Isolated ventricular non-compaction is a rare congenital cardiomyopathy, 
manifested morphologically as prominent myocardial trabeculations and deep 
inter-trabecular recesses that communicate with the ventricular cavity. Heart 
failure is the most common presenting condition. Other manifestations include 
arrhythmia and cardioembolic events. This report is illustrative of isolated 
ventricular non-compaction in a 78-year-old woman. The diagnosis was made when 
she presented with ventricular tachycardia many years after a stroke. She 
subsequently underwent implantation of a cardioverter-defibrillator. This report 
documents an uncommon presentation of this disease entity in the oldest patient 
at presentation as yet reported in the literature.
