In a prospective randomized study immediate results of aortic root reimplantation surgery were analyzed in comparison with David’s operation in patients with ascending aortic aneurysm and aortic regurgitation. There were no valve-related complications and mortality in the early postoperative period. Reimplantation technique reduces the time of operation using cardiopulmonary bypass and myocardial ischemia time. This type of operation is effective and safe and its functional results are comparable with conventional David’s surgery.
