The course of the dilated cardiomyopathy in three siblings - a rare case of familial non-compact left ventricle.

The dilated cardiomyopathy still remains a big problem in infant's cardiology. Almost a third of patients with this diagnosis die in infancy, 30% will suffer from the chronic heart failure that forces constant treatment or/and heart transplantations, and in remaining 30% we notice improvement during infancy. We presented the clinical course and progress of dilated cardiomyopathy based on the case of three siblings. Signs of the heart failure were nonspecific. Concluding: diagnostic vigilance must be shown in the cases of positive familial history.
