Noncompaction cardiomyopathy historical perspective

Overview
Non compaction cardiomyopathy was first identified as an isolated condition in 1984 by Engberding and Benber. They reported on a 33 year old female presenting with exertional dyspnea and palpitations. Investigations concluded persistence of myocardial sinusoids (now termed non compaction). Prior to this report, the condition was only reported in association with other cardiac anomalies, namely pulmonary or aortic atresia. Myocardial sinusoids is considered not an accurate term as endothelium lines the intertrabecular recesses.
