[Indications for percutaneous mitral commissurotomy].
Percutaneous mitral dilatation is now recognized as a valid alternative to open heart surgery. Indications have been clearly established for symptomatic patients with major stenosis (1.5 cm2, or 1 cm2/m2 body surface area). In other cases, the level of functional impairment, the anatomic state of the valve and the patient's past history must all be taken into consideration. In Western countries, there is a relatively large number of elderly patients with a moderately or severely damaged mitral valve. A critical evaluation of immediate and long-term outcome is required to determine the precise indications for dilatation and for surgery. Finally, these two methods should not be considered as contradictory but rather as complementary tools to control the natural history of the disease.
