Abstract

Isolated noncompaction of the ventricular myocardium (INVM) is a rare morphological abnormality caused by cessation of the compaction of the loose interwoven meshwork of myocardial fibers during intrauterine life. Three cases of INVM, including 2 siblings, were diagnosed from 2-dimensional echocardiographic findings of Wolff-Parkinson-White syndrome type B to which INVM can be attributed.
