Noncompaction of the left ventricular myocardium (LVNC) is a rare cardiomyopathywith a spectrum of clinical presentations. The pathogenesis of this type of cardiomyopathyinvolves an arrest in the process of compaction during embryonic life. Identificationof high risk individuals with this syndrome is challenging; it can cause presentationsranging from an asymptomatic state to malignant ventricular arrhythmias and suddendeath. We present a 19-year-old man who presented with syncope and was later diagnosedwith left ventricular noncompaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
