LONDONO-CADAVID, Alexander et al. Imaging clinical characterization of patients with left ventricular noncompaction. Rev. Colomb. Cardiol. [online]. 2016, vol.23, n.3, pp.191-199. ISSN 0120-5633.

Motivation: Left ventricular noncompation is increasingly diagnosed in the world, with a significant impact on morbidity and mortality. There is no local register describing the profile of affected patients. The goal is to describe demographic, clinical and imaging characteristics of patients diagnosed with left ventricular noncompaction in a regional register. Methods: Cross-sectional descriptive study including patients with left ventricular noncompaction suspicion due to an echocardiogram, confirmed with a magnetic resonance with contrast. Patients’ medical records and images obtained between 2006 and 2013 were assessed. Demographic, clinical and imaging characteristics were analyzed. Anatomical characterization and ejection fraction were based on the magnetic resonance. Results: 33 patients diagnosed with left ventricular noncompaction via magnetic resonance were included. The average age was 21.9 ± 19.8, pediatric population was the most representative (30.3% between 1 and 10 years old and 30.3% between 11 and 20 years old). There was a 63% diagnostic coincidence between echocardiogram and magnetic resonance; most common symptoms were dyspnea, chest pain and palpitations (78,8, 36.4, 33.3% respectively). Cardiac failure was the syndrome prevalent to diagnosis (51.5%). Most patients suffered from left ventricular noncompaction <40% (57.6%), normal left ventricular noncompaction 21.2%. Apical lateral walls were the most compromised (48.3%). The symptoms and presence of an embolism were more related to the severity of the systolic dysfunction. Conclusions: Left ventricular noncompaction is an increasingly common diagnosis in the local area and its presentation and progress are similar to series from other countries. Suspicion in the echocardiogram is correlated to findings in the magnetic resonance. Diagnosis in infants and adolescents is usually reached at an advanced stage.
