Myopathy, Left Ventricular Noncompaction, and Tetralogy of Fallot

AbstractLeft ventricular hypertrabeculation, also termed noncompaction (LVHT) is a cardiac abnormality characterized by excessive trabeculations of the left ventricular cavity. LVHT may be associated with extracardiac abnormalities, most frequently neuromuscular disorders (NMDs). LVHT associated with tetralogy of Fallot (ToF), so far, has been reported in 2 cases, but no indication for the presence of NMDs are given.We present a 47‐year old female who underwent 2 cardiac surgeries because of ToF, and was admitted because of heart failure. She was diagnosed with echocardiographic LVHT. A myopathy was diagnosed by biopsy. Copyright © 2009 Wiley Periodicals, Inc.
