Left ventricular non-compaction; an unusual presentation with supraventricular tachycardia in the emergency department

Am J Emerg Med. 2019 Oct;37(10):1990.e1-1990.e2. doi: 10.1016/j.ajem.2019.158364. Epub 2019 Jul 23.

Abstract

Left ventricular non-compaction (LVNC) is a cardiomyopathy with altered ventricular wall anatomy. This condition is characterized by the presence of prominent left ventricular trabeculae, a thin compacted layer, and deep intertrabecular recesses that are continuous with the left ventricular cavity and separated from the epicardial coronary. Left ventricular non-compaction can present with acute heart failure, arrhythmias, or sudden cardiac death. We present a case of a common cardiac arrhythmia in the emergency department with a work up consistent with LVNC being the underlying etiology.
