Abstract

Mitral valve prolapse plays an important role in cardiovascular pathology in children. The study reveals the condition of the central hemodynamic and echomorphometric parameters in children with mitral valve prolapse (MVP) taking into account mitral regurgitation.

Materials and methods. We examined 106 children with MVP. Among them there were 90 children with MVP of 1st degree and 16 children with the 2nd degree aged from 13 to 17 years. The presence and absence of mitral regurgitation were included also. Thus, 56 (52.8%) children with MVP of the 1st degree formed subgroup without mitral regurgitation, and 34 (32.1%) – with regurgitation. MVP of the 2nd degree formed subgroup which included children both without – 6 (5.6%) and with regurgitation – 10 (9.4%). The control group consisted of 23 almost healthy children of the same age. All patients were clinically examined and consulted by specialists. Common echocardiographic parameters were used for the study.

Results. An increase (p<0.05) of E/A parameter in children with MVP was noted, mainly with 1st degree. It showed the initial manifestations of diastolic dysfunction of the heart. This indicator increases with regurgitation appearance and depends from the MVP degree (r=0.45). Hemodynamics was generally within normal criteria.

Conclusions. In children with mitral valve prolapse, regardless to degree, normovolemic and eukinetic type of central hemodynamic was observed. Children with MVP with regurgitation appearance have increased risk of left ventricular diastolic dysfunction. With the progression of mitral valve prolapse, manifestations of diastolic myocardial dysfunction increases. This category of children must have preventive methods to restore echomorphometric parameters for reducing complications occurrence.
