What is cardiac remodling?

change in the shape and function of a ventricle

6

Describe dilated cardiomyopathy.

enlarged ventricle that is more massive and has a more rounded shape; always involves the LV but usually is all 4 chambers

Describe hypertrophic cardiomyopathy.

a genetically inherited form; LV is hypertrophied but not dilated; usually disproportionate hypertrophy of the septum

8

What is restrictive cardiomyopathy?

infiltration or fibrosis of the ventricles, usually without dilatation

9

How does dilated cardiomyopathy present?

HF with a large silent heart with impaired systolic function

10
