The results of reconstruction of the aortic root performed on 9 patients by Svensson's method were examined. Nine subjects comprised 6 men and 3 women aged 23-69 years. In the preoperative diagnosis, annulo-aortic ectasia (AAE) was found in 7 cases, acute Type A aortic dissection in 1 case and AAE accompanied by chronic dissection after AVR in 1 case. Every patient underwent reconstruction by direct implantation of the right coronary artery button and interposition grafting for the left coronary artery, using a composite valve graft made of SJM valve and collagen coating artificial graft. Although one patient was lost due to multiple cerebral infarction, no marked changes were observed in other 8 patients. Angiography at short-term after operation showed no problems in the composite valve graft, and revealed good coronary arterial flow. Now, 2-62 months after operation (41 months on average), no late death occurred. On angiography of 2 cases performed after a long-term period, patency of the interposition graft was excellent. The early and late results of aortic root reconstruction by Svensson's method appeared favorable.
