Isolated papillary muscle hypertrophy: A gap in our knowledge of hypertrophic cardiomyopathy?

Isolated papillary muscle hypertrophy: A gap in our knowledge of hypertrophic cardiomyopathy?

Increased thickness of left ventricular walls is the predominant characteristic and one of the diagnostic criteria of hypertrophic cardiomyopathy (HCM). This case illustrates an uncommon but important finding of isolated hypertrophy of the papillary muscles (PMs), observed in a young woman in whom an abnormal electrocardiogram was initially detected. During the investigation isolated PM hypertr...

Differentiation of solitary papillary muscle hypertrophy from apical hypertrophic cardiomyopathy.

Hypertrophy From Apical Hypertrophic Cardiomyopathy To the Editor: We read with interest the article by Reddy et al1 regarding a case with apical hypertrophic cardiomyopathy. The authors said that the 2D echocardiograph obtained from this patient indicated hypertrophy of the apex and that 201-Tl scintigraphic imaging demonstrated an increased count in the apical segment. However, because there ...

Basal antero-septal anomalous papillary muscle in hypertrophic obstructive cardiomyopathy

Hypertrophic cardiomyopathy without asymmetric hypertrophy.

A 49-year-old women with congestive heart failure and heart block died of cerebral embolism. Clinical and echocardiographic findings suggested a diagnosis of atypical dilated cardiomyopathy with predominantly right ventricular involvement. At necropsy, all the cardiac chambers were slightly dilated and the interventricular septum and the left ventricular wall were of normal thickness and symmet...

Isolated Papillary Muscle (PM) hypertrophy is characterized by an asymmetric hypertrophy of one PM without hypertrophy

Isolated Papillary Muscle (PM) hypertrophy has been supposed to be a phenotypic variant of hypertrophic cardiomyopathy. Whether this finding may explain an electrocardiographic pattern of left ventricular hypertrophy has to be demonstrated. A cardiac magnetic resonance imaging may add additional crucial information. Our case was a 26-year-old asymptomatic male cyclist who underwent routine spor...
