Inferior Hypertrophic Cardiomyopathy: An Unusual and Insidious Site.

Hypertrophic cardiomyopathy is a heart muscle disease, characterized by increased left ventricular wall thickness that is not explained only by abnormal loading conditions. Hypertrophy preferentially involves the interventricular septum in the basal segments of the left ventricle, but often extends to the lateral wall, posterior septum, and apex of the left ventricle. A substantially isolated inferior wall hypertrophy is quite rare and diagnostically insidious. We present a clinical case in which diagnosis and therapeutic management were decisively guided by cardiac magnetic resonance.
