The aorta first aims upward (ascending), then bends over (aortic arch), then proceeds downward through the chest (descending). Coarctation of the aorta is effectively when the aorta is formed in a way that it has a pinched place, frequently at the far (distal) end of the arch or in the beginning (proximal) part of the descending aorta, obstructing the normal flow of blood. The "dimple" he was referring to is likely just a minor indentation in the descending aorta that was not corrected by the surgery. His apparent lack of concern with it would indicate that he also sees it as harmless, or at least not actionable. They always note everything they see, to show that they have been thorough, and just in case it turns out to have meaning later, in the context of other findings.
As far as the double-sided cath: it's quite reasonable to do one to research PH. However, I still stick with my suspicion about the echo tech's judgement being off. Apparently, it was off for both the valvular regurgitation and the PH, from the cath results. I think the double-sided heart cath might have been avoided by a second echo - done by a different tech - which might have shown very different results. Also, the second tech should not see the results of previous echoes, as it tends to taint their numbers. They anticipate the diagnosis and the results.
I might even wonder if the results might have been crossed with someone else's. I had an emergency CAT scan for suspected lung cancer once because of an X-ray physician's right-hand-left-hand mixup of two X-rays.
At least you're sure of where you stand with the PH and aortic regurgitation - you don't have them. Even if you don't know what you do have, it's better than knowing you have a condition that will deteriorate to eventually be life-threatening.
Best wishes,
