4-D MRI flow analysis in the course of interrupted aortic arch reveals complex morphology and quantifies amount of collateral blood flow
Interrupted aortic arch is a rare congenital cardiac defect. There are extremely few cases in adults that are reported in the pertinent medical literature. However, single-stage repair of interrupted aortic arch combined with coronary artery disease has been rarely reported. We describe the management of interrupted aortic arch associated with coronary artery disease through single-stage surgical procedure without cardiopulmonary bypass in a 56-year-old woman. The vascular prosthesis was anastomosed between the aortic arch just distal to the origin of the left subclavian artery and the descending thoracic aorta. Then a venous bypass was subsequently formed between the left anterior descending coronary artery, the circumflex artery, and the descending aorta.
