The hypertrophy can involve the left and/or right ventricle, be symmetric or asymmetric, involving the septum, free wall, mid-ventricle, or apex. The phenomenon of solitary papillary muscle hypertrophy is rare with only 2 references in the literature. Furthermore, giant negative T and U waves are 2 common electrocardiographic phenomena in hypertrophic cardiomyopathy and have been attributed to hypertrophy of the posterior papillary muscle. Solitary hypertrophy of the anterior papillary muscle might be a new echo-electrocardiographic syndrome.156438 bytesapplication/pdfenSage Publications.
