RESTREPO, Gustavo; CASTANO, Rafael I  e  MARMOL, Alejandro. Non-compact left ventricle/hypertrabeculated left ventricle. Rev. Col. Cardiol. [online]. 2005, vol.12, n.1, pp.20-24. ISSN 0120-5633.

Non-compact left ventricle/hypertrabeculated left ventricle is a myocardiopathy produced by an arrest of the normal left ventricular compaction process during the early embryogenesis. It is associated to cardiac anomalies (congenital cardiopaties) as well as to extracardial conditions (neurological, facial, hematologic, cutaneous, skeletal and endocrinological anomalies). This entity is frequently unnoticed, being diagnosed only in centers with great experience in the diagnosis and treatment of myocardiopathies. Many cases of non-compact left ventricle have been initially misdiagnosed as hypertrophic myocardiopathy, endocardial fibroelastosis, dilated cardiomyopathy, restrictive cardiomyopathy and endocardial fibrosis. It is reported the case of a 74 years old man with a history of chronic arterial hypertension and diabetes mellitus, prechordial chest pain and mild dyspnea. An echocardiogram showed signs of non-compact left ventricle with prominent trabeculations and deep inter-trabecular recesses involving left ventricular apical segment and extending to the lateral and inferior walls. Literature on this topic is reviewed.
