Redo Surgery in Mitral Valve Diseases

Abstract

This is a retrospective study of a total 70 patients underwent redo mitral valve surgery from 2010 to 2015 in Ibn Al-Bitar Cardiac Center at Baghdad. The objectives of this research are to discuss the outcome of redo surgery in mitral valve, assesses the causes of death for surgery in patients underwent a mitral valve redo surgery, and evaluation of the late outcomes after mitral valve surgery especially after open and closed valvotomy. The gender of our patients is 64% females and 36% males; the middle old age of the suffers at the redo surgery time was 39.6 years (ranged from 13-65 years). Previous mitral surgery was closed mitral commissurotomy (CMC) in 30 patients (42%), mitral valve replacement (MVR) in 20 patients (29%), opened commissurotomy of miral valve in 12 suffers (19%) while repair of mitral valve in 8 suffers (10%). Re-operative surgery included mitral valve replacement with mechanical valves St. Jude type in all suffers . The mean time to redo surgery was 15 years run between 6 months – 35 years. Surgical indication were valve restenosis after open type of commisurotomy & closed type of commisurotomy in 40 patients were restenosis of valve surface area of prosthesis in 10 patients, mitral regurgitation in 8 patients, infected endocarditis in 6 suffers and paravalvular leak in 6 suffers. An operative mortality was 14% (10 patients). We now have proven in this be trained that mitral valve reoperations can be done with a suitable death rate at surgery that compares nicely with results in other studies.
