“…Coronary angiography (CAG) revealed a suspected single coronary artery (SCA) anatomy with diffuse atherosclerotic narrowing, without evidence of other coronary ostia in the aortic root. The diagnosis was confirmed on cardiac computed tomography (CCTA) as the SCA of the R-I type by Lipton classification. …”

“…The most extensive anastomoses between the cardiac and extracardiac vessels are around the ostia of the pulmonary veins. It was possible not only to demonstrate the passage of injection mass from the coronary arteries into the vessels of surrounding structures, but also to show vessels in the heart injected through the thoracic branches of the aorta. …”

“…Thoracoabdominal aortic aneurysms (TAAA) present special challenges for repair due to their extent, their distinctive pathology, and the fact that they typically cross the ostia of one or more visceral branch vessels. Historically, the established treatment for TAAA was open surgical repair, with the first procedure reported in 1955. …”
