A 59-year-old male was admitted to the emergency room with signs of heart failure. The echocardiogram showed an extensive apical infarction with large mobile thrombi in the left ventricle. Doppler examination demonstrated apical rotating flow. Despite adequate anticoagulant therapy, the patient suffered a massive right-sided cerebral infarction leading to right ventricular cerebral compression. The thrombogenic risk of apical rotating flow and the need for anticoagulation are discussed.
