Follow up of Moderate Aortic Regurge After Rheumatic Mitral Valve Replacement Clinical Trial
Official title:
Follow up of Moderate Aortic Regurge After Rhumatic Mitral Valve Replacement
Aim of the study is to follow of of moderate aortic regurge after mitral valve replacement to figure out if the aortic regurge has been improved or it is getting worse
A considerable proportion of patients who require mitral valve replacement present with a coexisting pathology of the aortic valve (AV). Rheumatic fever remains the leading cause for combined disease (1) Early series found that one-third of rheumatic hearts exhibited involvement of both mitral and aortic valve. The rate increased to 99% when the follow-up period was extended to 20 years The treatment of choice in cases in which one of the valves is moderately affected is questionable. Because combined aortic and mitral valve replacement is usually associated with higher risk and poorer long-term survival than replacement of either of the two valves alone (2) In patients with moderate aortic regurgitation who undergo mitral valve surgery). according to 2021 ESC/EACTS Guidelines, the decision to treat the aortic valve is controversial, as data show that progression of moderate aortic regurgitation is very slow in patients without aortic dilation (3) in contrast , In 2020 AHA guidelines recommended concomitant aortic valve replacement for moderate aortic regurgitation in patients undergoing surgery for ascending aorta, coronary artery bypass grafting (CABG),or mitral valve surgery (4-10) Because of this is a point of conflict we aim in this study to evaluate the saftey to leave moderate aortic regurge without intertvention as regarding operative time ,postoperative morbidity and mortality and progression of aortic valve regurge. ;
