NON-COMPACT MYOCARDIUM AS A CAUSE OF THE DEVELOPMENT OF CHRONIC HEART FAILURE IN A YOUNG PATIENT

A 38-year-old patient was admitted to the hospital with symptoms of chronic heart failure. Dilated cardiomyopathy was diagnosed. An echocardiogram and magnetic resonance imaging revealed non-compact myocardium of the left ventricle in the apical sections up to 20 mm thick, an organized thrombus 11.9 × 14.4 mm, dilatation of the left chambers of the heart. Holter monitoring of the electrocardiogram diagnosed ventricular extrasystole grade V according to Ryan, prolongation of the corrected QT interval from 450 to 487 ms, short episodes of ventricular polymorphic tachycardia. Thus, non-compact left ventricular myocardium was the cause of chronic heart failure and a high risk of sudden cardiac death of a young patient.
