Possible New Method for Evaluation of Mitral Valve Prolapsus (MVP) in Children and Adolescents
並列摘要
The true prevalence of mitral valve prolapsus (MVP) is not known due to implementation of diferential exploration techniques and diagnostic criteria. It varies from the very low 0.4% to the very high 35%, in respect to gender and age. According to the international data, MVP prevalence is estimated to be about 1-2% among children and 5-15% among adolescents. The objective of this study was to determine the potential new exact method for MVP diagnostics in children and adolescents, comparable to the ”golden standard”. This study summarizes results generated through general check-ups of 2018 school children, ages 7-19, 1049 females and 969 males. Diagnosis by method of auscultation with electronic stethoscope and phonocardiographic analysis of digitalized audio file, compared to echocardiographically confirmed MVP indicates that the accuracy of the data gathered by usage of electronic stethoscope, in comparison to the golden standard (echocardiography) on the level of trust, is 0.74 and 0.72 and, accordingly, 0.80 and 0.77. Statistical analysis demonstrated there was no difference in MVP morbidity as related to gender, enabling interpolation of the generated data for children of both genders, which indicated that the prevalence of MVP among children ages 7-19 was 3%, whereas in children ages 10-18 it increased linearly with age and peak of 18% at the age of 16. Our results showed that this new method could provide additional reliability and comfort during evaluation of MVP.
