Abstract

According to the 2011, ACCF/AHA guideline for the diagnosis and treatment of hypertrophic cardiomyopathy (HCM), the morphologic diagnosis of HCM is based on the presence of a hypertrophied as well as non-dilated left ventricle in the absence of another cardiac or systemic disease capable of producing the magnitude of that hypertrophy (usually ≥15 mm in adults or the equivalent relative to body surface area in children). Although the papillary muscles (PMs) are an anatomic part of the left ventricular (LV) chamber, the significance and diverse morphology of these structures in HCM has not been characterized in literature. Papillary muscle (PM) hypertrophy is a rare echocardiographic finding, with very few cases reported in the literature. Therefore, solitary PM hypertrophy can have clinically important for the screening of HCM as a newly identified subtype of or an early form of HCM. We are reporting the same case in which papillary muscle hypertrophy was a culprit for HOCM.
