It is known that the morphologic expression or progression of hypertrophy in hyertrophic cardiomyopathy(HCMP) occurs mostly during childhood, when the body growth is considerable, but nearly not occurs in adult life. Apical hypertrophic cardiomyopathy is an uncommon variant of HCMP which is characteristic apical hypertrophy of the left ventricle showing characteristic ace of spade diastolic configuratioin of the left ventriculogram. It has not yet been clarified when the progression or development of hypertrophy occurs in apical HCMP. The possibliity of the morphologic changes in apical HCMP has been poposed in previous study, but not proved yet.
