A 69-year-old female patient presented to cardiac surgery department with unstable angina due to severe coronary artery disease. Coronary artery bypass grafting was indicated; however, the patient's symptoms of achalasia, previously treated by the pneumatic dilatation, exacerbated. Subsequently, the patient underwent simultaneous surgery. After sternotomy, on cardiopulmonary bypass, esophagus was exposed and Heller myotomy was performed. Following cardioplegia, coronary artery bypass grafting was completed. The postoperative course was uneventful, and the patient was discharged on postoperative Day 9. In conclusion, this novel surgical technique can be effectively used in such cases.
