Final answer:
A pressure overload of the right ventricle can cause echocardiographic findings such as D-shaped left ventricle, right ventricular dilatation, and right ventricular hypertrophy.
Step-by-step explanation:
A pressure overload of the right ventricle may produce all of the following echocardiographic findings except (D) Small, protected right ventricle.
When there is a pressure overload on the right ventricle, it will cause it to work harder and adapt by undergoing hypertrophy (thickening of the muscle) and dilatation (enlargement of the chamber). These changes can be observed using echocardiography. Additionally, the pressure overload may also cause the left ventricle to become D-shaped due to the increased pressure pushing against the septum.
