Abstract
|
|
|
|
Abnormal insertion of the papillary muscles is rare and has been described only in patients with hypertrophic cardiomyopathy based on findings of echocardiography or autopsy. Herein, we reported a rare case of abnormal insertion of the papillary muscle in a 64-year-old man without cardiomyopathy, incidentally detected by cardiac computed tomography (CT). Multiplanar long-axis and three-dimensional volume-rendered reconstructed images revealed an abnormally inserted papillary muscle, which did not provoke left ventricular outflow tract obstruction. This is the first report of the anomaly in a healthy individual who was initially assessed by cardiac CT.
