Isolated left ventricular noncompaction in adults is uncommon. The most frequent 
clinical manifestations are heart failure due to left ventricular systolic 
dysfunction and supraventricular and ventricular arrhythmias, which may be 
sustained and associated with sudden death. Thromboembolic complications are 
also possible. We report the case of an adult patient with isolated left 
ventricular noncompaction who came to our observation because of acute cerebral 
ischemia, an initial presentation of the disease only rarely described.
