title: [Current anatomical and etiological aspects of chronic or subacute, surgical, pure mitral valve insufficiency in adults. Apropos of 75 medicosurgical cases].
abstract: Seventy five medico-surgical cases (52 men, with a mean age at surgery of 59, and 23 women, with a mean age at surgery of 59) collected between 1983 and 1989, in an ethnically homogeneous and geographically stable population (West Brittany) confirmed that the current anatomical and etiological aspects of chronic (or subacute) pure mitral incompetence (MI) have changed radically. While rates for bacterial and ischemic etiologies remain stable, the share of rheumatic MI (14 cases) has fallen considerably, to the advantage of degenerative MI (51 cases) with a heavy male predominance (39 men) with in 33 cases rupture of the main chordae, and tending to affect the lesser mitral cusp more often. A precise diagnosis in terms of lesions and etiology is possible in almost all cases on the basis of clinical history and echocardiographic findings. In a perfectly homogeneous population, chronic surgical pure MI is currently essentially a male disease, of dystrophic origin, in patients in the 6th and 7th decades of life.
