Development of heart failure and stroke in the setting of myocardial noncompaction

We present a 30-year-old male patient who developed new-onset heart failure and stroke in the setting of myocardial noncompaction. He presented with shortness of breath that progressively worsened in the past 15 days. Chest X-ray showed diffuse bilateral infiltration with bilateral hilar fullness. Electrocardiography showed sinus rhythm, signs of left ventricular hypertrophy, and diffuse T-wave negativity. Transthoracic echocardiography demonstrated moderate systolic dysfunction of the left ventricle and trabeculations and intertrabecular recesses in the anterolateral and apical regions of the inferior wall. Dense spontaneous echo contrast was seen in the left ventricular cavity. He also had a bicuspid aortic valve. The patient developed stroke at the eighth hour of hospitalization. Heparin infusion and heart failure treatment were started. Transesophageal echocardiography showed no thrombus. Clinical and radiological findings improved significantly during the follow-up. Oral anticoagulant therapy was initiated and the patient was discharged with control recommendations. Myocardial noncompaction was also demonstrated by cardiac magnetic resonance imaging.
