1. Your aorta and pulmonary arteries have not been 'bent out of shape, or enlarged, by pulses by the two big pumps, the ventricles. IOW, those pumps are not beating too strongly for the condition of your aorta and pulmonary arteries (the latter takes venous blood, oxygen poor, from the right ventricle back to the lungs. The pulmonary veins, four of them, take newly oxygenated blood from the lungs back to the left atrium where it is pumped through the mitral valve and down into the left ventricle. The left ventricle pumps the enriched blood up the aorta, through the aortal valve, and on to the rest of the body. Remember, if this sounds confusing, veins all take blood back to the heart, even the pulmonary veins with the oxygen-rich blood, and arteries take blood away from the heart, including the pulmonary arteries that take spent blood back to the lungs for a resupply).

2. Your heart and pericardium, the bag around the heart, all appear healthy and normal, not scarred, holed, diseased.

3. Not entirely sure about this, but extra-coronary means not-of/in-the-heart, and this suggests that your carotid and femoral arteries are clear. Good for you if that is the case.
