Mitral Valve Prolaps in Children - Retrospective Study 1999-2004

Introduction: According to the current literature, prevalence of mitral valve prolaps (MVP) in children is 10 %. Previous studies of patients with MVP have emphasized the frequent occurence of serious complications, new studies suggest more benign nature of MVP. The aim of this retrospective study was to determine the prevalence of MVP in the population of cardiac ambulance patients in the time period from10/1999 to 02/2004 and based on clinical follow up, estimate the clinical significance of MVP. Methods:The diagnosis was made according to the M-mode, by Feigenbaum. Mitral insufficiency was recorded using colour Doppler. Statistical significance between the groups was determined using Student test (t- test). Results: Among 1187 children, 688 had congenital hearth defect (57.9%), MVP was diagnosed in 51child (4.3%). In the group of patients with PMV there was 88.2% female and 11.8% male children. In the time of diagnosis mean age was 12.42 2.91 god. In 49.0% children prolapse was associated with mitral valve insufficiency. Those children were advised to take infective endocarditis prophylaxis prior to invasive procedures. The time of follow up was 3.17 0.85 year, or 161.78 years of follow up of all events in all patients. During follow up period there were no progression of insufficiency or other complications. Children with symptoms (72.5%) were more frequently treated with propranolol (p<0.01). Conclusion: The incidence of MVP is 4.3%. MVP is entity with good prognosis with need for infective endocarditis prophylaxis for group of patients with insufficiency. The children with profound symptoms should be treated by ß-blockers
