Non-compaction myocardium of the left ventricle (LVNC) is a genetically heterogeneous congenital cardiomyopathy characterised by excessive prominent trabeculations and deep intertrabecular recesses which communicate with the left ventricular cavity. Echocardiography plays a pivotal role as a first line diagnostic tool of this rare abnormality. We presented a case of 64-year-old male with LVNC and with papillary muscle involvement.
