Off-pump coronary artery bypass grafting in a patient with chronic myelomonocytic leukemia.

We report the case of a 71-year-old man with chronic myelomonocytic leukemia who developed cardiogenic shock twice due to a stenosis of the left main trunk of the coronary artery. We performed coronary artery bypass grafting to the left anterior descending artery with the left internal thoracic artery without using a cardiopulmonary bypass. The patient had no infection, leukemic transformation, or cardiac event after the surgery. Off-pump coronary artery bypass grafting is safe and useful for high risk patients, such as those with leukemia.
