MITRAL VALVE REPLACEMENT WITH RESYNCHRONIZING DEVICE IMPLANTATION IN A 6-YEAR-OLD CHILD WITH DILATED CARDIOMYOPATHY
Dilated cardiomyopathy is the most common form of cardiomyopathy which found in children, characterized by an expansion of the heart chambers, a sharp decrease in the contractility of the myocardium with the rapid development of heart failure. Clinical signs of the disease often appear suddenly as the symptoms of rhythm disorders and heart failure. In this time pharmacological therapy is used for stabilize the patient's condition, but it doesn't prevent the progression of the pathology. Heart chambers enlarge quickly. It leads to relative valves insufficiency, which further aggravates the course of heart failure. In such case, it is often necessary to resort to surgical methods of treatment, such as a correction of valvular insufficiency (repair or replacement), or donor heart transplantation. The prognosis for this disease is serious, but it often remains unpredictable in relation to the duration and quality of life of patients. This report discusses a case of successful mitral valve replacement with simultaneous resynchronizing device implantation in a child with dilated cardiomyopathy.
