Multimodality Imaging in Hypertrophic Cardiomyopathy Associated With Anomalous Hypertrophied Papillary Muscles: A Case Report

Multimodality imaging can help rule in/out the diagnosis of hypertrophic cardiomyopathy (HCM) in patients with significant left ventricular (LV) hypertrophy.. We describe a 73-year-old woman referred to us for consultation because of a giant negative T wave on her electrocardiography. Echocardiography revealed diffuse severe hypertrophy associated with hypertrophied anterolateral papillary muscles with a bifid head and with extensive wall insertion into the apicolateral segment. Three-dimensional echocardiography and cardiac magnetic resonance confirmed these data. Importantly, automated function imaging determined the global longitudinal strain at -10.2%.. According to our multimodality imaging approach, hypertrophic cardiomyopathy was the most probable diagnosis..
