cardiac event experienced during surgery. Subsequently, the patient required close monitoring for impending heart failure and was in need of a heart transplant.
