Abstract

Background: The management of studied cases with moderate mitral regurgitation (MR) undergoing surgical aortic valve replacement (SAVR) remains debatable.
Objective: The aim of the current study to investigate the early results and fate of moderate MR after AVR.
Patients and methods: This study was both prospective and retrospective, conducted in the Cardiothoracic Surgery Department in the Faculty of Medicine at Cairo University, from March 2020 to October 2021. A total 200 studied cases undergoing AVR with moderate functional MR were screened. The fate of residual MR was evaluated by transthoracic echocardiography 6 months post-operative, and the prognosis of studied cases with residual MR.
Results: Up to 76% of the studied cases with moderate functional MR after isolated AVR enhanced mitral valve function, while 18% did not show a significant change, and 6% showed deterioration in mitral valve function over the short-term follow-up period. The decrease in MR is associated with the degree of LV acute reverse remodeling, which can be demonstrated by the decrease in LV end-diastolic volume. Perioperative morbidity did not find any significant variation among studied cases. The clinical outcomes showed significantly improved symptoms during the follow-up period for all patients. Conclusion: Patients with aortic valve disease and moderate functional MR should undergo AVR alone. The degree of MR will remain stable or may improve.
