The operation for constrictive pericarditis after coronary artery bypass grafting (CABG) needs complete pericardiectomy without injury to the bypass graft. A 60-year-old man had pleural effusion a month after CABG. Right atrial pressure (RAP), right ventricular pressure (RVP), and pulmonary capillary wedge pressure (PCWP) were elevated and RVP showed a dip and plateau sign on cardiac catheterization. We diagnosed heart failure due to constrictive pericarditis following CABG. Pericardiectomy was performed using a cardiopulmonary bypass through a median sternotomy. The Harmonic Scalpel was useful for dissecting the pericardium. After the operation, it took a month for the patient to improve. RAP, RVP and PCWP were decreasing, and the dip and plateau sign of RVP was improved. The pleural effusion disappeared and the patient was discharged on the 73rd postoperative day.
