[Interposition graft technique for the treatment of AAE (annuloaortic ectasia) with aortic regurgitation: surgical results].

Interposition graft technique had been used exclusively in 8 consecutive patients with AAE and AR. Two patients with severely dilated left ventricle (CTR 65, 80%, LVDd 93, 83 mm, LVDs 86, 68 mm), and 1 patient complicated with the postoperative mediastinitis died in the perioperative period, 10, 145 and 135 days after surgery, respectively. In the remaining 5 patients, excellent clinical improvement was observed with the reduction of CTR and echo-cardiographic findings without formation of hematoma, pseudoaneurysm, and leak from the suture lines on DSA and CT.
