Abstract
INTRODUCTION AND IMPORTANCE: Mitral insufficiency is a common valve disease with a prevalence of 2% and increases after the age of 65. This is the second valvulopathy operated after aortic stenosis. The surgical management of mitral insufficiency has been completely changed in recent years. The mitral valvular replacement with was the gold standard; is currently preceded by conservative surgery thanks to the emergence of reproducible and durable surgical techniques. The aim of our study is to highlight the place of Neogortex in the treatment of mitral valvular prolapse. METHODS: This is a retrospective study that includes 6 adult patients operated on for mitral insufficiency by prolapse of the large valve between October 2016 and June 2018 in the Cardiovascular Surgery Department A of the Ibn Sina Hospital in Rabat, Morocco. RESULTS: We collected 6 patients. The average age is 56 years. The clinical presentation was made of dyspnea in the 6 patients. On the echocardiographic level, all patients had mitral insufficiency due to prolapse of the large mitral valve in 2 patients and a restriction of the play of the valve by shortening of the ropes in 2 patients. The 6 patients were operated. The technique was the installation of a prosthetic ring with neogortex fixation between the free edge and the abutment and a tricuspid plasty type Devega. The operative sequences were simple. CONCLUSION: Mitral valve repair gives satisfactory results in terms of survival and symptomatic improvement with a low operative risk.
