Mitral valve replacement in children.

摘要: BACKGROUND AND AIMS OF THE STUDY Although repair of the mitral valve in children with or without concomitant congenital heart defects has improved significantly, it is not always achievable. The study aim was to review a 20-year experience replacement (MVR) children. METHODS Since 1980, 90 patients (37 males, 53 females; mean age 8.1 years; range: 3 weeks 18 years) have undergone total 102 MVR operations (12 redo-MVR, nine multiple valves, and three common atrioventricular replacement). Tissue valves were used 13 (14%). etiology for disease 72 (80%), 34 had septal defect (AVSD). Other etiologies included rheumatic (n = 8), myxomatous 4), endocarditis 3), Kawasaki disease, left atrial myxoma idiopathic hypertropic subaortic stenosis (each n 1). In total, 36 (40%) previous repair, (38%) associated lesions. RESULTS Hospital mortality significantly higher aged < 2 years (52%, 15 29) compared older (3%, 61) (p 0.001). Fourteen hospital deaths failed complex defects, mainly AVSD under years, followed by MVR. Mean follow up 9.3 (range: 7 months 21.5 years). There four late deaths; major events thromboemboli 6), bleeding 9), 1) cardiomyopathy orthotopic transplantation 7). CONCLUSION good surgical option nonrepairable over years. following carries high incidence morbidity mortality.
