Comparative study of outcomes of different approaches in redo mitral valve surgery

Abstract

Background Redo mitral valve replacement surgery is a challenging procedure as the access of the mitral valve mandates good exposure yet mitral visualization may not be sufficient as previous cardiac operations may complicate mitral valve exposure, as adhesions and loss of mobility in the surrounding tissues may be present. In such cases, the conventional left atrial incision may not offer satisfactory visualization in the surgical site of the valve. Therefore, several alternative approaches have been proposed, such as superior trans-septal approach, for satisfactory visualization of the mitral valve intra-operatively. Patients and methods Between January 2017 and November 2021, 100 patients were enrolled and with 50 patients randomly assigned in each group. Group one on patients undergoing redo surgery via a superior trans-septal approach and group two undergoing redo surgery via left atrial approach. Results Transeptal approach provides same results like left atrial approach in redo mitral valve surgery. Conclusion We conclude that the transseptal approach when compared to left atrial in redo patients provides comparable results in the intraoperative as well as postoperative outcomes
