Appreciate your response. I have a right facing aorta with an abhorrent left subclavian artery and a Kommerelis Diverticulum. This is mentioned in 3 of the articles. I am in Canada and have had one open heart surgery where they had to go through the back because of the backwards aorta pressing too high against the sternum (and because the abhorrent left subclavian had embedded into my spinal column). Some work was done but the KD is still there and is at 5.7 cm. The hybrid technique has been mentioned but I didn't really understand it. My cardiologist has said he was looking into it. It is probably more challenging bring in Canada and I'm not sure how that will work for me (surgery in the US).
