Isolated noncompaction of the myocardium.
Noncompaction of the myocardium (NCM) is a rare congenital heart defect. It was first described 15 years ago, and few cases are published. The purpose of this study is to describe a NCM case. Clinical findings and imaging test results of a 37-year-old female patient with isolated NCM are presented. The patient complained of palpitations; her physical examination revealed extrasystoles, and her 12-lead electrocardiogram showed ventricular bigeminy. Three-dimensional Doppler echocardiography revealed numerous prominent trabeculations with deep intertrabecular recesses with blood flow which communicated with the ventricular cavity, which were more intense in the septal apical region. Cardiac magnetic resonance imaging corroborated the echocardiographic findings. The clinical presentation and the patients laboratory test results confirmed the diagnosis of isolated NCM. The knowledge of the echocardiographic findings of this disease enables an early diagnosis and a more adequate treatment.
