[Clinical aspects, diagnosis and surgical treatment of rupture of the mitral valve chordae].

The authors generalize experience in surgical treatment of 121 patients with mitral incompetence caused by rupture of the chordal threads. Prosthetics of the mitral valve was conducted in 103 patients, plastic correction--in 18 patients. Study of the etiomorphological aspects of the problem showed destruction of the fibrous framework of the chorda to be a compulsory component of rupture of the chordae of various origin. At the same time, there are some similar clinico-diagnostic manifestations of rupture of the chordae, which allows this form of mitral valvular disease to be set apart as an independent syndrome. Echocardiographic study is the most informative method in the diagnosis of the disease, it reveals rupture of the chordae in over 95% of cases. The immediate and late-term results of plastic operations and prosthetics were compared. Plastic operations are preferable in a favorable situation because survival after them is higher and thromboembolism does not develop even if anticoagulant therapy is not applied.
