A Case of Apical Hypertrophic Cardiomyopathy which Evolved from a Diffuse Left Ventricular Hypertrophy: 6 Year Follow Up

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.

We experienced a case of apical HCMP in 62-year-old female, which evolved during 6 years from mild, diffuse left ventricular hypertrophy to more progressed diffuse hypertrophy associated with marked hypertrophy of the apex of left ventricle showing ventriculopraphic picture of apical HCMP. The present case shows the morphologic change in HCMP with progression of hypertrophy during adult life.
