Redo cardiac surgery in patients with cardiac operations is a burden for both the patients and surgeons. Difficulties in exploration and further myocardial damage in recurrent operations are the main issues. Patients with recent operations pose another high-risk group. Herein, we presented two patients, a 67-year-old male and a 45-year-old male, who required mitral valve replacement surgery four weeks after surgical coronary revascularization due to pulmonary edema. The first patient had poor left ventricular functions and was operated on with beating heart surgery with cardiopulmonary bypass via mini anterior thoracotomy. The other patient was operated on with a conventional method.
