Hypertrophic cardiomyopathy (HCM ... The ECG shows a systolic anterior motion of the mitral valve (SAM), mitral regurgitation, left atrial dimension of 48 mm (normal, <40); LV end-diastolic ...

The obstructive form, which represents about two-thirds of the entire HCM population, occurs when the mitral valve moves abnormally, in a manner that causes obstruction of blood flow between the ...

HCM is typically characterized by asymmetric ... LV outflow tract obstruction and systolic anterior motion of the mitral valve. There is an increased incidence of diastolic dysfunction, atrial ...

Hypertrophic Cardiomyopathy (HCM): A condition characterized ... Mitral Regurgitation (MR): A heart valve disorder where the mitral valve does not close properly, allowing blood to flow backward ...

Mitral valve prolapse occurs when portion(s) of one or both of the mitral valve leaflets or the tissue filaments (”chordae”) that hold these leaflets in place become floppy and allow these leaflet ...

In HOCM, the increased velocity in the left ventricular outflow tract decreases pressure in this region causing the anterior leaflet of the mitral valve to be pulled in that direction. This is ...
