This is a good question! You have to keep heart inside the cage. Because it is important structure. So you have thoracic cage. You can avoid aortic arch by keeping the heart in inverted position. But in that case blood flow would have gushed to the lower extremity. Important organs like brain would get less blood supply. Unimportant organs like lower extremity will get more blood supply. To avoid this problems the heart is placed in upright position. It has got the mechanical advantage. The brain and upper extremity gets direct blood supply. The arch will not create any problem to the blood flow. There is no sudden folding of the blood vessel. That would create problems to the smooth flow of the blood. Cells in the blood are very much delicate ones. They would have got ruptured. That would have created havoc. There will be clotting of the blood inside the blood vessels. Due to arch structure of aorta, important organs get initial high blood pressure. These are the obvious mechanical reasons. Someone should improve the answer.
It is an aortic arch with an aneurysm.
Is a right sided aortic arch normal?
It is an aortic arch with an aneurysm.
The aortic arch is closer to the base of the heart.
The aortic arch arches to the left as it emerges from the heart.

Why would you want to do that. You would have to cut open the heart and watch the blood move from the pulmonary artery through the heart and into the right radial artery.
The aortic arch is located in the thoracic cavity. It is a curved blood vessel that gives rise to branches that supply blood to the head, neck, and upper limbs.
