Background: We report our experience of cardiac surgery with concomitant pulmonary resection, based on analysis of the results. Methods: Eleven patients (1 woman, 10 men) underwent cardiac surgery simultaneously with pulmonary resection; ten of them through median sternotomy. The cancer pathology consisted of non-small cell carcinoma (n = 10), and benign teratoma (n = 1). All lung lesions were removed using a wedge resection. Cardiac procedures consisted of off-pump coronary artery bypass grafting (n = 4), aortic valve replacement (n = 3), mitral valve plasty (n = 2), total arch replacement (n = 1), and descending aorta replacement (n = 1). Lung wedge resections were performed after induction with protamine sulfate. Results: The mean follow-up period was 19 卤 11 months (2-34). There was no operative mortality and no major cardiac complications. Three patients underwent a subsequent lobectomy through lateral thoracotomy. There were two postoperative deaths: one was from an unknown cause, 8 months postoperatively and another was from a lung cancer recurrence, 9 months after surgery. There were two local recurrences, 9 months and 14 months, postoperatively. The mean cancer-free period was 17 卤 10 (2-32) months. Conclusion: Rates of operative mortality and morbidity following cardiac surgery with concomitant pulmonary resection were favorable, and early to midterm results were acceptable.

Some institutions conduct a staged surgical procedure in which the cardiac surgery is mostly performed first followed by the lung surgery. Potential problems with this approach include delay in the lung resection due to the postoperative recovery phase and the additional cost of two operations. However, the concomitant procedure also has its shortcomings, such as the risk of dissemination due to manipulation of the pulmonary lobe, mechanical stress on the cardiac chambers, inability to perform radical lymph node dissection, and the risk of increasing the amount of blood loss due to the effect of heparinization.We studied a series of eleven patients who underwent concomitant pulmonary wedge resection and cardiac surgery. The aim of the study was to analyze the outcome of
