anyone remember the cardiomyopathy question.. the one where the showed you the pic of the crazily hypertrophied heart .. you could barely see the ventricles.. it was hypertrophied throughout equally. It asked you what the appearance was most consistent with:

a)alcoholic cardiomyopathy b)asd c)mitral stenosis d)primary pulmonary hypertension e)systemic hypertension

had to choose between those: I picked mitral stenosis, got it wrong. I was thinking hypertrophic cardiomyopathy w/outflow tract obstruction.

It was simply an enlarged left ventricle

Moreover, it was concentric hypertrophy. Therefore it was simply a case of afterload (systemic hypertension)

Plus that image is from the Utah Website images...

How would you tell the difference though? The terminology is confusing. Concentric hypertrophy can occur w/ essential hypertension and hypertrophic cardiomyopathy according to Goljan.

Does the term "hypertrophic cardiomyopathy" imply a genetic basis? Does it imply a completely different pathophys than with hypertrophy in response to HTN? If so, is the thickening of septum and mitral valve movement towards it --> unique to hypertrophic cardiomyopathy? And lastly, is there a different "look" to hypertrophic cardiomyopathy?

HCM is almost always genetic and occurs in much, much younger individuals than normal (like early 20s/teens). It's a sarcomere defect. You would see asymmetric hypertrophy of the septal wall compared to the other walls of the LV and as a result you get outflow obstruction. MCC of death is due to ventricular fibrillation since the fibers are disorganized and you have a higher rate of arrythmias.
