A 70-year-old woman with a bicuspid aortic valve had undergone ascending aorta replacement for acute DeBakey type I dissection. Computed tomography and aortography 2 months after the operation revealed a thrombosed false lumen in the ascending aorta proximal to the prosthetic graft. However, recurrence of dissection was found at the aortic root proximal to the graft 4 years after the initial operation. Significant aortic stenosis was also noted. Despite intensive medical treatment, she had refractory and progressive heart failure. At the second surgery, an aorto-right atrial fistula, which probably was responsible for the severe heart failure was revealed. Closure of the aorto-right atrial fistula, and aortic root replacement were performed using Piehler’s method, with a composite graft. The etiology and management of this rare case are discussed.
