Coronary artery bypass grafting in a patient with myasthenia gravis.

A 70-year-old male patient with myasthenia gravis required coronary artery bypass grafting due to triple-vessel disease. The anesthetic management was performed with general anesthesia using reduced doses of muscle relaxants. He was extubated four hours after surgery and the postoperative course was uneventful. Coronary artery bypass surgery in myasthenic patients can be challenging to anesthesiologists and cardiac surgeons. In this rare condition, a meticulous assessment of the patient's neurologic and cardiac status, and careful perioperative anesthetic management were needed in order to avoid life-threatening complications in both intraoperative and postoperative periods.
