Would asd and pfo cause right atrial and ventricular hypertrophy? if so why?

Over load: Right atrium and ventricle are dealing with 1.5 to 2 times of the blood volume with the shunt that is why it gets dilated and hypertrophied.

Enlargement: ASD causes enlargement of the right side of the heart. Not hypertrophy unless it (rarely) has led to pulmonary hypertension. Pfo is not a disease. Almost 20% of healthy people have it.
