Noncompact left ventricular myocardium (clinical case)

The paper presents the clinical case of a 28-year-old patient, diagnosed noncompact myocardium of the left ventricle. The disease debuted from heart rate disturbance; Lown’s grade 4B ventricular premature beats were revealed according to the results of durable electrocardiogram monitoring. In echocardiography, significant decrease in the left ventricular ejection fraction was stated. After magnetic resonance imaging of the heart, the presence of two layers of myocardium, compact and noncompact with the latter exceeding the compact layer more than twofold was diagnosed. The patient underwent slow titration of the dose of angiotensin-converting enzyme inhibitors up to the maximum under the arterial pressure control. The following recommendations were given: anticoagulants for primary prevention of thromboembolic complications, planned implantation of a two-chamber artificial cardioaverter-defibrillator for primary prevention of sudden heart death.
