Although “spongy myocardium” was first observed by Grant in 1926, left ventricular noncompaction (LVNC) cardiomyopathy was originally described by Engberding and Bender in 1984.¹ Left ventricular noncompaction cardiomyopathy is characterized by abnormal ventricular myocardial protrusions with a thin layer of properly compacted myocardium.^2,3 It is a rare entity, with a prevalence less than 0.02%.⁴ We report a case of LVNC cardiomyopathy with dyssynchrony, which was successfully managed with cardiac resynchronization therapy (CRT).
