Final answer:
In significant chronic aortic insufficiency, M-mode/two-dimensional evidence includes hyperkinesis of the interventricular septum, hyperkinesis of the posterior wall of the left ventricle, left ventricular dilatation, and paradoxical interventricular septal motion.
Step-by-step explanation:
In significant chronic aortic insufficiency, M-mode/two-dimensional evidence usually shows:
- Hyperkinesis of the interventricular septum
- Hyperkinesis of the posterior wall of the left ventricle
- Left ventricular dilatation
- Paradoxical interventricular septal motion
Therefore, the answer to the question is none of the options: A. Hyperkinesis of the interventricular septum, B. Hyperkinesis of the posterior wall of the left ventricle, C. Left ventricular dilatation, or D. Paradoxical interventricular septal motion is excluded in M-mode/two-dimensional evidence of significant chronic aortic insufficiency.
