Left ventricular noncompaction: diagnosis by three-dimensional echocardiography.
(5/37)
Left ventricular noncompaction (LVNC) is a rare congenital disease caused by an arrest in normal myocardial embryogenesis, leading to persistence of numerous prominent trabeculations that communicate with the left ventricle. It was first described as a congenital condition affecting children, but several cases have been reported of late presentation. The main clinical manifestations are congestive heart failure, arrhythmias (supraventricular or ventricular) and systemic embolism. We present the case of a 51-year-old patient brought to our emergency department after an episode of symptomatic ventricular flutter requiring electrical cardioversion. Two-dimensional echocardiography with color Doppler suggested the diagnosis and the three-dimensional echocardiogram revealed the deep trabeculations typical of LVNC. (+info)

Heart transplantation in an adult patient with isolated noncompaction of the left ventricular myocardium.
(8/37)
Isolated noncompaction of the ventricular myocardium is defined as a rare cardiomyopathy caused by intrauterine arrest of compaction of the myocardial fibers and meshwork, an important process in myocardial development, in absence of any coexisting congenital heart lesions. A lot of controversies exist about diagnostic criteria, nomenclature, origin, pathogenesis, and prognosis of this disease. Here, we describe an adult patient with isolated left ventricular noncompaction who presented with worsening congestive heart failure and was successfully treated with heart transplantation. (+info)
