Isolated Left Ventricular Noncompaction in a Case of Sotos Syndrome : A Casual or Causal Link?

الملخص EN

A 16-year-old boy affected by Sotos syndrome was referred to our clinic for cardiac evaluation in order to play noncompetitive sport.

Physical examination was negative for major cardiac abnormalities and rest electrocardiogram detected only minor repolarization anomalies.

Transthoracic echocardiography showed left ventricular wall thickening and apical trabeculations with deep intertrabecular recesses, fulfilling criteria for isolated left ventricular noncompaction (ILVNC).

Some sporadic forms of ILVNC are reported to be caused by a mutation on CSX gene, mapping on chromosome 5q35.

To our knowledge, this is the first report of a patient affected simultaneously by Sotos syndrome and ILVNC.
