Imaging of isolated ventricular non-compaction with dynamic cardiomyoplasty.

Isolated ventricular non-compaction of myocardium is an unclassified cardiomyopathy with an underlying mechanism of a morphogenetic abnormality involving an arrest of compaction of the loose myocardial meshwork during fetal ontogenesis. The diagnosis of this unusual condition can be readily mistaken for idiopathic dilated cardiomyopathy and it should be considered in evaluation of patients with dilated cardiomyopathy. We present an interesting image of isolated ventricular non-compaction of myocardium coexisting with dynamic cardiomyoplasty. A 45-year-old female patient was admitted to our hospital with worsening congestive heart failure. Seven years earlier, she had been diagnosed with ‘idiopathic dilated cardiomyopathy’ and
