[Should mitral valve diseases, without or with few symptoms, be treated surgically?].
Our approach to the treatment of valvular heart disease, and mitral valve disease in particular, has been deeply modified by the experience acquired since the introduction of cardiac surgery and the technical advances in this field in the last decade and by new methods of investigative and interventional cardiology. In pure severe mitral regurgitation alone, the treatment of choice is reconstructive surgery. In the experience of our group, 191 patients out of 342 operated since 1970 for this type of valve lesion were referred for reconstructive surgery. Taking the results into consideration (72% 15 year survival), it is now justified to refer patients at a stage when the valvular disease is asymptomatic or pauci-symptomatic. A certain number of factors has to be assessed to evaluate the surgical indication: the experience of the surgical team, the etiology of the mitral regurgitation, the type of anatomical lesion, the stage of the cardiac disease and the patient's age. In mitral stenosis, in preference to surgical commissurotomy, percutaneous mitral valvuloplasty may be proposed in certain asymptomatic or pauci-symptomatic patients if the stenosis is severe, if the anatomical lesions are optimal and if there is a hemodynamic (pregnancy) or thromboembolic risk (arrhythmias, spontaneous contrast on transoesophageal echocardiography). In mixed mitral valve disease or very calcific stenoses, analysis of long-term results of valve replacement indicates that the late prognosis depends more on the stage of the cardiac disease at the time of surgery than on the type of prosthesis. It is advisable not to wait until an advanced stage before operating these patients when the valvular dysfunction is severe and there are hemodynamic consequences.(ABSTRACT TRUNCATED AT 250 WORDS)
