Objectives: The pathophysiology of midventricular obstructive hypertrophic cardiomyopathy (MVO) is unknown. Patients with MVO and MVO-like cardiomyopathy were classified into three groups based on the cardioimaging morphological characteristics of the left ventricle to investigate their complications and treatment.
Methods: Four patients with MVO and one patient with disease-like MVO were admitted in our hospital from 1999 to 2005.
