Abstract		We studied the prevalence of mitral valve prolapse (PMV in the group of 656 children and adolescents (329 men, 327 women) who performed a representative sample, got with the Monte Carlo method of statistical trials, of all the newborns born in the city of Maribor, Republic Slovenija in the last 18 years. We considered positive results in those children and adolescents who with supposed anamnestical (precordial pain, palpitations, dizziness, sincope, headache, perspiration), probable auscultational (mesosystolic click and late systolic murmur), suspectable phonocardiographic and ECG findings also had positive ECHO M-mode finding. The criterions for the PMV on the M-mode ECHO were taken according to the literature; mitral cuspis, the front or the rear one must descend at least 3 mm below the line connecting points C-D. Children and adolescents were divided into 6 groups according to the age (newborns, erly preschool children, preschool children, early school children, children in puberty, adolescents). Assuming PMV as a cause of cardiac arrhythmias beside standard ECG we also performed Holter ECG in the subgroup of 61 children and adolescents (29 with PMV, 32 without PMV). The results were tested with standard statistical tools and methods (xi2 test, Student t- test, 2x2 Fisher xi2 test). The PMV was found in 71 patients (10,8%); (32 men, 39 women). According to the age and sex we found lower prevalence of the PMV in male children (9,7%) related to the female children (11,9%). The highest prevalnce of the PMV was found in the group of early school children, more in the female group (14,2: 13,7%). The prevalence of the PMV rises with age in both sexes. The most frequent in both sexes is telesystolic prolapse (men 59,3%, women 51,3%) of the both cuspis's (men 78,1%, women 66,7%). The most repeated measured descending of the cusps was 3-4,5 mm (men 56,2%, women 48,7%).(Abstract truncated at 2000 characters.)
