Diagnostics of combined hereditary cardiovascular pathology in a teenager

Dilated cardiomyopathy is one of the leading causes of heart failure in children with a variety of clinical characteristics. A 12-year-old patient with dilated cardiomyopathy and heterozygous familial hypercholesterolemia, who underwent surgical treatment for implantation of the Abbott HeartMate III Left Ventricular Assist Device as a bridge to donor heart transplantation, is presented. Establishing an accurate diagnosis in the presented observation became possible thanks to the use of a modern molecular genetic method — whole genome DNA testing by next generation sequencing (NGS). The description of this case will help expand the range of possible clinical manifestations of dilated cardiomyopathy and reminds us of the importance of dynamic monitoring of children with cardiac arrhythmias.
