(Created page with "'''Organ''': Heart '''Description''': A slice of the heart can be seen. Most notably the left ventricle is severely dilated. Note that the ventricular wall isn’t abnormally thick. '''Diagnosis''': Dilatative hypertrophy of the left ventricle '''Causes''': * Increased preload ** Aortic insufficiency ** Mitral insufficiency '''Theory''': This topic is best understood in tandem with preparation 17. When there is an increased preload, more blood volume will enter t...") |

# The Laplace law states that increased dilation of the ventricle causes increased strain on the ventricular wall. This increased strain causes a decrease in contractility. | # The Laplace law states that increased dilation of the ventricle causes increased strain on the ventricular wall.

# The decreased contractility eventually results in the ventricle not being able to compensate for failing heart, causing decompensation. | # The decreased contractility eventually results in the ventricle not being able to compensate for failing heart, causing decompensation. | ||
