[Congenital mitral valve malformations. Anatomical lesions and surgical treatment in paediatric age (author's transl)].
Congenital mitral valve malformations are diverse. When they present clinically in infancy medical treatment is often ineffective. Mitral valve replacement with prosthesis in children carries an high operative and postoperative risk. For these reasons the Authors have undertaken in 1972 a cooperative study which includes: 1) a surgical classification of the congenital mitral valve lesions; 2) a systematic attempt to repair the mitral valve. Over 43 observed cases, 18 have been operated upon. Eleven cases (61%) presented associated cardiac lesions. Hospital mortality was 16% (3 cases). There have been either mortality nor morbidity in the follow-up period. Eight cases have been recatheterized two years after the operation. The pulmonary artery pressure has significantly decreased and the mitral insufficiency disappeared almost completely. The classification, suggested by the Authors, is explained in details.
