[A familial form of ventricular non compaction in a mother and two of his sons in St. Louis, Senegal].

We report a familial form of ventricular non compaction in a mother and two of her sons. It was a young man of 25 years who presented with NYHA stage III dyspnea and a cough with bloody sputum. The clinical examination found left ventricular failure. The echocardiogram done showed left ventricular dilatation with large trabeculae separated by deep intertrabecular recesses in both ventricles suggestive of a non-biventricular compaction. It was possible to note from the family screening by echocardiography of the mother and half-brother a left ventricular non compaction while they were asymptomatic. Thus we concluded a familial form of ventricular non-compaction. This is the first familial case described in Senegal.
